Thank you to Nancy Weitendorf for suggesting this story and for sending me her book all across the wide Atlantic at not inconsiderable cost!
On a mist-shrouded night in March, two brave souls, Muriel Fisher and Scotty McCormack, dare to confront the malevolent secrets of a forsaken house with a history steeped in death. As they step into its decaying halls, the oppressive silence of the house breathes life into shadows, whispering of the dark fates that have befallen all who entered before them. As midnight looms, they will face an unspeakable terror that blurs the line between the living and the dead, in a chilling tale where the past refuses to rest.
