Richard Allistar Disappears in Vacant Lot

Boston Blackie is a fictional character created by author Jack Boyle (1881–1928). Blackie was originally depicted as a jewel thief and safecracker in Boyle's stories, an antihero who maintained his own code of honor and was fiercely loyal to friends. Blackie's image was softened for radio, film and television depictions, where he became a private detective and was described as an "enemy to those who make him an enemy, friend to those who have no friend."
