Rinehart is known for murder mysteries, in the style of Agatha Christie. She is credited with coining the phrase “the butler did it!” She also created the “had-I-but-known” style of mysteries. The best fact about Rinehart is that she created a costumed “super-criminal” she named “The Bat” which was adapted for the 1930 movie, “The Bat Whispers”, inspiring Bob Kane’s creation of “Batman” first published in Detective Comics in May, 1939. This story isn’t a murder mystery, but it’s fun and sweet. Enjoy!
