Jack Be Dead: Revelation - Jack Be Dead, #1

London-Today- "Jacks" are being killed across the city by a female serial killer with an almost supernatural ability to stay hidden. When Jack Tate, an emotionally bleak Detective Sergeant, is called in to investigate the brutal killings, he teams with Mae, an intellectual wannabe-detective, and Albert, Mae's packrat psychic father, to unravel the killer's taunting clues, until the devastating truths behind the killings force Jack into a dark revelation that is centuries old and bathed in blood.
Karma is a bitch, and then you die-if you're lucky.
