Otto "Big Red" Amlingmeyer, a German-American cowboy in the 1890's, finds himself stuck as The Watson to his brother Gustav "Old Red", a taciturn (yet illiterate) detective studying the methods of Sherlock Holmes. The brothers gradually make both friends and enemies throughout their cases, which provide an interesting mix of action-adventure, and detective fiction. The novels follow the brothers' journey from wannabe sleuths to near Great Detective status.
1. Holmes On the Range: The brothers are hired by a ranch, owned by absent English aristocrats, and observe lots of mysterious behavior from the regular employees. Then the ranch manager dies in a mysterious stampede, the owners of the ranch arrive for an inspection, and the brothers find themselves investigating their first big case.
2. On the Wrong Track, working as railroad detectives, the Amlingmeyer's encounter train robbers, a famed Pinkerton Detective, a woman who is not what she seems, a Chinese archaeologist trying to bring home some priceless artifacts, and more.
4. A Crack in the Lens, the brothers journey to look into the years old death of Old Red's fiancee, encountering a resentful lawman, sinister pimps, and strong indications of a local Serial Killer.
5. World's Greatest Sleuth: The brothers find themselves competing with lots of others detectives, including their old friend Diana, to win a $10,000 prize, and some much needed publicity, only t get involved in a deeper mystery when the contest organizer turns up dead.
6. The Double-A Western Detective Agency, now working as part of a larger agency, the brothers journey to take a job that lands them in the middle of a race-fueled range war.
7. Dear Mr. Holmes, a short story collection, set at various points in the brothers lives.
Holmes On the Range contains examples of:
- A True Story in My Universe: Exaggerated. Every detective story published in magazines, from Sherlock Holmes, to Nick Carter is presented as having been sold as factual memoirs (although many such as Carter and the fictional "Billy Steele, Boy Detective" are fabrications by the authors), with the Alingmeyer brothers publishing their own.
- Accidental Aiming Skills: In 'World's Greatest Sleuth Big Red shoots the gun out of a bad guys hand, but later whispers to Old Red that he was aiming for his head.
- Actually, That's My Assistant: Done deliberately in World's Greatest Sleuth. King Brady has an actor act as his proxy during the competition while he remains out of the public eye, and because his publisher doesn't want people knowing that he isn't exactly sex symbol material.
- Ascended Fanboy: Old Red is quite pleased to go form a mere reader of Holmes stories, to solving similar cases himself.
- The Atoner: In A Crack in the Lens Bob and Lottie are helping them partially out of friendship, and partially because They took the money that Old Red and Adeline were going to use to start a new life together after she died and used it to buy themselves a fresh start.
- Bait-and-Switch Tyrant: Milford Bales in A Crack and the Lens is a bit too obsessed with keeping unsavory elements out of his town and is utterly convinced that Old Red is a murderer, but is ultimately willing to hear them out, and does a capable job investigating on his own.
- Brains and Brawn: Big Red is the tougher brother, Old Red is the smarter one, although Big Red isn't stupid, and Old Red can handle himself in a fight.
- Broken Bird: There's an air of stoic sadness to Clara from the first book, after her father drove away the man she loved, humiliated her mother with affairs, gambled away her inheritance and treats her like dirt, with her Motive Rant after being exposed diving deeply into The Dog Bites Back.
- Brutal Honesty: In On the Wrong Track, Colonel Crowe tells the brothers that he is only hiring them because he's of his confidence that neither is a spy for the train robbers, as they are completely unqualified for the job, and the last people he would normally hire, while the train robbers would have someone with an acceptable resume.
- The Cameo: The fifth book features an appearance by Holmes himself, using the alias he had in The Adventure of the Empty House.
- The Cavalry: in the sixth book it turns out that a few other mysterious figures lurking around are new hires to the agency who Colonel Crowe sent to help them out after finding out more about their job.
