Map Back Monday: Helen McCloy's Do Not Disturb

It's been awhile since I've posted a Dell Mapback cover and Map for MapBack Monday. Love these old books.. great stories and great graphics. The perfect match. Today's Mapback is Helen McCloy's Do Not Disturb (1943). The book also has a cast of characters with descriptions. The Hotel Majestic is another hotel I won't be checking into any time soon.

I really like the Helen McCloy books.

Who's Calling? 

Helen McCloy (June 6, 1904 – December 1, 1994), is the pseudonym of Helen Clarkson. She was an American mystery writer, whose series character Dr. Basil Willing debuted in Dance of Death (1938). Willing believes, that "every criminal leaves psychic fingerprints, and he can't wear gloves to hide them." He appeared in 13 of McCloy's novels and in several of her short stories. McCloy often used the theme of doppelganger, but in the end of the story she showed a psychological or realistic explanation for the seemingly supernatural events.
