Set in a hospital, the play dealt with the issue of illegal abortion, 1930s medical and surgical practices, and the struggle of a promising physician who must choose to dedicate his life to medicine or devote himself to his fiancée.
Kingsley's two successes were followed by his 1936 anti-war play Ten Million Ghosts and his 1939 work The World We Make, which were both flops and had short runs.
Despite reaching the rank of lieutenant in the United States Army during World War II, soon after, in 1951, Kingsley's name was placed on the Hollywood Blacklist by HUAC, which ended his film career.
Meeting him in 1957, Michael Korda described Kingsley as "a short, powerfully built man with broad shoulders, a big head, and rough-hewn features that made him look like a bust by Sir Jacob Epstein".
[4] Kingsley hired Korda as an assistant to do research for a screenplay he was writing for CBS on the Hungarian Revolution which was never produced.
