The time: 10:00 pm, New Year's Eve, 1947. The place: The ballroom of the Hotel Astor. The victim: Mr. Marcus Halliday. And the suspects (all the usual ones): the son (and his gold-digging girlfriend), the untrusted nephew, the long-time secretary (and her brand new fiance), and the new business partner (of course, stealing from the company behind the victim's back). The soon-to-be victim has just announced that he plans to disinherit all of the above before the night is out - only to be found minutes later, slumped over in a nearby phone booth. Can Ellery figure out the clues as they play out? Of course, he can. But can you?

A wealthy heiress dies. She jumped off the balcony of her elegant home (or did she?). Was it suicide... or was it murder? The twist: she was reading one of Ellery's own murder mysteries at the time and she died exactly the same way as the victim in the book.

On a fishing trip to the town of Wrightsville, Ellery and Inspector Queen are dragged into the case of the murder of a wealthy man who was whacked over the head with an ornamental dog figurine meant as a wedding gift for his daughter and worth nearly half a million dollars.

Ole Frank Flannigan is on the scene too trying to steal some of the glory.

Ole Frank Flannigan is on the scene too making the usual nuisance of himself and trying to beat Ellery to the solution. They'll have to take things one day at a time in this case.

Ellery and his agent, Howard Biggers, travel to the estate of the wealthy and eccentric Spencer Lockridge. It seems as though Biggers wants to turn one of Ellery's books into a play and is trying to get Lockridge to provide the financial backing.

Could it have been someone from New York or maybe even Dallas?

Heeeeeeeeeeere's Ed. Ed McMahon, that is, who plays a once brilliant but now seemingly senile inventor who is murdered in his electric train workshop.

The Queens investigate when a wealthy industrialist and war profiteer is stabbed to death with a Chinese ceremonial dagger and then dragged out of his house and hung from a tree with a crown of thorns placed on his head.

Not in this episode, he doesn't.
