The cause of death isn't a poison or a weapon, but a systemic environmental cover-up. Unnatural Causes by P.D. James – Book review

The title typically refers to a death resulting from external factors like accidents, homicides, or social conditions rather than biological aging.

The victim had many literary rivals, and nearly everyone in his inner circle has a motive related to a missing inheritance.

The "unnatural" circumstances of the death hide a natural medical secret that the killer exploited.

Powerful political figures want the case closed to avoid a public scandal.

A world-class forensic pathologist is tasked with re-examining a high-profile case that the public has already written off as a natural tragedy. Through 23,000 autopsies, he has learned that the body never lies, even when the evidence is microscopic.
