Again I bowed my acknowledgments.
"And that's all you can tell me?" he added.
"I'm afraid that's all."
"Very well; thank you for that much," and he flicked the ashes from his cigar. "Now, I fear that I must leave you. I've a good deal of work to do, and you've opened up a very interesting line of speculation. I assure you that I've passed a very pleasant evening. I hope you've not found it tiresome?"
"Quite the contrary," I said heartily. "I've enjoyed myself immensely."
"Then I'll ask one last favor. My cab is at the door. I've no further use for it, and I beg you'll drive home in it."
I saw that he really wished it.
"Why, yes, certainly," I assented.
"Thank you," he said.
He took me down to the door, called the cab, and shook hands with me warmly.
