When a Man Marries is an easy, fun mystery about a group of socialites who find themselves quarantined in a mansion after a dinner party. Jewelry goes missing, there are secret trysts and mistaken identities...it's wonderful! A young artist, recently divorced by his wife, finds that his aunt is soon to visit. The aunt, who contributes to the family income and who has never seen the wife, knows nothing of the domestic upheaval. How the young man meets the situation is humorously and most entertainingly told. Mary Roberts Rinehart (1876-1958) was an American writer, often called the American Agatha Christie, although her first mystery novel was published 14 years before Christie's. She is considered the source of the phrase "The butler did it", although she did not actually use the phrase. She is considered to have invented the "Had-I-But-Known" school of mystery writing.
