her a quick, understanding glance.

"You? Oh, no, Mrs. Burns. You do the prettiest work in the world, and the
most necessary."

"But yours is fine--wonderful."

"Not fine, nor wonderful. Dr. Burns's work is that. Mine is
just--supplementary."

"But absolutely essential. How many times has he told me what he has owed
you all these years for perfection of detail. He says he doubts if he
himself could secure such perfection if it all depended upon his care."

Amy Mathewson bent suddenly over a strange looking instrument, whose
parts she had been examining before putting them into the bag. Her fair
cheek flushed richly. "I am glad to give him the best I can do," she
said, quietly, yet Ellen could detect an odd little thrill in her voice.

Within herself Ellen understood the truth, which she had long ago
guessed. And with it came a fresh revelation. This was the reason why Amy
Mathewson could see, unmoved, the departure of Leaver, who had been so
closely thrown with her all that strange summer. With the deep loyalty of

"It's a serious handicap to a surgeon's best work," she asserted, "when
he has to do it at a home. With all my precautions, I can never feel so
sure of giving him perfect cleanliness of surroundings."

"You can, if any one can," Ellen said, feeling for the first time as she
spoke, a curious little twinge of envy of the one whom her husband had
long called, with affectionate familiarity, his "right-hand man."

Often as she had seen the two drive away together it seemed to her to-day
that she looked at them with new eyes. Just as Amy set out the closed
hand-bags, with a box and a bundle beside them, and donned hat and
driving-coat, the Green Imp came rushing up the road and stopped in front
of the house. Burns ran in, fired half a dozen rapid questions at Amy,
nodding his head with approval at her a
