The Five Find-Outers and Dog are five friends living in Peterswood Village who solve mysteries together with a dog, Buster. The Find-Outers are Laurence "Larry" Daykin, Frederick Algernon "Fatty" Trotteville, Philip "Pip" Hilton, Margaret "Daisy" Daykin and Elizabeth "Bets" Hilton. Buster the dog belongs to Fatty.
Apart from tackling criminals, the children have to face the wrath of the bumbling, interfering village policeman, P.C Theophilus Goon, who bears a grudge against Fatty for solving crimes before him. Recurring characters include Inspector Jenks, friend of the children, and Ern Goon, PC Goon's nephew who sometimes comes to stay with his uncle for the school holidays.

Tropes present in this work are:
- The Ace: Fatty excels in both his studies and sports (including poetry), is able to solve crimes better than the police, and is very rich too.
- Adults Are Useless: Wherever there is a problem the Find-Outers must resolve it.
- Beneath Suspicion: One of the suspects in The Mystery of the Pantomime Cat has such an airtight alibi the Find-Outers initially don't think it's worth checking. Guess who turns out to be the robber?
- Big Brother Mentor: Fatty towards Bets, more than her real brother.
- Cut-and-Paste Note: In one of the books, Goon starts receiving these from an anonymous source, trying to get him to look into a specific house. Goon is particularly annoyed by the fact that his name is always written in lower-case. This becomes a plot point that allows one of the kids to figure out which newspaper is being used for the words. The reason for the lower-case "goon" is because the full word is "Rangoon".
- Elective Broken Language: Downplayed in The Mystery of the Vanished Prince: Bets and her friends pose as Princess Bongawee and her retinue as a part of a prank. They speak broken English and their own made-up language.
- Embarrassing First Name: while it's never stated outright, surely Mr Goon has some issues with being named 'Theophilus'?
- Embarrassing Initials: Frederick Algernon Trotteville. And yes, he is fat.
- Embarrassing Nickname: Downplayed. Fatty doesn't really like being called Fatty (for obvious reasons), but he dislikes being called "Frederick" even more, so he puts up with it.
- Fat Bastard: Mr Goon. Totally averted with Fatty.
- Food Porn: The children's tea-time food is described often. A popular place for them to eat is a tea-shop, where they order buns and cocoa. There is also a dairy mentioned in The Mystery of the Vanished Prince, where they have ice-creams.
- I Never Said It Was Poison: A non-lethal example in Burnt Cottage, when the owner of the aforementioned cottage mentions seeing a flying display that took place a week ago on the day the cottage burnt down at a time when he was meant to be miles away on business, prompting Fatty to start the chain of deductive reasoning that leads to the children working out that the man burnt down the cottage himself as part of an insurance scam.
- Master Actor: Fatty; not only is he a Master of Disguise, but he can create a new character to match each disguise and act and react in that persona. He's never seen in-series as part of a formal stage performance, but he's downright brilliant at improv - look at how he finishes all of Ern's poems.
- Master of Disguise: Fatty.
- Minor Crime Reveals Major Plot: in both Hidden House and Pantomime Cat, a prank played by the children on a substitute policeman leads said policeman to the spot where a crime is being committed. It's especially awkward for the children in the second, because their most outlandish clues directly implicate one of the (innocent, naturally) suspects.
- Police Are Useless:
- Mr Goon. Several times he befriends the criminal, and refuses to rescue Fatty from their clutches. The children end up solving the crime before him. He is also very fat and unable to run fast.
- Averted with Inspector Jenks, who is also promoted several times during the series.
- Refuge in Audacity:
- Fatty's disguises. The scenes during Missing Necklace where he disguises himself as a waxwork figure are the peak of this trope in-series.
- The thief in The Mystery of the Invisible Thief, who goes into houses he's just robbed to search for the thief.
- Running Gag: There are several minor ones (including Fatty using his ventriloquism skills to prank Mr Goon), but the most enduring (and the funniest) is Ern's 'pomes', his constant Writer's Block, and Fatty always being to improvise a funny continuation to them. Also Fatty coming home to Petersville later than the others, who try to find him in disguise at the station; sometimes they find him (usually Bets), sometimes they don't.
- Sixth Ranger: in several books, Goon's nephew Ern shows up; he becomes almost as big a fan of Fatty as Bets. His attempts at poetry is the series' longest Running Gag. Whenever he visits, Ern spends as much time as possible far away from his uncle, because Goon's treatment of him varies between shouting, more shouting, and threatening to 'box his ears' or similar.
- Spotlight-Stealing Squad: The early books set up the Find-Outers around the Larry, Daisy and Pip trio, with Larry as the leader and Fatty and Bets as unwanted hanger-ons. By the third book Fatty takes over as leader and the rest of the series is pretty much "The Fatty Show" with Bets as his sidekick, while the others hang in the background. By the end of the series, readers know just to wait for Bets to drop a innocent observation that triggers Fatty cracking the case.
- Uncle Pennybags: Whenever the Find-Outers go out to eat, Fatty is the one who pays for it all, since he has much more money than the other kids. (It's also how he accumulates all his disguises; it's made clear it's not a very cheap hobby.) This is occasionally lampshaded in the narrative; whenever Larry or Pip are unusually flush for some reason, they insist on paying the next time.
- You Meddling Kids: Some of the villains say this. Goon occasionally complains about the children interfering in his job, despite the fact that he never could resolve the cases on his own.
