Other Lives is one of those rare stories where the only sfnal elements are the Doctor and companions, and the Tardis. On a visit to the Great Exhibition (as promised originally by the Fifth Doctor at the start of Time Flight), everyone gets entangled in their own plotline - the Doctor embroiled in a case of mistaken identity, the Tardis arbitrarily wandering off with a couple of French tourists, C'rizz kidnapped by the proprietor of a freak show, and Charley rather gloriously hooking up with the Duke of Wellington, memorably portrayed by Ron Moody as a paragon of aged courtesy occasionally flipping into anti-revolutionary frothing. The plot doesn't really make a lot of sense, but it is enjoyable stuff. ( )
