After some days of outward calm, came a ripple upon the surface of events.

It had been a dull, cloudy day, with occasional gusts of wind and rain; wind that chilled to the very marrow, and rain that froze as it fell.

The three men, Davlin, Percy and the Professor, had been constrained to abandon their customary morning walk, with cigar accompaniment, up and down the terrace. And the well-borers had been obliged to stop their work.

Mrs. Arthur had kept her room and her bed all day long, afflicted by a raging toothache. Strong was kept at her side, almost constantly applying hot water, laudanum and various other local applications. As the day advanced, the sufferer seemed growing worse; and when Madeline came in to administer consolation, and see if the woman were really ill, Cora sent for Dr. Le Guise, vowing she would have the tooth out, and every other one in her head, if the pain did not stop. But when the Professor arrived, her courage failed her. She drew back at the sight of the formidable forceps, saying that she would "try and endure it a little longer; it seemed a bit easier just then."

All this Madeline noted. Retiring from the room she signaled to Strong to follow her out. "What do you think of her?" questioned Madeline of the latter, as the door closed between them and Cora.

Strong looked dubious. "I really don't know what to think, Miss Payne," she said. "If it is shamming, it is the best I ever saw."

"True," answered Madeline; "I am at a loss. You had better apply some test, Strong, and—keep all your medicines out of her reach. Don't let her get any laudanum, or anything; and presently report to me. She must not be left alone, however; when I send Joliffe in, do you come to me."

Madeline passed on to her own room, and Strong returned to her patient.

When Joliffe went to her relief, Strong presented herself before Madeline, saying: "I can't think she is shamming, Miss Payne. I suggested a mustard blister, and she never made a murmur. I put it on awful strong, and she declared that it was nothing to the pain. When I took it off her cheek was red as flannel, and she wanted it put on again. She says it relieves her, and thinks if the pain don't come back she will sleep. I made sure of the bottles all the same," added Strong. "I have used a lot of chloroform on her, but of course some would evaporate." And she held up to view a half-filled chloroform vial.

She was right; full half an ounce had "evaporated," during the brief minute when she had stood in the hall to confer with Madeline.
