A detective with a unique gift, a tragic suicide and big city corruption - 'The Fallen' is the stunning new thriller from the author of 'The Blue Hour': 'a great writer... he's amazing' Lee Child

What if you could tell someone was a killer just by looking at them?

Detective Robbie Brownlaw can. A six-storey plunge from a burning hotel leaves him with the usual broken bones - and something different. Synesthesia. The ability to see words and emotions as colours makes Robbie a human lie detector.

It's a condition that might have helped Garrett Asplundth. Hired to look into rumours surrounding a certain madam's Little Black Book, Garrett found a lot more than the usual round of losers and sad husbands. But the dirt came at a high price.

Now he's dead and it's only when Robbie gets hold of the book that he finds out just why Garrett was so curious - and why others will kill to get it back...
