Agatha

In 1926, when her marriage with a stiff colonel has run down, Agatha Christie mysteriously vanishes. In the middle of both police and public investigation after the famous writer, an American journalist finds her in a Harrogate spa-hotel where, under a pseudonym, she prepares an elaborate revenge against her husband's lover.

Straightly fictitious solution to a famous and still unsolved real-life disappearance, with more attention to gleaming period detail and chillingly murky atmosphere than to suspense or credibility, while Redgrave's finely sensible portrait is downed by the somewhat strained and out-of-place casting of Hoffman as love interest. Eventually, this glossily romantic thriller has its own fascinations and is always well worth looking at, but the mystery is simply not as startling or revealing as one would expect from the Grande Dame of whodunit.
