Unnatural Death

Lord Peter Wimsey undertakes an investigation into the death of an elderly woman who had succumbed to cancer three years earlier, and whose death profoundly affected the medical career of the doctor who had been entrusted with her care.

Putting his associate, the indomitable Miss Climpson, to work undercover in the victim's home town, Lord Peter leaves no stone unturned in his search for a person with the motive and the opportunity to commit murder.
