67. Frontier in Space

An era comes to an end with the last story featuring Roger Delgado as The Master. With Roger dying in a tragic car accident after this episode aired, Frontier in Space is the final battle between Jon Pertwee's Doctor and Roger's Master. The story sums up quite well their relationship. Political maneuvering, power plays, pitting two sides against each other, and the Master impersonating a diplomat. It's a fun space drama romp!

We also are introduced to the Draconians, an alien reptile like species akin to ancient Japanese samurai. Jon Pertwee was frequently quoted as saying the Draconians were his favorite alien because you could see their face. I am surprised that the Draconians haven't been brought back in the new series, but the new Silurians have in many ways become the new Draconians.

The surprise twist at the end is something we've never seen before and we haven't seen again since- the Master and the Daleks joining forces! If only for a few brief moments, it's a great moment. This dovetails into the next story for another joyous Dalek romp. But after a great presence as the Master, Roger fades away into the darkness, and we say good night sweet Prince. Farewell Master.
