Synopsis by Hal Erickson
Jessica (Angela Lansbury) shows up on Wall Street, there to make her very first personal investment in the stock market. As inevitably as night follows day, Jessica's stockbroker promptly turns up murdered. The police figure that the dead man's secretary is the culprit...but as usual, Jessica doesn't take stock (ouch!) in the conventional wisdom, and sets out to find the real murderer on her own.
