Ralph Bellamy makes the third of four appearances as "master detective" Ellery Queen in Columbia's Ellery Queen and the Perfect Crime. The principal villain is crooked stockbroker John Mathews, whose Wall Street manipulations render Ray Jarden penniless. Mathews' chicanery seems particularly coldblooded, inasmuch as his daughter Marian is engaged to Jarden's son Walter. When the latter disappears, Mathews asks Ellery Queen to locate the young man.
