Peter Grant is part of a very special London police unit. Full-time cop and part-time wizard, he works on rather unusual crimes – those that involve magic and the general weirdness that permeates London’s dark underbelly. In the first volume, Body Work, Police Constable Peter Grant and his boss, Thomas Nightingale, London's only wizarding cops, tackle a case that begins with a perfectly innocent car on a homicidal killing spree – without a driver. But then, before you know it, there’s a Bosnian refugee, the Most Haunted Car in England, a bunch of teenagers loaded on Ketamine and a seemingly-harmless wooden bench with the darkest of pasts… In the second volume, Night Witch, Peter and Nightingale are press-ganged into helping a Russian oligarch hunt his missing daughter, where they are caught up in a battle between Russian gunmen, a monstrous forest creature - and their nemesis: The Faceless Man. But as Grant and Nightingale close in on the missing girl, they discover that nothing about this case is what it seems! In the third volume, Black Mould, something dark and slimy is dripping through the walls of suburban London. Not the usual stuff that smells funny and can be hell on the lungs, this mould is possessed by dark power and worse intentions. Looks like it's another case for London's one and only trainee wizard cop, Peter Grant, joined here by his reluctant partner, Sahra Guleed!
