with seven fingers. Malcolm then finds the missing lamps in Margaret's bedroom. Concerned for Margaret, Malcolm tells Corbeck everything that has happened up until his arrival, and Corbeck gives Malcolm a mysterious book to read. The book tells the story of Nicholas van Huyn, a Dutch explorer who travelled to the Valley of the Sorcerer to explore the tomb of a mysterious Egyptian queen, Tera. In the tomb, he finds a sarcophagus and a mummy hand with seven fingers, adorned with a ruby ring with seven points that look like stars. Corbeck tells Malcolm that, years ago, he and Trelawny travelled to Egypt to search for the tomb where the sarcophagus lies. They find the tomb and discover that the mummy's wrist was coated with fresh dried blood. The hieroglyphics on the wall led Corbeck and Trelawny to believe that the mummy was possessed with some sort of black magic and that Queen Tera had immense power over the Upper and Lower Worlds. The hieroglyphics seemed to indicate that Tera planned to return from the dead. They took the sarcophagus from the tomb and left, only to be robbed of the mummy during a storm by their Arab guides. Trelawny suggested that they return to the tomb, where they found the mummy and the three Arabs, murdered. During their time in the tomb, they were put under some trance and recovered three days later to find that Trelawny's wife had died in childbirth, but Margaret survived. Sixteen years passed before Trelawny contacted Corbeck, frantic because he believed that the lamps they saw in the tomb, when arranged in a specific shape, would make the coffer open and would possibly be the key to Tera's resurrection. Corbeck's story is interrupted by Trelawny's revival. He embraces his daughter and joyfully approves Malcolm's courtship. Dolan and the police depart, glad to escape from the mystery, and Trelawny gathers the remaining inhabitants of the house to explain his Great Experiment. He describes how powerful Queen Tera was and explains that her spirit has been residing in the mummy cat in Trelawny's room, waiting to be reunited with its human form. Trelawny believes that the coffer, when opened by the proper formation of the lamps, will release some sort of magic that will revive the mummy and bring Tera's spirit to life. Trelawny's attack was the attempt of Tera's astral body—the mummy cat—to remove the
