Curate's Egg, 29 August 2005
Author: Paul English from Ireland

'An Echo Of Theresa', the fourth episode of series one is one of Thriller's less successful stories. The narrative is somewhat confusing with a number of unclear twists. Nevertheless it is never dull and is particularly worth watching for Dinsdale Linden's performance as the flamboyant and gregarious detective, Matthew Earp.

The basic premise is as follows: Brad and Suzy Hunter visit England on a sightseeing tour. Shortly after arrival Brad begins to display some alarming behavioural traits. He insists on referring to Suzy as Theresa in front of a prospective business acquaintance and subsequently throws a fit of inexplicable rage with the same individual.

Gradually he suffers a form of breakdown which manifests itself in total confusion about his identity - he later goes on to believe that he is Englishman called Charles Merrow.

Paul Burke and Polly Bergen are competent in their roles as the Hunters while the conclusion of the story is quite clever and is not easily guessed.

However it pales in quality to some of the subsequent episodes and is best described as the veritable curate's egg - good in parts.
