1913德国悬疑
Peter Wilkes, tired of his connection with a disreputable secret order, requests its officers to release him from membership. He is released from further allegiance to the association upon the condition that he surrender to it any legacy that he might inherit. Shortly after this Wilkes learns that a firm of lawyers are advertising for him. In an interview with the lawyers, Wilkes is told that he is the next kin to a deceased nobleman and has inherited a sealed casket and a packet of papers. Wilkes finds the casket to contain valuable jewels and directions for locating additional treasure at Richmond Castle. Wilkes is now worried by the terms of his agreement with the order and decides to keep his wealth secret and ignore his promise. The attorney, although satisfied with the proofs which Wilkes produced, is nonetheless uneasy, and engages Grace Carter, a woman detective, to shadow Wilkes.
