Number 49. Edgar Wallace still holds the record for most stories and/or books adapted into films: 160. He also wrote the first screenplay for King Kong, much of which was used in the movie.
Some nice covers, but really prime maps in this batch. I wonder if the board game "Clue" (originally called "Murder" in 1944) was inspired by the Dell maps?
Number 143. Amazingly, Rim of the Pit is still in print, with the original map on the back!
Number 302. No info on Hannah Lees, other than one of her stories was made into a film called "Shadow on the Wall" starring Ann Sothern and featuring Nancy (Mommy) Davis and Barbara Billingsley. Sounds like a must-see.
Number 302 also had the very cool mapback endpapers.
Number 132. Leane Zugsmith seems like she was an interesting person. She was married to co-author Carl Randau.
Number 208. Cornell Woolrich also wrote under the pen-name William Irish. As Irish, he was the author of Marihuana. Sorry, I don't have a copy of that one.
Number 262. I believe Alfred Hitchcock and James Stewart were involved in the film business somehow.
Number 164. Alice Tilton was the pen name of Phoebe Atwood Taylor (1909 –1976). "The Adventures of Leonidas Witherall" was a shortlived radio series that ran for about a year on the Mutual network, 1944-1945. Taylor was born in Boston and many of her books take place around the city and Cape Cod.
