It was not enough to reach the walls; an opening in them must be accomplished, and to attain this purpose the party only had their pocket-knives. Happily the temple walls were built of brick and wood, which could be penetrated with little difficulty; after one brick had been taken out, the rest would yield easily. They set noiselessly to work, and the Parsee on one side and Passepartout on the other began to loosen the bricks so as to make an aperture two feet wide. They were getting on rapidly, when suddenly a cry was heard in the interior of the temple, followed almost instantly by other cries replying from the outside. Passepartout and the guide stopped. Had they been heard? Was the alarm being given? Common prudence urged them to retire, and they did so, followed by Phileas Fogg and Sir Francis. They again hid themselves in the wood, and waited till the disturbance, whatever it might be, ceased, holding themselves ready to resume their attempt without delay. But, awkwardly enough, the guards now appeared at the rear of the temple, and there installed themselves, in readiness to prevent a surprise. It would be difficult to describe the disappointment of the party, thus interrupted in their work. They could not now reach the victim; how, then, could they save her? Sir Francis shook his fists, Passepartout was beside himself, and the guide gnashed his teeth with rage. The tranquil Fogg waited, without betraying any emotion. "We have nothing to do but to go away," whispered Sir Francis. "Nothing but to go away," echoed the guide. "Stop," said Fogg. "I am only due at Allahabad tomorrow before noon." "But what can you hope to do?" asked Sir Francis. "In a few hours it will be daylight, and--" "The chance which now seems lost may present itself at the last moment." Sir Francis would have liked to read Phileas Fogg's eyes. What was this cool Englishman thinking of? Was he planning to make a rush for the young woman at the very moment of the sacrifice, and boldly snatch her from her executioners? This would be utter folly, and it was hard to admit that Fogg was such a fool. Sir Francis consented, however, to remain to the end of this terrible drama. The guide led them to the rear of the glade, where they were able to observe the sleeping groups. Meanwhile Passepartout, who had perched himself on the lower branches of a tree, was resolving an idea which had at first struck him like a flash, and which was now firmly lodged in his brain. He had commenced by saying to himself, "What folly!" and then he repeated, "Why not, after all? It's a chance--perhaps the only one; and with such sots!" Thinking thus, he slipped, with the suppleness of a serpent, to the lowest branches, the ends of which bent almost to the ground.
