According to the New York Times of July 28, 1946, Senator Robert Taft (R–OH) was a devoted mystery fan, with his favorite authors listed as Anthony Berkeley Cox, Dorothy Cameron Disney, and Dorothy L. Sayers.

It seems to have run in the family. His father, President and Supreme Court Chief Justice William Howard Taft, also enjoyed detective stories.
