Bob Langmuir is an obsessive dealer with a remarkable eye for treasure who makes the discovery of a lifetime when he chances upon a trove of never-before-seen prints by the legendary Diane Arbus. From the moment he purchases a trunk containing the archive of Hubert’s Dime Museum and Flea Circus—a midcentury Times Square freak show frequented by Arbus—and discovers some intriguing photographs, he knows he’s on to something. Furthermore, he begins to suspect that what he’s found may add a pivotal chapter to what is now known about Arbus and the “old weird America,” in Greil Marcus’s phrase, that Hubert’s inhabited.

Langmuir’s ensuing adventure, filled with bizarre coincidences, turns into a roller-coaster ride that takes him from memorabilia shows to the curator’s office at the Metropolitan Museum of Art. Will the photos be authenticated? How will the Arbus estate react? most important, can Bob, who has seen more than a few promising deals head south, finally make his one big score?
