Bag Men (Paperback, 1st Harvest ed)

It is New Year's Day, 1965, and the body of Father George Sedgewick is discovered on a snow-covered runway of Logan Airport. Gone missing are four thousand communion hosts consecrated by Pope Paul VI, meant to be given out to the faithful at the first English-language mass in America later that year.
Ray Dunn, a rising young assistant district attorney and the son of a corrupt cop, is assigned to the case. In another part of the city, legendary narcotics detective Manny Manning begins a desperate search for the shadowy source of deadly new heroin hitting the streets. This time Manny is determined to reach the top, but his adversary is cunning, brutal--and branching out into a strange drug called "acid."
These quests for a killer and a dealer will intersect, unleashing the ghosts of the past and unlocking the secrets of Boston's most powerful institutions. Authentic, knowing, and bracingly cynical, "Bag Men" is a powerful thriller that will keep readers on the edge of their seats.
