What Doesn't Kill You — Ed James

The body of a young City lawyer is discovered on an East London building site, assaulted and brutally murdered. Initial enquiries lead DI Simon Fenchurch to a driver employed by Travis, a controversial new app-based cab company. Within days another woman -- a Travis driver -- is found murdered.

As the body count goes up, DI Fenchurch and his colleagues on the East London Major Investigation Team delve into the crimes and unveil a murky conspiracy that some will do anything to keep hidden.

When familiar faces begin to emerge from the shadows, Fenchurch realizes this case is more personal than he'd thought. Could he finally be on the brink of solving the mystery that has dogged him for over a decade: who abducted his daughter, Chloe -- and where is she now?
