The first victim is hung in crucifixion position-a gash in his side and a wreath on his head. Homicide detectives Dylan Black and Vivienne Sheffield are baffled by strange words written in Scrabble tiles, the dead man's discarded glass eye, and wolf hair left at the scene. The victim's neighbor, a college student and mythology buff named Trevor McDaniel, is convinced the victim is not meant to represent Jesus, as the detectives first concluded, but rather an ancient Viking god who was killed by a monstrous, mythical wolf. Four months later, the second murder is even more bloody and bizarre. The killer has beheaded, speared, and partially mummified a woman. This time he has painted Egyptian hieroglyphs on the bedroom wall and left behind a man's severed hand and seven scorpions. Eager for publicity, the killer writes self-aggrandizing letters to reporter Aggie Rhodes and signs them Fenrir the Wolf-naming himself after the mythical god killer. Soon Aggie realizes the madman is embedding messages about his crimes in the letters, and she vows to beat the monster at his own game. With few clues to go on, Sheffield and Black desperately search for answers with the aid of Trevor, Aggie, Chief Medical Examiner Nikolina Petkov, and friend and fellow officer Amadeo Perez. The investigation takes them from the zoo to the university to the morgue and even to a strip club. As the hunt progresses, Detective Black finds himself entangled in a secret relationship with Trevor-a relationship that just might alter the Wolf's next move. Can Black and Sheffield solve the Myth Murders before the Wolf kills again? Or has he already chosen one of them?
