"And we know the rest," said Rupert rising. "Tidman gave it to Dr. Forge, and he gave it to you--or rather you caused it to be taken from him." "No," said the Mandarin, "that is not true. I never saw the fan till now. All these years I have never set eyes on it." "But Dr. Forge said--" "Whatever he said he speaks falsely," said Lo-Keong, "but it is growing late, Mr. Ainsleigh, and I see that your wife is weary. Let us retire and I shall tell you the rest of the story to-morrow. But before I go to rest," added the Mandarin decidedly, "I must assure myself that the packet is still in the trunk of the third tree." Rupert was quite ready and lighted the lantern. The two men went to the Abbey into the pitchy darkness, and walked to the third tree near the bare spot. Lo-Keong who seemed to be able to see in the dark like a cat looked round, and laid his finger on a huge oak. "This is the tree," said he confidently. "But I can't very well see," said Rupert, "from which side do you count?" "From the left to right," explained the mandarin, "in these robes, Mr. Ainsleigh, I cannot climb the tree, will you please to do so. You will find the hollow trunk and the line. Pull it up: the papers will be at the end. Bring them to me if you please." So speaking Lo-Keong took the light and Rupert although in thin evening dress began to climb the tree. Luckily it was not difficult as the branches hung low, but it was disagreeable on account of the dripping wet. Every movement shook down much moisture. However, the active young man disappeared in the foliage and then felt round. He could not see, and came down to get the lantern, which the Chinaman passed to him. Then he found that the trunk of the tree was broken off, amidst the thick branches, and that the centre was hollow. He espied a rusty thin chain, and pulled it up. At the end there was a small box, which he brought down. With an exclamation of joy Lo-Keong took it. It opened easily in his hand. "Gone," cried the Marquis in a voice of anguish. He spoke truly. The box was empty. CHAPTER XXI WHO IS GUILTY? Next morning at the early hour of nine o'clock Orlando Rodgers drove up to Royabay filled with curiosity. He had received Rupert's letter which summoned him to come down on matters connected with the murder, and he was eager to learn details. Rodgers himself, had been unlucky. He had traced The Stormy Petrel to the Thames near Rotherhithe, and had learned from the Captain that two Chinamen had hired the boat for a couple of days. They went down to Marport and had gone ashore early in the evening. They came on board again after midnight, and then had requested to be put ashore at Rotherhithe. The Captain confessed that he had been paid well for the job, and thought--with a wink--that there was no chance of his knowing his employers again.
