When Larry Parks uses a Christmas show at the penitentiary to cover his escape, show arranger Boston Blackie (Chester Morris) needs to prove his own innocence -- and to explain how neither he nor Parks had anything do with a murder.
It's a typically fast-paced episode in the Columbia series, with the usual cast of character actors: Adele Mara as Parks' sister, George E. Stone as Blackie's assistant, Richard Lane as the police inspector, and Lloyd Corrigan, Paul Fix, and Cy Kendall rounding out the cast.
Blackie was created by Jack Boyle after he had spent time for kiting checks. A fix-up novel from the short stories was a success in 1918, and there were eleven silent films from 1918 through 1927, with performers like Lionel Barrymore, Bert Lytell and Walter Long playing the safecracker. Columbia revived the series in 1941, starring Chester Morris. In them, Blackie is a reformed crook who keeps having to help out pals and prove his own innocence. He also starred in a summer replacement radio show in 1944. There was a TV show from ZIV in the 1950s, and a graphic novel in 2002.
