Rivers of London: Black Mould Series by Ben Aaronovitch, Andrew Cartmel

It creeps! It crawls! It ooooozes! Something dark and slimy is dripping through the walls of suburban London. Not usually a police matter but there's something very weird about this mould. Police Constable Peter Grant and his unwilling partner, Sahra Guleed, soon find themselves knee deep in killer muck! Meanwhile, their boss, Thomas Nightingale, is preparing to do battle against a haunted ice cream van. Good times.

There's a mould problem in South London. Not the usual stuff that smells funny and can be hell on the lungs. This mould is possessed by some dark power full of bad intentions and it's another case for London's one and only trainee wizard cop, PC Peter Grant!

The book store hit returns for more dark and dangerous urban fantasy! The third series in the best-selling original comic series, based on the award-wining novels by Ben Aaronovitch!
