"I have arranged that he shall not interfere with you," said Quarles. "You will be able to go yachting to-morrow. I was obliged to fix matters so that I could come and go as I chose, and it was safer to draw the manager's attention to one man rather than allow him to suspect others, amongst them the very man we want to hoodwink, perhaps. The fact is, Wigan, I believe the gang know you are here, and think you are here on business. Plans will have been made accordingly, and it is therefore absolutely necessary that you should go on just as you have been doing. I don't think the hotel will be robbed now, but I am not sure. Sunshine or storm, go with Mrs. Selborne to-morrow. Exactly what is going to happen I do not know, but at the end of your cruise to-morrow you may want all your wits about you." "Are you staying in the hotel?" I asked. "No, at Hythe, and I spend some of my time on Romney Marsh. I am interested in a lonely house there. You must go; there is the gong. I must tell you about the house another time." "When shall I see you again?" "To-morrow night. Leave me here. I will sneak out after you have gone." It was natural my eyes should wander round the dining-room that night, trying to discover by intuition which was the man who might engineer a robbery at the hotel. Once the manager entered the room, and, knowing what I did, I could not doubt he wanted to satisfy himself that I was there. It did not worry me that Quarles had made use of me in this way; I was quite prepared to be arrested if the robbery did take place, but I was annoyed that the professor had told me so little. It was his way; I had had experience of it before, but it was treatment I had never been able to get used to. After dinner Mrs. Selborne joined me in the lounge for a little while, and talked about our sail next day, and then I was asked to make up a bridge table. Remembering Zena's attitude, according to Quarles, I was rather glad to get away from Mrs. Selborne. She played bridge, too, but not at my table. There was no burglary that night, and the following morning was as good for yachting as one could desire. However, we could not start at our usual time. The crew consisted of the skipper and two hands, and one of the hands came up to say that it was necessary to replace some gear, which would take until midday. Mrs. Selborne was very angry. "We shall have to kill time until twelve o 'clock," she said, turning to me. "It is a pity, but we'll get our sail somehow if all the gear goes wrong. It is very likely only an excuse to get a short day's work, but I am not expert enough to challenge my skipper." When we got aboard soon after noon, however, she had a great deal to say to the skipper; would have him point out exactly what had gone wrong, and showed him quite plainly she did not believe there need have been so long a delay; but she soon recovered her temper when she took the helm, and her good spirits became infectious.
