Joseph Sheridan Le Fanu 
Wylder’s Hand 

First published in 1864, Wylder’s Hand was one of J. Sheridan Le Fanu’s most popular novels, but has been largely neglected, until now. It is a nerve-jangling tale of jealousy and murder, for fans of the grisly and gripping. Synopsis: The Wylders and the Brandons share a history of intermarriage, bitter rivalry, villainy, and madness. The wedding of Mark Wylder to his rich and beautiful cousin, Dorcas Brandon, was to inaugurate a harmonious new era at Brandon Hall but as the ceremony draws near, Mark disappears without trace, leaving Dorcas in shock, and the assembled family in a state of severe agitation. When Mark’s letters arrive back at the Hall, postmarked from Europe, the sinister figure of Captain Stanley Lake emerges from the wings to claim Dorcas as his own. (Goodreads)
