“Yes?  Then your business with me is—­ ?  Perhaps you desire board?” and she smiled; first at him and then at me.

“No; we do not wish board,” was the quiet reply.  “We come to see you on business.”

“And what is it?”

“We would like to see you privately.”

“Certainly.  Pray take a seat.  I will close the doors.”

She shut the folding doors leading to the sitting room, and then the door to the hall.

“Now I am quite at your service,” she said, and peered at us rather sharply.

There was an awkward pause for a moment, and then Mr. Harrison went on bluntly:—­

“Has Mr. Aaron Woodward or Chris Holtzmann been here since yesterday, madam?”

Mrs. Mitts started at the mention of the two names.  Then she recovered herself.

“Whom did you say, sir?” she queried innocently.

Mr. Harrison repeated his question.

“Why, I really haven’t heard of those two gentlemen in so long a time I’ve nearly forgotten them,” she said sweetly.

“They weren’t here yesterday?” I put in.

“No.”  And this time her tone was a trifle cold.

“Do you expect them to-day?” I went on.

“No, I don’t.”  She paused a second.  “Is that all you wish to know?”

“No, ma’am,” I replied promptly.  “There is a good deal more I wish to know.”

“Who are you, if I may ask?”

“My name is Strong.”

She looked puzzled for a moment.

“I don’t recognize the name,” she said, and then she suddenly turned pale.

“I am the son of Carson Strong, who was sent to prison for alleged forgery and the passing of worthless checks,” I continued.  “I suppose you remember the case.”

“Har—­ hardly,” she faltered.  “I—­ I heard something of it, but not the particulars.”

“That is strange, when you were so interested in it.”

“I?” she repeated, in pretended surprise.

“Yes, madam,” said Mr. Harrison.  “You were very much interested.”

“Who says so?”

“I say so,” said I.

“You!  You are only a boy.”

“I suppose I am, but that doesn’t make any difference.  You know all about the great wrong that has been done, and—­”

“It is false!  I know nothing!” she cried in anger.

“You know all, and we want you to tell as all you know before we leave this house.”

Mrs. Agatha Mitts arose in a passion.

“I want you to get out of my house at once!” she ejaculated.  “I won’t stand your presence here another minute.”

“Excuse me, madam; not so fast,” said Mr. Harrison, calmly.  “My young friend Strong is quite right in what he says.”

“I don’t care what you think about it,” she snapped.

“Oh, yes, you do.  Perhaps you don’t know who I am,” went on my Western friend, deliberately.

The sly insinuation had its effect.  Evidently the woman had a swift vision of a detective in citizens’ clothes before her mind’s eye.
