- Awesome Music: The jazzy opening theme is so much fun, not to mention perfectly capturing the main character and the spirit of the series.
- Complete Monster:
- Season 2: Sidney Fletcher seems to be a charming man, but he actually runs a white-slavery operation wherein he scouts out "sinful" young women held at a convent and buys them, only to smuggle them out of Australia and into sex slavery. When one young woman escapes, Fletcher decides she's not worth the trouble and has her murdered before having her dumped in the river. When Phryne Fisher investigates, Fletcher catches her and demonstrates willingness to kill her and her friends in order to keep his sickening trade going.
- "Murder Under the Mistletoe": Nicholas Mortimer is the most prolific murderer in the series. When he discovered that a mine which he partially owned had gold in it, Mortimer sent in miners who were trapped in a cave-in. When a ten-year-old boy escaped and told Mortimer, Mortimer personally murdered him and rigged a second cave in to kill the miners so as not to have to tell anyone else about the gold. Years later, Mortimer learns that Phryne's aunt Prudence wants to sell her stake in the mine and begins murdering everyone at the hotel they're at to deal with Prudence and any witnesses. Just for a sadistic flair, he bases his murders around the 12 days of Christmas song, knowing the song tormented Prudence when she thought she heard the trapped miners singing it. Mortimer even murders his own wife as not to share the wealth with her, admitting that he did it all for money and fun.
- Fight Scene Failure: The show is very good when it comes to suspense and making you suspect the wrong killers. However, when it comes to fight scenes, not so much. An example can be seen in 'Away With The Fairies' where Phryne and Camellia fight against Lin Chung's cousins—-the fighting looks messy and painfully not real.
- Ensemble Dark Horse: Dr. Mac is beloved by fans, even though she only appears in about half the episodes.
- Narrowed It Down to the Guy I Recognize: Miranda Otto appears in the pilot as the grieving wife of the murder victim. Unsurprisingly, she killed him. But then again, you probably guessed that from reading the trope description.
- One True Pairing: Judging by the fandom, Phryne and Jack are very rarely, if ever, shipped with anyone but each other.
- They Wasted a Perfectly Good Character:
- Phrynes cousins, Guy and Arthur, are introduced at the end of season one. They are not seen or mentioned in season two, and by season three, its revealed that Arthur died, and Guy is overseas with his new wife.
- Janes appearances dwindle to the point where shes not seen or mentioned in season three.
- Phrynes mother is frequently mentioned in season 3, but is never seen on screen.
- They Wasted a Perfectly Good Plot: Overlaps with Fridge Horror, but when its revealed in Death At Victoria Dock that Lilas brother and stepmother were having an affair, the questions of how long the affair was going on and the paternity of the stepmothers unborn child arent touched on.
- Unintentionally Unsympathetic: "Blood on the Wheel." It's very hard to be sympathetic towards the obviously sexist Lachlan Pepper and his attempt to pass a law that would be ridiculous by modern standards, but the heroic characters don't help their case by rigging the race so that females can have better representation in the VCC.
