Notes:
- "Copyright 1942 by Avon Book Company."
- No statement of printing; likely 1st printing.
- Title page states "Wood Engravings by Howard Simon," referring to b/w illustrations throughout the pages of the book. Cover artist not explicitly stated, and there is no visible signature.
- Catalog number "1" on front cover, base of spine, and title page.
- According to information in the 9th printing, there were five Avon printings from 1942-1945, presumably shared between this publication and Avon's pb-size publication #26. The latest advertised release of Avon's "pocket-size" books on the inside back cover is #18. In addition, the outside back cover advertises #2 in the "Avon Murder Mystery Monthly" series as "ready next month." So this is likely the 1st overall printing by Avon, and the 1st printing under this catalog number.
