It’s been interesting rereading a few Jane Marple books after I so recently viewed the television versions, because although I have known the identity of each murderer, I’ve been better able to judge how fair Christie is playing. That is, are there clues to the solution? In The Mirror Crack’d there are.
The villagers of St. Mary Mead are agog to hear that the famous actress, Marina Gregg, has purchased Gossington Hall (the site of The Body in the Library) and will be hosting the local fête. Miss Marple’s friend Mrs. Bantry, who used to own the house, will be a special guest.
At home, Miss Marple is a bit unhappy. She is no longer allowed to garden, and her doctor thinks she shouldn’t live alone. The solution is the kind but obnoxious Mrs. Knight, who talks in the plural and hovers and doesn’t listen to Miss Marple. One day Miss Marple sends her out shopping so she can escape and goes to investigate the new housing development. She has a fall and is helped by Heather Badcock, a foolish woman who doesn’t consider how her actions affect others.
At the fête, just after Heather has introduced herself to Marina Gregg and is again telling her how she met her, her drink is spilled. Marina gives Heather her own, and after Heather drinks it, she quickly dies. It is poisoned, but was the victim intended to be Heather or Marina? Neither woman seems to have serious enemies.
I think that this novel has one of the most powerful endings of Christie’s novels. You’ll also be happy to know that Miss Marple finds a way to rid herself of Mrs. Knight.
