Was Amelia Earhart lost on a secret mission that the U.S. government covered up? Is Mrs. John Manahan of Charlottesville, Virginia, really Anastasia? Will Jimmy Hoffa's disappearance ever be solved? Is Martin Bormann still alive? Several of Hayman's 13 turn up also in Daniel Cohen's two entries, Missing (p. 330, J-84) and Mysterious Disappearances (1976); and though Hayman dishes a bit more dirt on Judge Crater's political cronies and Michael Rockefeller's collecting ploys, his Bermuda Triangle rehash is even more sensational, his general approach more slapdash. But why bother with comparisons? For missing persons, this lot has become highly visible.
