Peter Grant hopes to be a detective one day but it seems his boss has other much less interesting plans for him. After a confusing murder Peter is stationed near the crime scene and he somehow manages to gain some very important information from a key eyewitness who just happens to be dead - Peter discovers he can speak to ghosts. This is where Detective Chief Inspector Thomas Nightingale comes in - he investigates crimes involving magic and other supernatural occurrences, and now he has an assistant, Peter. As the murders multiply, each one stranger than the other, we follow Peter on a journey while he rediscovers London - a place where Gods exist and the dead don't always stay dead.

This book is particularly enjoyable if you live or are familiar with London and has a touch of Neil Gaiman's Neverwhere - the feeling of there being much more going on beneath the surface. The everyday 'normality' mixed with hidden magic and power. Written with wit and humour, this book had me chuckling at the one liners and familiar slang on one page, and cringing at the detail used to describe the particularly gory and bizarre murders on another. I like a bit of London based nerdy urban fantasy sometimes so I'll likely pick up the next in the series - I think there are 9 in total so far?! the most recent released this year.
