"It would be useful," Wrayson admitted, "but, unfortunately, it is out of the question. Either he was deceiving you, or he was in possession of something which turned out far more valuable than he had imagined." "If so, where is it?" Mr. Sydney Barnes demanded. "If it was worth that to him, it may be to me." "Exactly," Wrayson remarked, "but the question of your brother's murder comes in there. People don't commit a crime like that for nothing, you know. If it was information which your brother had, it died with him. If it was documents, they were probably stolen by the person who killed him." "Come, that's cheerful," the young man declared ruefully. "If you're guessing right, where do I come in?" "I'm afraid you don't come in," Wrayson answered; "but remember I am only following out a surmise. Have you looked through your brother's papers carefully?" "I've gone through 'em all," Mr. Sydney Barnes answered, "but, of course, I was looking for scrip or a memorandum of investments, or something of that sort. Perhaps if a clever chap like you were to go through them, you might come across a clue." "It seems hard to believe that he shouldn't have left something of the sort behind him," Wrayson answered. "It might be only an address, or a name, or anything." "Will you come round with me and see?" Mr. Barnes demanded eagerly. "It wouldn't take you long. You're welcome to see everything there is there." Wrayson called for the bill. "Very well," he said, "we will take a hansom round there at once." They left the place a few minutes later, and drove to Battersea. "There's a quarter to run, the landlord says, so I'm staying here," Barnes explained, as he unlocked the front door. "I can't afford a servant or anything of that sort of course, but I shall just sleep here." The rooms had a ghostly and unkempt appearance. The atmosphere of the sitting-room was stuffy and redolent of stale tobacco smoke. Wrayson's first action was to throw open the window. "There isn't a sign of a paper anywhere, except in that desk," the young man remarked. "You'll find things in a mess, but whatever was there is there now. I've destroyed nothing."
