Right as Rain (Large print ed)

Derek Strange is an ex-cop who's making a good living with his own business, a detective agency called Strange Investigations.

A new case hits him close to home: a police officer has been killed by another policeman in a confusing late-night clash, and the dead officer's mother asks Strange into the darkest chasms of the DC underworld, where police officers and criminals operate by their own secret laws.

Strange is joined in his quest by Terry Quinn, the officer who was exonerated in the police inquiry.

Together Strange and Quinn confront the ravages of an unquenchable drug trade, the realities of race in the capital police force, and some of the most implacable, dead-eyed killers ever to haunt the pages of a novel.
