An awards dinner sponsored by the Crime Writers of America is being held at the residence of writer Edgar Manning who is the recipient of the Blunt Instrument Award. Ellery is not present at the dinner due to the fact that he's home sick with a head cold. Nasty, egotistical Manning calls up Ellery on the telephone in order to gloat about his win and is murdered while speaking with our hero on the phone. It might take a quantum leap for our hero to solve this one.
