Elizabeth Daly was born on October 15, 1878 in New York. Her father, Joseph Francis Daly, was a justice on the Supreme Court of New York County. Like most children, Daly was a fan of games and puzzles, a characteristic that she maintained throughout her life. This interest spurred a subsequent passion for crime fiction, and she was an avid reader of the genre. She graduated from Bryn Mawr College and went on to receive her Master of Arts degree from Columbia University a year later. It wasn’t until 1940, when she was sixty-two years old, that Daly published her first novel. In the following ten years, she wrote an additional fifteen mysteries and received an Edgar Award for her entire body of work. Among her fans was Agatha Christie, who was noted to have declared Daly her favorite American author. Daly died in 1967.
