Robert J. Randisi

He's been called astonishingly prolific. He's been called "the last of the great pulp writers."

Robert J. Randisi has fought to ensure that P.I. fiction gets some respect, not just through his many splendid contributions to the genre in the form of his fictional eyes creations of Miles Jacoby, Henry Po, Nick Delvecchio or a host of others, as entertaining as they may be, but through his tireless promotion of the genre through his numerous non-fiction articles, his co-founding, with Ed Gorman, of Mystery Scene magazine and most of all through his founding of The Private Eye Writers of America in 1981.
