Sherlock Holmes and the Zombie Affair

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.

Sherlock Holmes and Dr Watson are called back to the scene of the Case of the Dog which Did Not Bark, to investigate reports of a litch, a risen corpse or zombie, in the area.
In the course of their investigation they meet danger and are involved in mysterious events. They see death, true love(perhaps), and a great mystery revealed in an idiosyncratic way by the well meant actions of Dr Watson.
