Full Dark House by Christopher Fowler
My rating: 4 of 5 stars
Summary: Edgy, suspenseful, and darkly comic, here is the first novel in a riveting new mystery series starring two cranky but brilliant old detectives whose lifelong friendship was forged solving crimes for the London Police Department's Peculiar Crimes Unit. In Full Dark House, Christopher Fowler tells the story of both their first and last case--and how along the way the unlikely pair of crime fighters changed the face of detection.
A present-day bombing rips through London and claims the life of eighty-year-old detective Arthur Bryant. For his partner John May, it means the end of a partnership that lasted over half-a-century and an eerie echo back to the Blitz of World War II when they first met. Desperately searching for clues to the killer's identity, May finds his old friend's notes of their very first case and becomes convinced that the past has returned...with a killing vengeance.
