The Moving Finger written by Agatha Christie performed by Joan Hickson on CD (Unabridged)

Of poison pens and poisoning: a gripping Miss Marple mystery. Lymstock is a town with more than its share of shameful secrets – a town where even a sudden outbreak of anonymous hate-mail causes only a minor stir. But all that changes when one of the recipients, Mrs Symmington, commits suicide.

Her final note said ‘I can’t go on’. Only Miss Marple questions the coroner’s verdict of suicide. Was this the work of a poison-pen? Or of a poisoner?
