'Death To Sister Mary' was aired as part of Thriller's outstanding third season and once again sees Robert Powell in the leading role - albeit a very different character to the one played in the series opening story 'Lady Killer'.

The story is based around a soap opera called Saints and Sinners of which Powell's introspective Mr Rook is an avid fan. His attention is particularly driven towards Penny Stacey who plays the part of Sister Mary (played by Jennie Linden) and he quickly makes himself known to her by visiting the studio. He wastes no time by informing Sister Mary that he wishes to set up a fanclub dedicated to her and to the viewer's surprise she has no hesitation in supplying him with her home address.

It is obvious from the outset that Rook is a far more harmful individual than his meek demeanour suggests. A series of unpleasant accidents take place involving the soap's other stars and it is compelling to watch the deluded Rook as he relentlessly pursues his obsession.

George Maharis gives a good account of himself as the protective Mark Fields who gradually discovers that Penny may be in more danger than she realises.

A fine effort.
