Engaging Mystery
7 September 2013 | by Theo RobertsonSee all my reviews

Ruth is a journalist for a female magazine and gets hold of a new miracle diet from an organisation calling itself Think Thin . After the death of a friend called Ben in a car crash one of the funeral directors Andrew who buried Ben visits Ruth and tells her there's something amiss at work and also something that ties in with the Think Thin organisation

This is a fairly efficient episode of THE HAMMER HOUSE OF HORROR . It's not exactly ground breaking but in its defence it doesn't contain any supernatural elements which makes it fairly credible . Okay it's not realistic drama but as a standard mystery thriller it just about works . The main problem is that once you know what is at the centre of the mystery involving the funeral directors and Think Thin the cat is let out of the bag and the impact is gone on repeat viewings . It also might work better if there's a fashionable diet in the news . The 13th Reunion was broadcast a few years before the F plan diet and if the cult of dieting had been in the news perhaps this episode might have been better remembered

One interesting aspect is the casting of a couple of Scottish actors in pivotal roles . One is James Cosmo who made a career playing ginger haired Scottish hard men and it's amusing seeing him reducing a dieter to tears " Have ya looked in the mirror recently ? No wonder your husband is working late " . The other actor is Gerard Kelly who would find fame in Scotland playing Willie Melvin in the long running Scottish sit com CITY LIGHTS and he gives a very understated performance here
