Her first care was to inspect the apartment; but it afforded few hopes either of escape or protection. It contained neither secret passage nor trapdoor, and unless where the door by which she had entered joined the main building, seemed to be circumscribed by the round exterior wall of the turret. The door had no inside bolt or bar. The single window opened upon an embattled space surmounting the turret, which gave Rebecca, at first sight, some hopes of escaping; but she soon found it had no communication with any other part of the battlements, being an isolated bartisan, or balcony, secured, as usual, by a parapet, with embrasures, at which a few archers might be stationed for defending the turret, and flanking with their shot the wall of the castle on that side.
