This episode of the Thriller series, although well-written and fairly well-cast, is a bit of a mish-mash really, not quite knowing what it is.
The story starts with Americans in London, Brad and Suzy Hunter (Paul Burke and Polly Bergen). He's rich and looking to close a deal with a fellow businessman, but keeps lapsing into strange outbursts about someone named Theresa - a name by which he first introduces his wife.
Clearly Hunter is losing his mind - or is he? This tale heads towards a tale of spies and brainwashing very quickly and although there are some nice touches (one character (Vernon Dobtcheff) is very Blofeld-like with his cat; London locations are used well), it takes a while to get going, only coming to life really with the introduction of the character of private detective Matthew Earp ('with more than a touch of Wyatt', played by Dinsdale Landen), who steals the show conclusively but unbalances the tone of the episode somewhat.
However Earp is such a fun character (and would return in another Thriller instalment two years later) I can't complain, and he does solves the mystery with some eccentricity and a touch of bravado. It's such a pity that the Hunters are played so flatly and suffer in comparison, and the 'An Echo of Theresa' doesn't really have a focus for where the story is going.
