yes had fallen on her, they remained there for several minutes.

Why?

Perhaps because she sat so unnaturally still. In all the time he stared
at her simple bonnet and decently clothed shoulders, the silhouette she
made against the silver band of the river did not change by an iota. He
had been agaze upon the landscape too, but he was sure that he had not
sat as still as this, and when, after an interval during which he had
turned to see what kind of man it was who had spoken so vigorously, he
wheeled back into place and glanced out again through his window, she was
there yet, hat, shoulders and all, immovable as an image and almost as
rigid.

Well, and what of it? There was surely nothing very remarkable in so
commonplace a fact; yet during the ensuing half-hour, during which he
gave, or tried to give, the greater part of his attention to the
political talk which followed the statements he had heard made in regard
to the needs of a certain factory, his eye would turn riverward from time
to time and always with a view to see if this woman had moved. And not
once did he detect the least change in her attitude.

"She will sit there all night," he muttered to himself; and after a while
his curiosity mounted to such a pitch that he got up and went out on the
piazza for one of his short strolls.

HE REMEMBERS

Just an ordinary woman, lost in a dream of some kind while awaiting her
departure on an out-going train!--or such was Detective Gryce's
conclusion as he hobbled slowly past her.

Why should he give her a moment's thought? Yet he did. He noticed her
dress and the way she held her hands, and the fact, not suspected before,
that she was not looking out at the landscape outspread before her eyes,
but down into her lap at her own hands clasped together in an unnaturally
tight grip. Then he straightway forgot her in the thought of that other
woman whose track he was following with such poor promise of success.
Madame Duclos' image was in his mind as plainly as if she sat before him
in place of this chance passenger. He knew the sort of hat she would wear
(or thought he did). He also knew the color of her dress. Had he not been
shown the piece of goods from which it had been taken? And had he not
understood her choice, bizarre as it was, and for this very reason, that
it was bizarre? Being a woman of subtle mind, she would reason that
since the police were seeking one of plain exterior and simple dress,
