Just before nine o'clock he returned with Dobson and Leon. They made a very complete reconnaissance of the Tower, and for a moment Heritage thought that they were about to try to force an entrance. They tugged and hammered at the great oak door, which he had further strengthened by erecting behind it a pile of the heaviest lumber he could find in the place. It was imperative that they should not get in, and he got Dickson's pistol ready with the firm intention of shooting them if necessary. But they did nothing, except to hold a conference in the hazel clump a hundred yards to the north, when Dobson seemed to be laying down the law, and Leon spoke rapidly with a great fluttering of hands. They were obviously puzzled by the sight of Heritage, whom they believed to have left the neighbourhood. Then Dobson went off, leaving Leon and Spidel on guard, one at the edge of the shrubberies between the Tower and the House, the other on the side nearest the Laver glen. These were their posts, but they did sentry-go around the building, and passed so close to Heritage's window that he could have tossed a cigarette on their heads. It occurred to him that he ought to get busy with camouflage. They must be convinced that the Princess was in the place, for he wanted their whole mind to be devoted to the siege. He rummaged among the ladies' baggage, and extracted a skirt and a coloured scarf. The latter he managed to flutter so that it could be seen at the window the next time one of the watchers came within sight. He also fixed up the skirt so that the fringe of it could be seen, and, when Leon appeared below, he was in the shadow talking rapid French in a very fair imitation of the tones of Cousin Eugenie. The ruse had its effect, for Leon promptly went off to tell Spidel, and when Dobson appeared he too was given the news. This seemed to settle their plans, for all three remained on guard, Dobson nearest to the Tower, seated on an outcrop of rock with his mackintosh collar turned up, and his eyes usually turned to the misty sea.
