Chaosium Inc to adapt RIVERS OF LONDON as a roleplaying game

Chaosium Inc., best-known as the creators of the classic Call of Cthulhu roleplaying game, has licensed Ben Aaronovitch's Rivers of London urban fantasy series for a new pen-and-paper RPG.

The game will use Chaosium's own rules set, customised to reflect the magic used in the books.

The game is at an early stage of development, so I'd be surprised if we saw it this side of 2021. Simon Pegg and Nick Frost are also developing a TV series based on the books.

The Rivers of London series so far spans Rivers of London (2011), Moon Over Soho (2011), Whispers Under Ground (2012), Broken Homes (2013), Foxglove Summer (2014), The Hanging Tree (2016) and Lies Sleeping (2018), as well as related novellas and graphic novels.
