"I can guess," the Colonel answered. "To-morrow, at eleven o'clock," Wrayson declared, "I shall know who killed Morris Barnes." CHAPTER VI ONE THOUSAND POUNDS' REWARD But when the morrow came, and his visitor was shown into Wrayson's private office, he was not quite so sure about it. Mr. Bentham had not in the least the appearance of a murderer. Clean-shaven, a little slow in speech, quietly dressed, he resembled more than anything a country solicitor in moderate practice. He bowed in correct professional manner, and laid a brown paper parcel upon the table. "I believe," he said, "that I have the honour of addressing Mr. Wrayson?" Wrayson nodded a little curtly. "And you, I suppose," he remarked, "are the owner of the mysterious voice which summoned Morris Barnes to the Francis Hotel on the night of his murder?" "It was I who spoke to you," Mr. Bentham admitted. "Very well," Wrayson said, "I am glad to see you. It was obvious, from your message, that you knew of some danger which was threatening Morris Barnes that night. It is therefore only fair to presume that you are also aware of its source." "You go a little fast, sir," Mr. Bentham objected. "My presumption is a fair one," Wrayson declared. "You are perhaps aware of my unfortunate connection with this affair. If so, you will understand that I am particularly anxious to have it cleared up." "It is not at all certain that I can help you," his visitor said precisely. "It depends entirely upon yourself. Will you permit me to put my case before you?" "By all means," Wrayson answered. "Go ahead." Mr. Bentham took the chair towards which Wrayson had somewhat impatiently pointed, and unbuttoned his coat. It was obvious that he was not a person to be hurried. "In the first place, Mr. Wrayson," he said, "I must ask you distinctly to understand that I am not addressing you on my own account. I am a lawyer, and I am acting on behalf of a client." "Who is he?"
