“I didn’t come here to be thanked or praised, Mrs. Allen,” said Myles, considerably embarrassed by the woman’s warmth of manner, “though I am much obliged to you for your kind words. I came to ask a favor of you.”

“Ask a thousand, sir, and if it lies in my power I’ll be only too glad of the chance to grant them all.”

“Well, perhaps you will find it hard to grant even the one I am going to ask,” said Myles, smiling. “It is that you will take this letter and contrive some means of getting it to your husband within the next three days. If you can do that you will indeed be conferring a favor, for I am in a great trouble that I believe your husband can help me out of.”

“And him with a price on his head!” exclaimed the woman, regarding the letter doubtfully, as though it might contain something dangerous to her husband’s safety.

“I know it,” said Myles, “and I realize that it may be very difficult, and perhaps impossible, to get this letter to him. I know though that you will undertake it for the sake of what I was able to do for little Bob, and because your husband would want you to if he knew of it.”

“Of course, sir, I’ll gladly take the letter and get it to him if I have the chance. I only hesitated because of the unlikelihood of having it in his hands within the time you named. I’m watched so close. There comes one of them now. Give me your letter quick and go your way, sir, before the spy suspects what we are talking of.”

“Very well, madam,” said Myles loud enough for the man who was sauntering slowly past the house and watching them closely to hear, “I am sorry I can’t sell you one of our sewing-machines on the installment plan. But here is a circular containing the address, and if you ever feel inclined to give the machine a trial, just drop us a postal.”

“Thank you, sir,” answered the woman, with a ready comprehension. “If I’m ever in a way to buy a machine I’ll give you the first chance to sell it to me.”

As she spoke she turned to go into the house, and Myles, again lifting his hat, bade her good afternoon and walked away.

He felt satisfied that he had done a good stroke of business, and was almost certain that, by some means, Mrs. Allen would contrive to have his letter conveyed to her husband within the time named.
