In this legal thriller with “bedrock authenticity” by a New York Times–bestselling author, a Manhattan prosecutor risks his life to catch a serial killer (Kirkus Reviews).

A veteran assistant district attorney, Butch Karp knows that sometimes a prosecutor has to make a deal. The Manhattan courts are backed up worse than Midtown at rush hour, and that means plea bargains. Burglary gets knocked down to trespass, attempted homicide down to simple assault, but Karp has one ironclad rule: In his office, nobody gets away with murder. That rule is about to get put to the test.

All over Manhattan, the city’s drug kingpins are getting shot in the head and dumped in the streets. Is it a turf war, or has someone in the NYPD turned vigilante? When a cop asks Karp to help kill the investigation, Karp is forced to make an impossible choice between his principles and the city he loves.

Based on the personal experience of legendary prosecutor Robert K. Tanenbaum, Reversible Error takes readers on a tour of the grittiest corners of 1970’s New York. “You can smell the Big Apple starting to rot, ” writes Kirkus Reviews “as Tanenbaum bores into its mealy core for another uncommonly intelligent legal/cop entertainment. ”
