Episode 9, "The Deadly Gift" served as the Christmas entry, with Sandra Dorne playing pretty barmaid Rosie Holland, better known as 'The Duchess,' who receives a belated gift from a famous thief dead for 10 years, a music box that comes forth with "The 12 Days of Christmas" (recalling the 1946 Holmes adventure "Dressed to Kill"). George Coulouris plays her solicitor, Harwood, who hoped the box would contain a valuable emerald, and is murdered by a mysterious assailant searching for it. A lyric from the song offers a vital clue to Colonel March, who discovers the secret hiding place of the emerald before trapping Harwood's killer. Tommy Duggan pops up as Lawton, Rosie's boss in the pub, and John Gabriel plays a jeweller, but Coulouris is totally wasted in a nothing part. Sandra Dorne soon appeared with Christopher Lee in both "Police Dog" and "Alias John Preston," did two episodes of THE AVENGERS, and featured prominently in 1960's "Invisible Creature" and 1963's "Devil Doll" (performing a daring topless scene).
