one part of the wall gave forth a more hollow and deeper echo; he eagerly advanced, and with the quickness of perception that no one but a prisoner possesses, saw that there, in all probability, the opening must be.
However, he, like Caesar Borgia, knew the value of time; and, in order to avoid fruitless toil, he sounded all the other walls with his pickaxe, struck the earth with the butt of his gun, and finding nothing that appeared suspicious, returned to that part of the wall whence issued the consoling sound he had before heard.
He again struck it, and with greater force. Then a singular thing occurred. As he struck the wall, pieces of stucco similar to that used in the ground work of arabesques broke off, and fell to the ground in flakes, exposing a large white stone. The aperture of the rock had been closed with stones, then this stucco had been applied, and painted to imitate granite. Dantès struck with the sharp end of his pickaxe, which entered someway between the interstices.
