It suddenly occurred to Robert Cairn that Ferrara was making in the direction of Mr. Saunderson's house at Dulwich Common; the house in which Myra had had her mysterious illness, in which she had remained until it had become evident that her safety depended upon her never being left alone for one moment. "What can be his object?" muttered Cairn. He wondered if Ferrara, for some inscrutable reason, was about to call upon Mr. Saunderson. But when the cab ahead, having passed the park, continued on past the lane in which the house was situated, he began to search for some other solution to the problem of Ferrara's destination. Suddenly he saw that the cab ahead had stopped. The driver of his own cab without slackening speed, pursued his way. Cairn crouched down upon the floor, fearful of being observed. No house was visible to right nor left, merely open fields; and he knew that it would be impossible for him to delay in such a spot without attracting attention. Ferrara's cab passed: "Keep on till I tell you to stop!" cried Cairn. He dropped the speaking-tube, and, turning, looked out through the little window at the back. Ferrara had dismissed his cab; he saw him entering a gate and crossing a field on the right of the road. Cairn turned again and took up the tube. "Stop at the first house we come to!" he directed. "Hurry!" Presently a deserted-looking building was reached, a large straggling house which obviously had no tenant. Here the man pulled up and Cairn leapt out. As he did so, he heard Ferrara's cab driving back by the way it had come. "Here," he said, and gave the man half a sovereign, "wait for me." He started back along the road at a run. Even had he suspected that he was followed, Ferrara could not have seen him. But when Cairn came up level with the gate through which Ferrara had gone, he slowed down and crept cautiously forward. Ferrara, who by this time had reached the other side of the field, was in the act of entering a barn-like building which evidently at some time had formed a portion of a farm. As the distant figure, opening one of the big doors, disappeared within: "The place of which Myra has been dreaming!" muttered Cairn. Certainly, viewed from that point, it seemed to answer, externally, to the girl's description. The roof was of moss-grown red tiles, and Cairn could imagine how the moonlight would readily find access through the chinks which beyond doubt existed in the weather-worn structure. He had little doubt that this was the place dreamt of, or seen clairvoyantly, by Myra, that this was the place to which Ferrara had retreated in order to conduct his nefarious operations.
