It must be observed that as a separate passage led to the first floor, in which d'Artagnan lodged, those who called on him were exempted from this detention.
Besides, nobody came thither but the three Musketeers; they had all been engaged in earnest search and inquiries, but had discovered nothing.
Athos had even gone so far as to question M.de Treville--a thing which, considering the habitual reticence of the worthy Musketeer, had very much astonished his captain.

But M.de Treville knew nothing, except that the last time he had seen the cardinal, the king, and the queen, the cardinal looked very thoughtful, the king uneasy, and the redness of the queen's eyes donated that she had been sleepless or tearful.

But this last circumstance was not striking, as the queen since her marriage had slept badly and wept much.
M.de Treville requested Athos, whatever might happen, to be observant of his duty to the king, but particularly to the queen, begging him to convey his desires to his comrades.
As to d'Artagnan, he did not budge from his apartment.

He converted his chamber into an observatory.

From his windows he saw all the visitors who were caught.
