First time in U.S. paperback, the third in Bill James's "standout," "witty," "well above the ordinary" series (starred reviews, Publishers Weekly, Booklist). When Detective Chief Superintendent Colin Harpur places young policeman Ray Street undercover in a vicious drug gang, the entire department knows the risks. If Street is found out, he will take his place in "the halo parade." Then the killing of a fellow officer will have to be avenged, by whatever means . . .
