What The Night Knows

Description for WHAT THE NIGHT KNOWS by Dean Koontz:

In the late summer of a long-ago year, Alton Turner Blackwood brutally murdered four families. His savage spree ended only when he himself was killed by the last survivor of the last family, a fourteen-year-old boy.

Half a continent away and two decades later, someone is murdering families again, re-creating in detail Blackwood's crimes. Homicide detective John Calvino is certain that his own family -- his wife and three children -- will be targets, just as his parents and sisters were victims on that distant night when he was fourteen and killed their slayer.

As a detective, John is a man of reason who deals in cold facts. But an extraordinary experience convinces him that sometimes death is not a one-way journey, that sometimes the dead return.
