The Courtesy of Death — Geoffrey Household

A retired engineer in rural Britain finds himself caught up in the murderous machinations of an ancient pagan blood cult

A former British mining engineer, Yarrow is hoping to start over in the English countryside as the owner and operator of a small combination inn and garage. But while staying the night at a prospective property near Avalon, he is awakened by a loud pounding at the door -- and opens it to discover a distraught, seemingly mad visitor babbling on about all manner of incomprehensible concerns. Intrigued by the engaging lunatic Barnabas Fosworthy and unable to turn a deaf ear to his desperate pleas for help in finding a missing young woman, the all-too-good-hearted Yarrow inadvertently invites grave danger into his life. Fosworthy is part of a circle of crazed fanatics tied to ancient and terrifying beliefs -- and before Yarrow realizes what he has gotten himself into, he finds himself trapped in an underground cavern, the prisoner of determined cultists who view murder as a gift. Now he must pursue every conceivable path toward escape -- or consign himself a horrifying end.
 
Chilling, surprising, and utterly riveting, The Courtesy of Death is a wildly imaginative suspense yarn that blends intrigue with a touch of the otherworldly. Filled with action and unforeseen twists, this is the bravura work of a master storyteller operating at the very top of his game.
