Mantis: A dark and disturbing thriller

Throughout history, London has been the hunting ground for many killers: Jack the Ripper, Amelia Dyer, and Dennis Nilsen, to name a few.
As the years passed, advances in technology and forensics gave the police an edge. But as the police advantages progressed, criminals grew smarter, more cunning, more inventive.
What happens when the criminals start using the same knowledge for their own means?

In the heart of London, on the same streets stalked by some infamous killers, men are going missing and their bodies found days later in sinister circumstances.
The Metropolitan Police, headed by Detective Sergeant Catherine Jones, have nothing to go on except for grainy CCTV images that hint at multiple killers.
Can Catherine and her team figure out what’s going on before England’s capital becomes the setting for another tale of murderous debauchery?
