We all really enjoyed tonight’s episode, in which Catweazle throws some military training exercises into complete chaos while searching for the sign of Capricorn. The main guest star is Tony Selby, who was in between series one and two of Ace of Wands, where he played Tarot’s original sidekick, Sam. Here, Selby plays a sergeant trying very hard to get this supposed “spy” to give up his name, rank, and number. Then Catweazle finds a live grenade and thinks it’s the Philosopher’s Stone. Just start counting the minutes until something explodes.
