"Death of a Great Dane" was one of the sloppier entries from the second season, perhaps one of the reasons it was remade as a color episode with Diana Rigg, "The 50,000 Breakfast." 50,000 pounds worth of diamonds are found in the stomach of an auto crash victim, an entertainer employed by the Litoff organization, which has been liquidating its assets for the past six weeks. Steed gets most of the footage in this one, supported by the wonderful John Laurie, making his series debut (he went on to do "Brief for Murder," "A Funny Thing Happened on the Way to the Station," and "Pandora"), Frederick Jaeger, remembered for playing Benson in "The Cybernauts" and "Return of the Cybernauts," Leslie French ("You Have Just Been Murdered"), and Anthony Baird ("Brief for Murder"). There were two dogs credited on screen, with Junia (the actual pet of Patrick Macnee) later appearing in "Concerto" (Steed even wonders how many weeks its been since the animal has had a decent tree!)
