My 33rd Companion Chronicle (a little out of sequence) and one that I am very impressed with. Frazer Hines engagingly tells a story told after The War Games (the final Troughton story and one where McCrimmon ultimately has his mind erased). It would be spoilers to say how this works, but it partly enables a story to be told on more than one level because a paradox is involved and ultimately resolved. It involves an arguably less well remembered Monarch and related pivotal events.
The story is very true to Jamie McCrimmon's character and the overall product strongly highlights a potential dual interpretation in the series title: "Companion Chronicles". It chronicles an adventure with far more involvement from the companion, and it is a very worthwhile companion to the Doctor Who 'television chronicles'.
I was quite amazed as just how good Frazer Hines can do Patrick Troughton's voice and his character's mannerisms. You really can enjoy their double act despite the same actor. There is also a second performer on the disc who does two completely different roles and again you would not notice.
A very welcome addition to the range, giving us something quite special to the overall Doctor Who canon, particularly with the ending.
