IMDb's contributors are correct. Actor George Sanders actually "wrote" two crime novels: "Crime on My Hands" (1944) was published under his name and is actually written in the first person. He even mentions some of his films. "Stranger at Home" (sic) followed in 1946. In actual fact, of course, the novels merely served to give Sanders added publicity. He wrote neither. The first was ghost written by Craig Rice, and the second by none other than Leigh Brackett. I've read neither but if the DVD of "The Unholy Four" is anything to go by, "Stranger at Home" presented an intriguing premise but little reader involvement. Certainly it's hard to get over-enthused by the film. The script is weighed down with talk, the direction is stolidly routine, and Paulette Goddard will disappoint her fans. She's neither clothed nor photographed to advantage. Admittedly, a couple of good performances saved the day. I always enjoy Russell Napier. I can usually take or leave Paul Carpenter, but in this case he delivers the best acting in the film. All the same, a movie in which Paul Carpenter shines is not exactly my idea of an engrossing film noir.
