Sherlock Holmes: The Musgrave Ritual

Family Tradition steeped in ancient ritual? Is it that simple? The Great Detective doesn't think so.
In this mystery, Sherlock Holmes recalls one of his earliest cases. The butler of Reginald Musgrave, one of Holmes' former schoolmates, has disappeared, and the local police can't solve the case. Holmes travels to the Musgrave estate and once there not only discovers the butler, but also finds out about the origin of the centuries-old Musgrave Ritual.
