Firefighters find a body, but it’s clear that the blaze was only an attempt to cover up for murder. Who would want to kill the quiet Henry Nelson, a man who kept to minding his own business? What will the cops and Casey turn up from questioning neighbors, or his employer?
Though not much has been turned up on Henry, Casey notices plenty about the body language of his boss. Being as astute as he is, why doesn’t Casey pick up on the hints that Ann drops about marriage and engagement rings?
In the Blue Note, Casey seems in a blue funk and not talkative at all when Ethylbert talks to him. Has Ann’s hints begun to sink in just a little? Ann enters, and suddenly Casey snaps back to his usual self, with inspiration to track down a killer.
Back on the crime scene, Casey scours the place for hiding places, or clues that were missed before. Suddenly a man jumps both Casey and Ann, and escapes with the clues that were just found. Or almost all the clues. Able to narrow down the suspects greatly, Casey sets out to trap his man.
Confronting their man, Casey and Ann get their revenge for the thumps on the head. Then in the Blue Note Casey shares with Ethylbert how he figured it all out. Will Ann get a little romance out of Casey?
