Intro: A cat may have nine lives but Scarroth lives in twelve different times. That has advantages for him and sets up at least a dozen problems for The Doctor as he and Romana attempt to cope with the "City of Death."

Outro: Drifting along with the tumbling tumbleweeds. That's a poetic notion of a popular western song. A cowboy or anyone else would be well advised to give a wide berth to the tumbleweeds on the planet Chloris as we shall learn next week when The Doctor, Romana and K-9 meet "The Creature from the Pit."
