The novel “Destroying Angel” by Richard Paul Russo was published for the first time in 1992. It’s the first in the Frank Carlucci series.

Louis Tanner left have the police for some time and one of the cases in which he was involved that remained unsolved concerns a serial killer who threw the bodies of his victims in the San Francisco bay with angel wings tattooed on their skin. The murders stopped for unknown reasons for a few years but suddenly restart.

Tanner can’t pretend nothing’s happening and reconnects with Frank Carlucci, a former colleague still in the police. At the time of the first investigation, Tanner was contacted by a criminal who claimed to have information useful to find the serial killer and he was listed as the person to meet to communicate such information. After the the murders restarted, that old trace may be the only one useful to solve the case.
