Tony initiates a sweep to find a pair of missing cops; devises an ingenious way of keeping an habitually drunk driver off the road; and deftly handles an "extraterrestrial," all the while being scrutinized by a committee searching for a new police commissioner for New York City.
Tony is doubly stymied when identical twins both initially confess to the same murder, then, in a surprise about-face, accuse each other of the crime. Also, Arnie finds romance with a kindred soul, a phone-sex operator named Gloria.
During the holiday season, Tony investigates the murder of an elderly woman allegedly killed in her home during a Christmas burglary; matches wits with a mugger, and defends a homeless woman who's been sleeping in the manger of a Holy Family creche.
A mugging triggers a woman's repressed mernosy of her brother's murder, which she witnessed as a child. The suspect, free for the past 35 years, is tracked to the unlikeliest of hiding places by Tony and a visiting friend, L.A. homicide detective Paulie Pentangeli.
