Captain Marvel Jr #44 "CMJ Finds the Key to the Mystery"!(November 1946)
My copy of this issue is missing pages 2-5 of this story). This is a
story where Freddy Freeman and CapJr. play detective in solving a murder
mystery. Freddy's escape from the furnace is one of the more plausible
escapes we've seen in these stories. Lord Greystack is close to Lord
Greystoke (Tarzan). It appears that Bud Thompson was involved in this story's art.
