CRIME DOCTOR'S MAN HUNT (1946). Director: William Castle.
A man is stabbed to death and a woman at a shooting gallery at the carnival seems to know more about it than she's telling. The victim walks into a certain house and then seemingly vanishes. Can Dr. Ordway, the Crime Doctor (Warner Baxter) get to the bottom of it? This is an acceptable mystery (with a somewhat obvious solution) that is greatly abetted by the participation of William "Fred Mertz" Frawley and the ever-delightful and unique -- and uncredited -- Olin Howlin (pictured) as Marcus LeBlaine. Howlin, of course, had interesting roles in Them and The Blob (first victim), among others. Ellen Drew also has an interesting role.
Verdict: Passable minor mystery. **1/2.
