Norman Gannett

Classical composer, conductor, and murder victim from the exceedingly short, one-page story "Death Plays a Symphony" by Scott Feldman, in Pep Comics #32 (October 1942).

He's written a symphony, his 4th in D minor. Gannett's violinist, Robin Tana, has accused him of stealing it from him.

Hero The Hangman solves the case.
