Precious Blood (Dr. Edward Jenner #1) by Jonathan Hayes

THEY FOUND HER IN THE EAST VILLAGE, NAILED TO THE WALL OF A RAILROAD FLAT

Dr Edward Jenner is a New York forensic pathologist: he has attended countless murder scenes and performed thousands of autopsies, but the killing of 21-year-old Andie Delore is different. The naked body is marked with an indecipherable ancient script and is arranged in the shape of a ritual sacrifice.

The murderer poses as a cop. The sole eye witness is Andie's flatmate, Ana de Jong. She can't trust the police anymore. Instead she turns to Jenner for help.

But then a second victim is found in rural Pennsylvania. Her head has been placed in a puddle of milk.

And then the third. Another decapitation: her naked torso is decorated with exotic bird feathers...

The corpses have the same mysterious script. The killer is leading Jenner and Ana into his own private nightmares. A place from which there will be no escape.
