The Doctor and his friends have had many questions about Kamelion – and now they’re about to find out that ignorance may have been bliss.

This is the final story in the Kamelion trilogy – and, from the way in which it concludes, possibly the final story to feature the Doctor’s robot friend… at least until Alan Barnes needs to exorcise more of his King’s Demons (that’ll make sense when you listen to the extras). Jonathan Morris’ script uses the chameleonic nature of Kamelion to its fullest extent, allowing there to be multiple characters that happen to look (or more importantly sound) like our four regulars.

Jon Culshaw isn’t confined to just the normal Kamelion for this story, and he clearly revels in the chance to be one of the bad guys – there are hints in his performance of some other classic Who villains, something he confirms in the extras. Morris fleshes out the back story for the race, and there are certainly elements to it that make you feel that Tegan’s initial reaction to Kamelion might not have been as far off the mark as you’d expect.

It’s effectively a four-hander for the majority of the time, and Ken Bentley brings his stage experience to bear, ensuring that the pace never flags.

Verdict: An interesting experiment comes to a close with a suitably twisting tale of identities. 8/10