- Chekhov's Gunman: Jim Weller, an African-American cowboy from the first book is initially just a man who isn't hired along with the brothers to show what a Jerkass Ully McPherson is, but later turns up looking for Hungry Bob Tracy, hoping to collect the bounty, and working with the brothers. His being excluded from the hiring by a ranch which does hire black men also serves as an early clue to Tall John being a spy- Ully was only going t count down seven men from the lien and hire them, and Tall John had let himself get pushed to eighth place.
- Clueless Deputy:
- Local deputy Jim Martin in the first book (his boss is never actually seen) is a bit unimaginative and described as cowering during the final fight.
- Tommy in A Crack in the Lens is earnest, and brave, but a bit gullible and impressionable.
- Flip Compton, the deputy in The Double-A Western Detective Agency is a reasonable man, but a bit slow, and easily overwhelmed. This actually works in the brothers favor, as he is happy to let them take point in the case after his boss is murdered, and listens to their insights.
- Comically Cross-Eyed: Averted with Swivel-Eye Smith in the first book, who is the least comical of their fellow cowboys.
- Dead Person Impersonation: In the first book, Perkins was murdered well before the events of the series by a man who needed to impersonate him, Clara's husband, Nathaniel.
- Dirty Cop; Quite a few ,but Inspector Mahoney in The Black Dove stands out.
- Disposable Sex Worker: The death of Old Red's "Soiled Dove" fiancee in the backstory of A Crack In the Lens didn't get much focus. and the deaths of another prostitute every year on the anniversary of her death avoided notice completley.
- Extremely Short Timespan: The average duration of a story is three days, although the first book follows a longer period of time and the epilogue of A Crack in the Lens follows them for a couple weeks after the main events of the book.
- Farmer's Daughter: Fiona and Eileen from the short story The Water Indian showing the brothers quite a bit of attention while their stopped at the house.
- First-Person Smartass: Big Red's narration is filled with puns, and dry quips at those he dislikes.Big Red: Some fellows are born with huevos so large they could bluff their way out of hell itself. Tall John was not such a man. A fox with a mouthful of chicken feathers could hardly have looked more guilty.
- French Jerk: Downplayed with M. Valmont in World's Greatest Sleuth, who clashes a bit with the brothers over their instance that the mysterious death was murder, but isn't overly condescending or thick-headed.
- Hard Boiled Detective: King Brady is considered one, although he strikes the brothers as being too much of a dandy, until until they meet the real one. Nick Carter is also mentioned, disdainfully, a few times.
- Heroic Self-Deprecation: Big Red isn't afraid to admit his own failures, particularly when it comes to not figuring out the case.The clan Kennedy had taken my brother and me for fools. And alas, they'd been half right.
- Hooker with a Heart of Gold: All of the ones seen or mentioned in, A Crack In the Lens, except for Big Bess, although it's made clear that Unproblematic Prostitution is not a phrase they would use to describe their lives.
- I'm a Humanitarian: Escaped killer "Hungry Bob" Tracy, whose presence lurks in the first book.
- It's Not You, It's My Enemies: In a non-romantic version, in A Crack in the Lens, Old Red pretends to suspect Bob and Lottie] of the murder to angrily drive them away at a key point in the investigation and get them out of danger.
- I Want Grandkids: Mr. Kennedy from the short story The Water Indian is eventually revealed to have a bad case of this. The fact that his family is the only one left in the area and he refuses to move elsewhere in order to find sons-in-law that way doesn't help.
- Jack the Ripoff: The long ago murder of a prostitute in A Crack in the Lens has some resemblance to this. and then it turns out there were a bunch of similar murders, and indeed the killer has a bunch of books on Jack the ripper in his house.
- Living Legend: King Brady and Burl Lockhart.
- The Mole: Tall John is spying on the rest of the new hands for Spider and his brother in the first book. In On The Wrong Track Kip the newsboy is working with the train robbers.
- Motor Mouth: Big Red is a talkative guy, although this is often justified by a need to stall or distract people as part of the investigation.
- Narrative Profanity Filter: The series isn't shy about swear words but uses the word "fudge" instead of fuck ( it's even a running gag with Gus Bock) while noting that "fudge" isn't the actual word being used.
