Like with many of the fourth doctors adventures (at least the early ones that I’ve heard) there is something relatively slight and insubstantial about this story. I enjoyed the rogue employee from the insurance company who makes every effort to help the doctor - whether or not it helps his career. It's a shame he disappears when the master turns up. There is a nice bit of character development at the end for Leela but it’s disconnected from the story.

Another okay script and enjoyable performance from this 4th Doctor Adventure.
