Lorian threw down his pencil and began to reload his pipe. "Let us consider possible meanings to the original words," he said. "Do you know of anything in the neighbourhood which might answer to the description of a 'strypped tree'?" I shook my head. "What has occasioned your sudden interest in the thing?" I asked wearily. "It is a long story," he replied; "and I have an idea that there's no time to be lost in solving the Riddle!" However, even Lorian's enthusiasm flagged at last. We were forced to admit ourselves hopelessly beaten by the Riddle. I went to my own room feeling thoroughly tired. But I was not destined to sleep long. A few minutes after closing my eyes (or so it seemed), came a clamouring at the door. I stumbled sleepily out of bed, and, slipping on my dressing-gown, admitted Lorian. Colonel Reynor stood immediately behind him. "Most extraordinary business!" began the latter breathlessly. "Sybil had--_you_ tell him, Harry!" "Well," said Lorian, "it is not unexpected! Listen: Sybil woke up a while ago, with the idea that she had forgotten something or lost something--you know the frame of mind! She went to her dressing-table and found the family ring missing!" "_The_ ring!" burst in the Colonel excitedly. "Amazing!" "She remembered having taken it off, during the evening, to--er--to put another one on! But she was unable to recall having replaced it. She determined to run down and see if she had left it upon the seat in the corner of the library. Well, she went downstairs in her dressing-gown, and, carrying a candle, very quietly, in order to wake no one, crossed to the library and searched unavailingly. She heard a faint noise outside in the hall." Lorian paused. Felix Hulme had joined the party. "What's the disturbance?" he asked. "Oh," said Lorian, turning to him, "it's about Sybil. She was down in the library a while ago to look for something, and heard a sort of grating sound out in the hall. She came out, and almost fell over an iron-bound chest, about a foot and a half long, which stood near the bottom of the staircase!" "Good heavens, Lorian!" I cried, "how had it come there?" "Sybil says," he resumed, "that she could not believe her eyes. She stooped to examine the thing ... and with a thrill of horror saw it to be roughly marked _with a skull and cross-bones_!" "My dear Lorian," said Hulme, "are you certain that Miss Reynor was awake?" "She woke _us_ quickly enough!" interrupted the Colonel. "Poor girl, she was shaking dreadfully. Thought it was a supernatural appearance. She's with her mother now." "But the box!" I cried. "Where is the box?" "That's the mystery," answered Colonel Reynor. "I was downstairs two minutes later, and there was nothing of the kind to be seen! Has our Ragstaff ghost started walking again, I wonder? You ought to know, Hulme; you're in the Turret Room--that is the authentic haunted chamber!"
