Wychford Poisoning Case

Mrs Bentley has been arrested for murder. The evidence is overwhelming: arsenic she extracted from fly papers was in her husband's medicine, his food and his lemonade, and her crimes are being plastered across the newspapers. Even her lawyers believe she is guilty. But Roger Sheringham, the brilliant but outspoken young novelist, is convinced that there is 'too much evidence' against Mrs Bentley and sets out to prove her innocence.
