Meanwhile, as Flint left Brent Rock, his fear of the Automaton returned to him with redoubled force. He had been false to his mission. Nor had he even succeeded in his treachery. A few minutes he had been certain that Eva would come to Baker's dock at the time set, but now doubts began to assail him. With her obvious faith in Locke, she might decide on the chemist's antidote, and there was always a possibility that it might restore Brent, in which case Flint realized that his life would be forfeit to the Automaton.
Nor were his fears unfounded. He had barely passed the fountain where, half an hour before, he had been set free, when an emissary came out from behind a neighboring tree and took up his trail.
