The Killer's Mark

Every mark tells a story. This one ends in blood.
The next darkly funny thrill-ride of a book in the Sunday Times bestselling Washington Poe series. 'Dark, funny and twisty' - Lisa Howells, Crime Monthly 'One of the greatest duos in crime fiction' - Mark Sanderson, The Times 'Craven's trademark mix of dark humour and drama is so addictive it should come with a health warning' - Matt Nixson, Daily Express A MONSTER. A MOTHER. A MURDER?
When Vice Admiral Boyer, RN (retd) died without leaving a will, his estranged daughter inherited his - not inconsiderable - estate. Called home to sort through his belongings, she found an AegisBox - a tamper proof safe within a safe designed to self-destruct if anyone without the code attempts to open it. Unable to walk away without the truth, she uncovered something so horrifying it launched the biggest investigation in the National Crime Agency's history. Five years later, Washington Poe is unwittingly, and unwillingly, sucked into its gravity... Finally able to escape the authority they railed against, Washington Poe and Tilly Bradshaw are enjoying their new jobs as private detectives or - as the sign on their door says - 'Gumshoes for Hire'. When a teenage girl walks into their office, looking for the mother she long believed to be dead, they agree to take the case. As Poe and Tilly investigate the girl's claims, they find themselves drawn into a murky world of trafficking, pornography and prostitution. Will they be able to help the girl find her mother, or will the dark forces at work, who will stop at nothing to protect themselves, get there first...