- Never Learned to Read: Old Red is illiterate, with the family having spent all of their money on Otto's schooling.
- Never the Obvious Suspect: The culprit is rarely anyone that Big Red gave too much scrutiny to.
- Mistaken Confession: In A Crack in the Lens it turns out that the reason that Milford Bales hates Old Red is because he mistook Old Red's drunken It's All My Fault speech after Adeline was murdered as him confessing that he'd killed her.
- Overprotective Dad: Colonel Crowe is this to his adoptive daughter Diana, and shows some irritation in the brothers interest in her.
- Perpetual Frowner: Old Red is a reserved, often sour person.
- Perpetual Smiler: Sergeant Ryan is described as having a permeant glow to his expression.
- Pinkerton Detective: The brothers spend the first several books trying to join the agent and getting turned away, before setting out to make their own agency.
- Poirot Speak: One of the other detectives in, World's Greatest Sleuth, which fits, given that he's an Expy of Hercule Poirot.
- Police Are Useless: Often averted, although the brothers are the ones to do the real mystery-solving, the actual authorities are generally competent at their jobs (although there are exceptions).
- Jim Martin is a bit of a blunderer and somewhat cowardly in the first book, but is introduced out searching for an escaped killer, and during Old Red's summation, gradually shows signs of believing him. He spends the final shootout that follows this cowering in a corner, but does get off a couple shots, one of which might have hit Ully [McPherson.
- The brothers themselves are the police (railroad police anyway) in On the Wrong Track, and while a bit gruff, Colonel Crowe is a fairly shrewd fellow, who has another agent planted on the train who also does a good job.
- Mahoney from The Black Dove is an active menace to the characters and has no interest in catching a killer, but is corrupt rather than incompetent.
- Milford Bales in A Crack in the Lens spends a lot of the novel hostile and pursuing a vendetta against Old Red, and has obviously overlooked quite a few crimes in his town over the last five years, but he does come around and prove helpful in the end, and has forced the local Den of Iniquity to relocate to outside of city limits. His deputy also works to prevent the brothers from falling victim to a lynch mob. The county sheriff on the other hand, is an utter jerk who is either complicit or willfully blind in everything that's been going on.
- Sergeant Ryan in World's Greatest Sleuth is described as "Shockingly Reasonable" in the appendix, and while he does voice the belief that the death was an accidental one, he voices some decent logic for doing so, is shown to still be thorough investigating things anyway, and ultimately doen't obstruct the brothers at a key point in the case.
- Marshal Hinkle in The Double-A Western Detective Agency is a fair-minded, inviting man who works hard to keep the peace and doesn't kowtow to corrupt local interests, while his deputy Flip Hinkle is an earnest, well-meaning guy who steps aside and lets the brothers and Diana do their thing when the choice is in his shoulders.
- Played completely straight with Marshal Nickles, from one of the short stories in Dear Mr. Holmes. Nickles is a bullying, bigoted man who is quick to seize the obvious solution and reluctant to admit that he's wrong
- Revealing Cover Up: In the first short story, Old Red observes that a suspicious drifter taken in by the cattle drive kept demanding everyone stay away from his saddle bags, which naturally made everyone more curious about them. Said saddle bags turn out to contain Proof that the man is a wanted fugitive. This is inverted when Old Red deduces that he was deliberately baiting them into looking into his saddlebags as part of a Batman Gambit to trick the cattle drive into taking him to the nearest town to turn him in for the reward, when a party of bushwhackers planning to kill them and steal the herd were waiting outside of said town.
- Play-Along Prisoner: In one short story, when an outlaw is arrested by a man who Old Red deduces is Impersonating an Officer, after they've exposed and captured that man, Old Red tells them to keep an eye on the prisoner who'd just been "arrested" and they catch him suddenly untied, and about to go for a gun, with Old Red pointing out that since they were staging the whole arrest it obviously made sense to leave the guy not tied very tight in case anything went wrong and he needed to fight or flee.
