A Dangerous Call, 2 February 2005
Author: Alan Briscoe from United Kingdom

Dave Adams is an American actor living in England. His career is going nowhere, he is broke and it looks like it might be time for him to return home. Then a telephone call changes matters dramatically. A distraught woman, Helen Curry, has misdialled, believing that she has got through to a psychiatrist. At first Dave tries to explain her mistake but she is too upset to listen. He then hits upon the illegal, immoral - but potentially very lucrative plan - of impersonating the psychiatrist.

Dave goes through with this con, to the disgust of his flatmate Tim. He goes to see Helen and even gives her sweeteners claiming that they are tranquilisers. Helen explains that she has terrible nightmares involving her killing a man. Dave thinks these are just neurotic ramblings and can't believe his luck. Meanwhile he starts an affair with Helen's attractive and far more confident and composed sister, Ann.

However maybe things are not as simple as they seem. Dave discovers that a man sent to the Curry's house has been missing although his hat is still there. Matters may be rather more dangerous than they seem.

This is one of the final installments of "Thriller" and it is very popular among fans. However it has never been one of my favourites. Undoubtedly it is very professionally done. For me though it doesn't seize the imagination and seems somewhat low-key. The acting performances are very sound. Gary Collins, making his third guest appearance as Dave, is excellent,. He is given very good support by Cavan Kendall as his principled flatmate Tim. However there is something missing.

This is demonstrated by the ending. The conclusion involves a very clever twist. In other circumstances it would be very powerful but here it doesn't make the same impact. However I would stress that other viewers have been very impressed and would recommend watching the episode to make up your own mind.
