"See here, young lady," broke in the irate officer. "Mrs. Vence is hiding. While the police are about she'll not show. I intend to collect my men at the rectory and then come along to have a talk with the coastguard yonder. There is a man there I want to examine. Now, when Mrs. Vence sees that the coast is clear she may venture out, as she won't take any notice of you. Keep your eyes open and blow the whistle if you see her. That's all I ask." "You ask a great deal, sergeant," said Claudia, drily. "And my father?" "He will remain at the rectory with my men. Will you do what I ask?" "Yes. But I warn you that I don't anticipate success," said Claudia, slipping the whistle into her pocket. "Neither do I. But I'm grasping at straws," growled the sergeant, who was very hot and very angry. He was turning away from the barn to go to the rectory and collect his men, when Edwin stopped him for a moment. "Have you any objection to my taking a flight, sergeant?" he asked. "I want to try my machine now it is repaired?" Edwin quite expected the man to object, but, to his surprise, the sergeant at once assented. "Seeing you going away on the aeroplane will make Mrs. Vence think that we have given up the hunt, and she will venture out to escape. Go, by all means, Mr. Craver. I'll come back to see you start." Purse hurried away, and Edwin made ready his machine. He only intended to take a short flight over the water and then return, as he merely wished to see if the repairs were all right. To provide against accidents he placed a coil of rope on the pilot's seat. It might be wanted, and it might not. All the same, it was just as well that it should be there. Shortly, and just when Purse returned from the rectory, Edwin was ready, and called two or three coastguards from their station to assist in the ascent. While they ran the aeroplane along the ground to give it the impetus to rise, Purse cast his eyes here, there, and everywhere, in the hope of seeing Mrs. Vence. Why he expected her to remain in the vicinity of her crime it is impossible to say. But he could not help thinking that she was lurking about close at hand. However, his attention was called from watching by the ascent of the great machine, which rose majestically into the air, swept round in a great circle, and then turned its nose seaward. Looking up and following its flight, Purse walked along towards the coastguard station, leaving Claudia seated in the shadow near the front of the barn. She was behind one of the double doors, and could not be seen from within.
