Story based on the Kelley Roos novel If the Shroud Fits (1941); in Roos's book series the main characters are named Jeff and Haila Troy. They are the same characters who appear in A Night to Remember (1942) with Brian Aherne and Loretta Young playing mystery writer Jeff and his wife Nancy Troy.
Working titles: "Restless Lady" and "The Case of the Dangerous Blondes."
The following year, stars Allyn Joslyn and Evelyn Keyes made a film considered an unofficial sequel: Strange Affair (1944). Their characters have different names, and they are a comic strip artist and his wife who investigate a murder.
Evelyn Keyes' character laments "four points!" for a tiny pot roast in the oven, reflecting WWII U.S. rationing, where a small roast (1-2 lbs) cost about 4 ration points, as beef required 7-12 points per pound.
