Ellery Queen - Season 1 - Eps 13: The Adventure of the Sunday Punch
A boxer is killed while training for a championship bout and the finger points towards his sparring partner, Joe Adams. Joe's girlfriend, Corrinne Ogden, seeks out Ellery for help in clearing her boyfriend's name. Ellery accepts the challenge of proving Joe's innocence but it seems that the dead boxer had nearly as many enemies as Bugs Moran. Making things even more complicated is the fact that good old Frank Flannigan is also on the scene trying to beat Ellery to the solution.
