On a busy London street, a young woman is attacked in broad daylight and left bleeding to death on the pavement. Among the eyewitnesses are DI Simon Fenchurch and his wife. Fenchurch pursues the attacker through a warren of backstreets and eventually arrests a young hoodie with a cache of stolen phones-an 'Apple picker' on the make. The case should be closed but something feels off...Was this really just about a smartphone? Why did the victim look nervous before she was targeted? And why don't the prints on the murder weapon match the young man in custody? Before Fenchurch can probe further, his superiors remove him from the case, convinced he has let the real culprit run free. But Fenchurch is determined to get to the truth and, before long, uncovers a conspiracy that reaches high above the street gangs of London.
