Juve did not budge.

Certainly there was the window at the other end of the room looking on to the Esplanade des Invalides. Curtains were drawn across the window, but Juve did not fear to see his adversary escape in that direction: he knew—and he alone knew it—that between this window and the curtains there was an obstacle—someone."...
