Cool French cover art for Mignon G. Eberhart’s 1937 mystery novel Danger in the Dark, also known as Hand in Glove, and released in France by Presses de la Cité in 1947 as Une clameur dan la nuit, which translates as “a scream in the night.” A man means to stop the distant cousin he loves from getting married, but when her fiancée turns up dead the two relatives decide to make the scene look like a robbery to avoid the police suspecting them of murder. But who did the killing? Eberhart had a long and distinguished literary career, typically mixing her mysteries with strong elements of romance and ending up with Christie-meets-Harlequin. This is a prime example, but a well reviewed book.
All her problems turned out to be relative.
