ut upon its castors.
She soon guessed that Blake perceived that he was being watched, and
she imagined how he must be smiling up his sleeve at her simplicity.
Had the matters at stake not been so grave, had she been more certain
of the issue, she might have put her own sleeve to a similar purpose.

In the meantime, as far as she could do so without exciting suspicion,
she kept close watch upon Blake. It had occurred to her that there
was a chance that he had an unknown accomplice whose discovery would
make the gaining of the rest of the evidence a simple matter. There
was a chance that he might let slip some revealing action. At any
rate, till Mr. Manning came, her role was to watch with unsleeping eye
for developments. Her office window commanded the entrance to Blake's
suite of rooms, and no one went up by day whom she did not see. Her
bedroom commanded Blake's house and grounds, and every night she sat

suspicious visitors, or possible suspicious movements on the part of
Blake.

Also she did not forget Doctor Sherman. On the day of her departure
for New York, she had called upon Doctor Sherman, and in the privacy
of his study had charged him with playing a guilty part in Blake's
conspiracy. She had been urged to this course by the slender chance

court-room, he might break down and confess. But Doctor Sherman had
denied her charge and had clung to the story he had told upon the
witness stand. Since Katherine had counted but little on this chance,
she had gone away but little disappointed.

But she did not now let up upon the young minister. Regular
attendance at church had of late years not been one of Katherine's
virtues, but after her return it was remarked that she did not miss a
single service at which Doctor Sherman spoke. She always tried to sit
in the very centre of his vision, seeking to keep ever before his
mind, while he preached God's word, the sin he had committed against
God's law and man's. He visibly grew more pale, more thin, more
distraught. The changes inspired his congregation with concern; they
began to talk of overwork, of the danger of a breakdown; and seeing
the dire possibility of losing so popular and pew-filling a pastor,
they began to urge upon him the need of a long vacation.

Katherine could not but also give attention to the campaign, since it
