Sister Margaret, A Tommy Keane Novel

Veteran NYPD Detective Tommy Keane has arrived at his new command in Manhattan, after receiving an unwanted and punitive transfer from the Bronx, where he had spent the last nineteen years as a police officer, and detective, chasing criminals responsible for every sort of crime imaginable.
His new assignment, in the comparatively quiet 21st Precinct, should be an easy and safe way for Tommy to finish out the next thirteen months until his retirement date arrives, one would think. But the grizzly and shocking murder of a well-known and celebrated nun will prove, that while crime in supposedly nicer neighborhoods may not be as prevalent; crime, especially homicides, in any neighborhood are always disturbing, cruel, and surprising cases to investigate.
Even for a detective as well seasoned as Tommy Keane.
