Trivia: Rivers of London
- One of Us: Aaronovitch has name dropped a couple of trope names outright in the series and has presented Peter as one of the best examples of geek-culture as the protagonist.
- Schedule Slip:
- The ever changing release date of the third and fourth novels, the former which slipped from June to October and the latter which slipped from a June release to November.
- The Hanging Tree's release date has slipped from June 2015, to November 2015, and then all the way to June 2016.
- Unintentional Period Piece: A strangely recent example, but on his blog, Aaronovitch frequently laments that the Met reinvents itself so often the books are instantly dated. Usually this just means he has to change exactly what the Folly's official designation is, but in Broken Homes he came up with the phrase "Working together for a stranger London" as a play on the Met slogan "Working together for a safer London", and they immediately stopped using it.
- What Could Have Been: Word of God states that the book series was originally meant to be a TV series described as Prime Suspect meets Ars Magica. Paul McGann would have played Nightingale and Peter would have been a woman named Simone. There would have also been an entire team of wizards working for the Met.