- "Scooby-Doo" Hoax: The short story The Water Indianhas the brothers stay at a farm and encounter a supposed local spirit risen by Native American magic and haunting the area. Naturally, it is no such thing, and, as Old Red quickly suspects, is being used to accomplish an earthly purpose. Namely, their host, Mr. Kennedy, tying to keep them from leaving until he can have his daughters seduce one of them, as well as to scare off any Mormons who try to settle in the area.Old Red: Well, sir, [[Sherlock Holmes usually I make it a point not to have any prejudices and to just let the facts lead me where they will]]. But it turns out I've got me one prejudice I can't shake. I don't believe in spooks and monsters.
- Seen It All: Sergeant Ryan notes that he's seen some very bizarre deaths in his sixteen years as a policeman, including a woman who was accidentally strangled to death by her own hair.
- Shaming the Mob: A Crack in the Lens features an example that's only clear in retrospect. The heroes have been Wrongfully Accused of murder and tossed in jail. It quickly becomes clear that a mob is forming to attack and lynch them once it gets dark. From a distance, they observe Brother Landrigan who they've had several clashes with earlier in the novel adressing the mob. At the time, they speculate he's helping stir them up. Later, they're told that the verse he was reading was John 8:7, "Let he who is without sin cast the first stone." It fails to break up the mob, but later Landrigan (and several other supporting characters) do it more successfully (and with a little physical force added in) when the mob is literally on top of the brothers.
- Sherlock Homage: Old Red. World's Greatest Sleuth also features Boothby Greene, an amateur British detective trying to cash in on the wake left by Holmes, who is still one of the more gracious and perceptive detectives in the competition. Even though he's the murderer.
- Siblings in Crime: Ully and Spider [McPherson brothers in the first book, who are pretty blatantly up to something criminal from the moment they appear. The same is trued of hired gunmen Knute and Konrad Karlsvik in the sixth book.
- Sibling Yin-Yang: Suspicous, quick-fisted Ed Sweeny, and his genial, accommodating brother Johnny in The Double-A Western Detective Agency. And then of course there's the Amlingmeyer brothers themselves.
- Sole Survivor: Otto was the only Amlingmeyer (save for Gustav, who was absent) to survive the flood which destroyed the family farm.
- Stealth Expert: Subverted. In one short story, Old Red is suspicious specifically because Big Red was able to sneak up behind a man (observing that Big Red "ain't exactly comanche material when it comes to stealth") and deduces that the guy let them do this.
- Suicidal Overconfidence: Although he's since grown out of it, Old Red and Bob's friend "Suicide" Cheney got his nickname for stunts like trying to put a saddle on a bull and ride it.
- Summation Gathering: Old Red naturally does these at the end of each case (although often with the clear indication that it's building up to some kind of fight), most impressively when does so in front a crowd of hundreds of people (along with the Crowe's, and the various suspects) in World's Greatest Sleuth. Subverted in A Crack in the Lens where first he and Big Red are alone with the sheriff and try to convince him of what they have figured out so far (which isn't everything), and later, once they have a complete picture, the brothers are Alone with the Psycho and desperately trying to stall while being held at gunpoint. World's Greatest Sleuth also has M. Valmont do this, but he's largely bluffing, not having any definite conclusion of his own yet, and hoping to sir things up.
- Took a Level in Badass: Several characters, but notably Mr. Brackwell in the first book, a young Sheltered Aristocrat, who goes on to help the brothers with both the case, and the final shootout, and is described as looking more like a man when he leaves.
- Train Job: In On The Wrong Track There's a multi-tiered one, first one train robbery that simply robs a few passengers, then a greater one when the leaders of the gang remain hidden onboard the train, holding the express clerk hostage, while planning to steal the heavier, and more valuable stuff in the baggage car later on.
- Was It All a Lie??: Both Old Red and Milford Bales loved Gertie in A Crack in the Lens, and received signs that she loved them back, and at the end are left wondering if she was merely manipulating one or both of them in order to make enough money to quit the life.
- Unholy Matrimony: The murderers from the Crack in the Lens.
- The Watson: Big Red rarely picks up on the clues himself but is always there to provide a witness to Old Red noticing them, and to his deductions being revealed.
