An appalling version
This story was televised on the BBC in the late 70s with a magnificent
cast, headed by Hywel Bennett and Cheryl Campbell. It remained faithful
to the book, maintaining the twists and tangles right to the end. As a
magnificent reproduction of the atmosphere of 1920's Devon, it was a
superb example. A fine example of the successful televising of a very
classy British thriller, so popular in the first half of the 20th
century.
This version is a travesty and an abomination. It makes material
alterations to the original plot, introduces unnecessary characters and
plays down the significance of others. All this version does is try to
introduce its own angles to a story that patently does not need it. If
it ain't broke, don't fix it.
Avoid it like botulism.
