“A very wise precaution, Mrs. Markham,” said Doctor Hills; “and why did you leave your post, my man?”

“The butler told me of what had happened, and I wondered if I might be of any service down here. I left the butler in charge of the room while I came down to inquire.”

“Very thoughtful of you,” said Doctor Hills, with a nod of appreciation; “and while I hardly think so, we may have use for you before the night is over. I am expecting Doctor Leonard, the county physician, and until he comes I can do nothing. I am sure the room above is sufficiently guarded for the time being, so suppose you sit down here a few minutes and wait.”

Mr. Hunt chose to take a seat in the hall, just outside the library door, and thus added one more solemn presence to the quietly waiting group.

And now Doctor Hills had occasion to add another puzzling condition to those that had already confronted him.

Almost every one in the room was curiously affected by the appearance of this detective, or plain-clothes man, as he was called.

Schuyler Carleton gave a start, and his pale face became whiter yet.

Cicely Dupuy looked at him, and then turning her glance toward Mr. Hunt, whom she could see through the doorway, she favored the latter with a stare of such venomous hatred that Doctor Hills with difficulty repressed an exclamation.

Cicely’s big blue eyes roved from Hunt to Carleton and back again, and her little hands clenched as with a firm resolve of some sort in her mind; she seemed to brace herself for action.

Her hovering glances annoyed Carleton; he grew nervous and at last stared straight at her, when her own eyes dropped, and she blushed rosy red.
