Forensic psychologist Alex Cross's storied career in private practice, with the FBI and as a Washington, D.C., cop has brought him into contact with all kinds of seriously disturbed killers, but his 12th outing from bestseller Patterson (after 2005's Mary, Mary) may be the ultimate in lunatic deadliness. Beginning with a flashback to the murder of Cross's wife, Maria, Patterson quickly introduces Michael Sullivan (aka the Butcher of Sligo).
