Wrayson had pulled himself together with an effort. "I presume," he said, "from your frequent reiteration, that I may take this as being to some extent a personal offer. If so, let me assure you, sir, that so far as I am concerned I know nothing whatever of any papers or other belongings which were in the possession of my late neighbour. I have never seen or heard of any. I do not even know why you should have come to me at all." "I came to you," Mr. Bentham said, "because I was very well aware that, for some reason or other, your evidence at the inquest was not quite as comprehensive as it might have been." "Then, for Heaven's sake, tell me all that you know!" Wrayson exclaimed. "Take my word for it, I know nothing of this document or paper. I have neither seen it nor heard of it. I know nothing whatever of the man or his affairs. I can't help you. I would if I could. On the other hand, you can throw some light upon the motive for the crime. Who is your client? Let me go and see him for myself." Mr. Bentham rose to his feet, and began slowly to draw on his gloves. "Mr. Wrayson," he said quietly, "I am disappointed with the result of my visit to you. I admit it frankly. You are either an extremely ingenuous person, or a good deal too clever for me. In either case, if you will not treat with me, I need not waste your time." Wrayson moved to the door and stood with his back to it. "I am not at all sure," he said, "that I am justified in letting you go like this. You are in possession of information which would be invaluable to the police in their search for the murderer of Morris Barnes." Mr. Bentham smiled coldly. "And are not you," he remarked, "in the same fortunate position--with the unfortunate exception, perhaps, of having already given your testimony? Of the two, if disclosures had to be made, I think that I should prefer my own position." Wrayson remained where he was. "I am inclined," he said, "to risk it. At least you would be compelled to disclose your client's name." Mr. Bentham visibly flinched. He recovered himself almost immediately, but the shadow of fear had rested for a moment, at any rate, upon his impassive features. "I am entirely at your service," he said coldly. "My client has at least not broken the laws of his country." Wrayson stood away from the door. "You can go," he said shortly, "if you will leave me your address." Mr. Bentham bowed. "I regret that I have no card with me," he said, "but I have an office, a single room only, in number 8, Paper Buildings, Adelphi. If you should happen to come across--that document--" Wrayson held open the door. "If I should come to see you," he said, "it will be on other business." * * * * *
