From a Wall Street Journal book review by Tom Nolan headlined “‘Genealogy of a Murder’ Review: A Tragic Triangle”:

In her 1999 book “Show Me a Hero,” the journalist Lisa Belkin chronicled a volatile public-housing battle that embroiled Yonkers, N.Y., in the late 1980s and early 1990s. Her latest investigation, “Genealogy of a Murder,” centers on a fatal shooting that took place in Connecticut on July 7, 1960.

She outlines her story in an introduction: “A young army doctor is stationed at a research lab at a maximum-security prison and becomes friendly with a prisoner, one who himself is a subject of the doctor’s research. The prisoner asks for the doctor’s help, the doctor gives it, things go terribly wrong, [and] a police officer is murdered.”
