Jack could no longer resist the gift. He kissed her brow and thanked her again and again, and promised never to forget her. He felt honestly what he said. Jack slept very little all that night, thinking of what he was to see in London, and the adventures he might meet with on his journey there. Whatever suspicions might have arisen in his mind he shut out, anxious to have nothing to interfere with the pleasure he anticipated. The light of Pearson's lamp, as it gleamed in his eyes when he came to call him in the morning, aroused him from his sleep, and he found the horses already at the door prepared for starting. The dame and Elizabeth were on foot with breakfast prepared, and they gave him a friendly farewell, as, following Long Sam's example, he stepped out to mount his horse. A thick rime covered the ground, and a cold air blew across the fens, as the two riders with their charges took their way south. Jack, who by this time was well accustomed to the devious track across the fens, led the way at as rapid a pace as the horses could move, closely followed by Long Sam, who was now dressed as an ordinary jockey or rough-rider. They stopped to bait at various places: sometimes at the private residence of some gentleman who Long Sam said wished to look at their horses; at other times at a farm-house, and occasionally at inns, but these were generally avoided. While traversing an open country, Long Sam called Jack by his side. "You will understand, Deane," he observed, "that you have a very simple part to play when you reach London; but I must have your promise that you will do nothing without my orders, and that you will make all the inquiries I may direct, and gain all the information you can on certain points which I will explain to you. You will thus be enabled to render great service to an important cause, and run no risk or danger yourself." "As to that," answered Jack, "I am ready enough to run all sorts of risks where there is a good object to be attained; and I would rather be trusted than asked to act in the dark, as I am now doing!" Long Sam smiled grimly. "Others may not be so willing to trust you as you suppose," he answered. "Indeed, it is better for all parties that you should not be acquainted with what is taking place. I wish you, however, to understand, that the men with whom I am engaged are persons of honour and character, and are not likely to do any act unworthy of their position." "Then there _is_ some plot or scheme afoot?" said Jack. "I have long thought so, but could gain no information about the matter." "You are right in that respect," answered Long Sam: "there is an important scheme about to be carried out; and as soon as you have given proof of your fitness to engage in it, you shall be informed as to the particulars. In the meantime, all I require is simple obedience to my directions, and then all will be well."
