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

Not in this episode, he doesn't.

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.

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?
