M. G. Eberhart

Mignon Good Eberhart was an American author of mystery novels. She began publishing in the 1920s and kept writing into the 1980s, one of the longest careers among major American mystery writers. Her books often placed an ordinary woman, frequently a nurse, in the middle of a murder, and The Patient in Room 18 is an early example. Readers returned to her for plain storytelling and a steady supply of suspense across several decades.
