Strange deaths have occurred at the Castle Inn. In total three unexplained fatalities. The last death was the one of Archibald Wentworth. The well-to-do sleuth John Bell is investigating. Despite being strongly discouraged, Bell sleeps in the haunted chamber and thereby solves the supernatural mystery and explains it with science and common sense.
