Unnatural Death (audiobook)

This is the third book in the Lord Peter Wimsey mystery series.* As the story opens, a country doctor is telling Lord Peter Wimsey about the Unnatural Death of one of his patients. He’s convinced she was murdered, but powerless to act. To begin with, she would in any case have died within a few months. Moreover, the medical evidence clearly indicated the cause of death as heart failure, which was only to be expected. Intrigued, Lord Peter looks into the matter, supported – as usual – by his friend Chief Inspector Parker of Scotland Yard, and his valet, Bunter (both recurring characters in the Lord Peter Wimsey mystery series).
