What the Night Knows

I liked this book written by Dean Koontz. In the late summer of a long ago year, a killer arrived in a small city. His name was Alton Turner Blackwood, and in the space of a few months he 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, recreating in detail Blackwood’s crimes. Homicide detective John Calvino is certain that his own family – his wife and three children – will be targets in the fourth crime, just as his parents and sisters were victims on that distant night when he was fourteen and killed the slayer.
