The Wind In My Heart [Wynne, Douglas]

Miles Landry is trying to put violence behind him when he takes up work as a private detective focused on humdrum adultery cases. But when a Tibetan monk hires him to find a missing person, things get weird fast.

Charged with tracking down the reincarnation of a man possessed by a demonic guardian from the Tibetan Book of the Dead, Miles is plunged into a world of fortune-tellers, gangsters, and tantric rituals. The year is 1991 and a series of grisly murders has rocked New York City in the run up to a visit from the Dalai Lama.

The police attribute the killings to Chinatown gang warfare. Miles-skeptical of the supernatural-is inclined to agree. But what if the monster he's hunting is more than a myth?
