Amos Decker returned from a stakeout one evening and entered a nightmare --- his wife, young daughter and brother-in-law had been murdered. His family destroyed, their killer's identity as mysterious as the motive behind the crime, and unable to forget a single detail from that horrible night, Decker finds his world collapsing around him. But over a year later, a man turns himself in to the police and confesses to the murders. Decker must endure the memories he would much rather forget --- and may have to make the ultimate sacrifice.
