The Devil's Mark

When a blood-stained effigy of body parts is found in a central London park, D.I. Daniel Graves must set about trying to discover what it could mean and find the person responsible. Symbols at the crime scene suggest the occult. Who would leave a murder victim in such a way, and why?

As Graves and partner D.I. Charlie Palmer begin to investigate the ritual and the act of human sacrifice, they enlist the help of Charlotte Gooding, a talented professor specializing in the subject. They hope to narrow down a motive—could the killer believe in the supernatural? Witchcraft, even? Then the next crime scene is found. More blood, more symbols, and out in the open. It seems the killer wants the world to pay attention, but why? How are they choosing their victims?

The pressure is on for Graves to put an end to the murders before more remains show up in brutal tableaus. One thing is for sure: this killer is out for blood, and they're not afraid to make it a very public display. There's just one problem. Grave's past still isn't behind him. Someone is eager to make sure he doesn't forget, that he cannot move on, and they're not playing games anymore.

There may be an occult killer out there, but now there's another out for blood—Daniel Graves's blood.
