THE STAG ANTLER by Robert B. Appleton

1913. As the quiet English town of Leighton is rocked by several mysterious deaths, a stranger appears at the home of local Police Inspector Jonathan Greetham. The man’s description of an unearthly pursuer is puzzling. Before long, however, a bizarre chase unfolds with death in its wake, and Greetham is thrust headlong into a world of millionaires, revenge and supernatural horror.
