“I am much obliged to you,” he said. “This is of interest to me.”
He stretched out his hand to the little wad of notes which Duson had left upon the table, but the cabdriver backed away.
“Beg pardon, sir,” he said. “You’ve given me plenty. The letter’s of no value to me. I came very near tearing it up, but for the peculiar colour pencil it’s written with. Kinder took my fancy, sir.”
“The letter is of value,” Mr. Sabin said. “It tells me much more than I hoped to discover. It is our good fortune.”
The man accepted the little roll of bills and departed. Mr. Sabin touched the bell.
“Duson, what time is it?”
“Nearly midnight, sir!”
“I will go to bed!”
“Very good, sir!”
“Mix me a sleeping draught, Duson. I need rest. See that I am not disturbed until ten o’clock to-morrow morning.”
