The Cold Smell of Sacred Stone — George C. Chesbro

He's an ex-circus performer turned hard-boiled New York private eye - with a Ph.D. in criminology and a black belt to boot. He's also a dwarf - which creates some curious problems even as it gives him special insight into the slings and arrows that pierce the human heart.

Mongo has created a monster...or a Messiah. His brother, Garth, lies in a coma. Only Mongo knows of the genetic secret that has put Garth beyond ordinary medical help. Mongo initiates his own high-risk therapy, and the gamble pays off. But Garth awakens spouting parables and performing miracles. The world is ready to hail a 'new Messiah' even as the KGB and a ninja assassin stand ready to turn a saint into an angel of death and a cult of love into a snake pit of evil.
