This is the last time the victim leaves a clue before dying. In a few later shows (The Adventures of "The Wary Witness," "The Two-Faced Woman," The Tyrant of Tin Pan Alley," "Caesar's Last Sleep,") detectives think they have found a dying clue, but it is either there by coincidence or, in one case., is a red herring planted by the killer.
During the late 1940's actor Howard Duff, who plays Eddie Morgan, starred on CBS and later NBC radio in "The Adventures of Sam Spade", one of the most popular detective dramas of the period.
William Schallert, although his role and stature would qualify him for billing in the opening credits, is listed as a "lco-star" in the end credits, between Tom Reese (Sgt. Velie) and Wheel of Fortune (1975) hostess Susan Stafford, (a cameo as a hat-check girl).
William Schallert has a major role in this show as a wine expert working for the victim (because of an injury, he was unable to meet with the victim before the murder - this is a vital plot element). However, Schallert's distinctive voice is not heard in the available clips; his dialog is dubbed over by a voice artist with a substantially higher -pitched voice and a vaguely European accent.
