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.
