Plunged into the alien world of the super-rich, where the basements are bigger than the house and dangerous, arcane items are bought and sold on the open market, a sensible young copper would keep his head down and his nose clean. But this is Peter Grant we're talking about.

Peter Grant is learning magic fast. And it's just as well - he's already had run-ins with the deadly supernatural children of the Thames and a terrifying killer in Soho. Progression in the Police Force is less easy. Especially when you work in a department of two. A department that doesn't even officially exist. A department that if you did describe it to most people would get you laughed at. And then there's his love life. The last person he fell for ended up seriously dead. It wasn't his fault, but still.
