To begin with, I gave up every idea of returning to the passage that had brought us to that accursed chamber. I did not trouble about the possibility of working the inside stone that closed the passage; and this for the simple reason that to do so was out of the question. We had dropped from too great a height into the torture-chamber; there was no furniture to help us reach that passage; not even the branch of the iron tree, not even each other’s shoulders were of any avail.

There was only one possible outlet, that opening into the Louis-Philippe room in which Erik and Christine Daaé were. But, though this outlet looked like an ordinary door on Christine’s side, it was absolutely invisible to us. We must therefore try to open it without even knowing where it was.

When I was quite sure that there was no hope for us from Christine Daaé’s side, when I had heard the monster dragging the poor girl from the Louis-Philippe room lest she should interfere with our tortures , I resolved to set to work without delay.
