Kennedy was itching to get at them and prevent them, but he saw that, by knowledge gained, he would be in a position to act more effectively than if he suddenly alarmed them. Therefore the pair stood by until they had finished their hideous work of filling each chum with the most deadly and infectious malady known to medical science. Presently, when they had finished, the old driver, still insensible, was lifted from his seat, carried into the wood, and there left, while one of the conspirators--who they could now see was dressed as a farm-hand, and would no doubt pose as a new labourer from Furze Down--took his place and drove on as though nothing had happened, leaving the other two to make their way back to the car. When the red rear-light of the waggon was receding, Kennedy and Ella followed it, for it did not proceed at much more than walking pace. They walked along in silence till they saw the two men re-enter the car, leaving their companion to deliver the milk at the camp. Evidently a fourth man had been waiting in the car for, as soon as they were in, the man who drove turned the car, which went back in the direction it had come, evidently intending to meet the second waggon, which was due to come up an hour afterwards. No doubt the same programme would be repeated, and the fourth man would drive the second car to the adjacent camp. As soon, however, as the car had got clear away, Kennedy and his well-beloved ran to their motorcycles, mounted them, and in a short time had passed in front of the milk-waggon ere it could get down into Shipborne village. Putting their motors against a fence, they waited until the waggon came up, when Kennedy stepped into the road, and flashing an electric lamp on to the driver's face, at the same time fired a revolver point-blank at him. This gave the fellow such a sudden and unexpected scare that he leaped down from the waggon and, next moment, had disappeared into the darkness, while Ella rushed to the horses' heads and stopped them. "That's all right!" laughed Kennedy. "Have you got your thick gloves on?" "Yes, dear." "Well, be careful that not a drop of milk goes over your hands or feet. There's lots of time to pitch it all out on the roadway." Then climbing into the waggon the pair, by a pre-arranged plan, began to open the chums and turn their contents out of the waggon until the whole wet roadway was white with milk, which soaked into the ground and ran into the gutters and down the drains: for, fortunately, being near Shipborne, the footpaths on either side were drained, and by that any chance of infection later would, they knew, be minimised. Each chum they turned upon its side until not a drain of milk remained within, and then, leading the horses to graze on the grass at the roadside, the pair sped swiftly back along the road in the direction the car had taken.
