"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."
