Somehow the ending of THE PEARL OF DEATH was picked up and plunked down into MURDER, MY SWEET: The unarmed Detective in the dark, faced up against Miles Mander and a hulking brute, turns the tables through his understanding of the relationships between the characters. I wonder if the writers at RKO ever acknowledged this swipe from Universal? At any rate, both films make good use of lighting and creepy sets to exploit the situation, and both directors (Dmytrick & Neill) know how to use the limited acting skills of Mike Mazurki and Rondo Hatton to best advantage. I liked Rathbone's pithy comment to the Police when they arrive to catch the baddies, "You won't need your revolver. Nor handcuffs. Worthy of a hard-boiled Private Eye in any film noir!
