Sigh! The more I re-watch of season 1, the more I get upset at the thought of Sinclair being replaced by Sheridan. I know I'm probably alone in this, judging by other people's comments, but there it is.

I loved everything about this episode, and unlike David McCallum, Christopher Neame doesn't disappoint as a guest star. Yes, his mannerisms are very much those of a stage actor, but at least he has some real menace.
