If one should lose oneself therein, one might wander for days, as one did in catacombs.... Having no tallow candle, but only an electric torch, one might eat one's boots ... the very rats....

Not repressing a shudder, Henry stood hesitating at the cross-roads, looking this way and that, his ears strained to listen for sounds.

And presently, turning a corner, he perceived that there were sounds—footsteps and low voices, advancing down the left-hand passage towards him.
