She hesitated; she knew that her father would not permit the vague generality that Eaton was "a gentleman." "Exactly what do you mean, Father?"

"I don't mean, certainly, to ask whether he knows which fork to use at table or enough to keep his napkin on his knee; but you have talked with him, been with him—both on the train and here: have you been able to determine what sort of people he has been accustomed to mix with? Have his friends been business men? Professional men? Society people?"

The deep and unconcealed note of trouble in her father's voice startled her, in her familiarity with every tone and every expression. She answered his question: "I don't know, Father."

"I want you to find out."

"In what way?"

"You must find a way. I shall tell Avery to help." He thought for several moments, while she stood waiting. "We must have that motor and the men in it traced, of course. Harriet, there are certain matters—correspondence—which Avery has been looking after for me; do you know what correspondence I mean?"

"Yes, Father."

"I would rather not have Avery bothered with it just now; I want him to give his whole attention to this present inquiry. You yourself will assume charge of the correspondence of which I speak, Daughter."

"Yes, Father. Do you want anything else now?"

"Not of you; send Avery to me."
