Ellery must track down the killer of noted fashion designer, Monica Gay, who pulled the plug out of her clock and her TV set as a cryptic dying message. The three main suspects are Monica's financier lover, his jealous wife, and hot-tempered son who'd been having an affair with her himself. Each is charged and then cleared of murder but are they really innocent? Ellery must sort things through.

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?

Beloved Vera Bethune stars as Miss Aggie in a radio soap opera, but is about to be written out. One day she drinks water from a jug and is poisoned in a murder attempt. She is taken to the hospital and survives, but the killer returns.

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. This one's a toughie because it appears as though no one could have entered or left the workshop during the time in which the murder must have taken place.

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. Just like one Judas Iscariot. As usual, plenty of suspects abound and when it's discovered that the victim was dying of acute lymphoma the plot only thickens.

Frank Flannigan probably wishes he'd taken a vacation as he's made to look foolish on the infant medium known as television. The plot concerns the murder of a nasty advertising executive for the Quick Silver Tobacco company which was thinking about sponsoring a radio show starring Flannigan.
