When the train arrived at Mardon Jenny bundled herself into a governess-cart drawn by a fat and elderly pony, and driven by one of her brothers. She offered Natty a seat, but he refused, as he caught sight of Eustace coming out of the station. "But I'll call in and see you tomorrow or this evening," said Natty. Whereat Jenny, afraid of this barefaced wooing--it was really quite improper said her heart--ordered the young Arrow to drive on. Natty watched the elderly pony toiling up the hill, then turned to greet Jarman. "Here you are!" said Natty, shaking hands. "I've just come down to put up with you for a day or two. Can you fix me?" Jarman was not quite prepared to extend this hospitality. He had a better opinion of Natty than of his friends. All the same, the young man was in touch with the Captain, and, being weak, was under his influence. Consequently, Berry might be employing Natty as a spy; as the report of Fairy Fan--if she made any--could not be entirely satisfactory to the little skipper. Had he been on the spot he would have made an exhaustive examination as to the whereabouts of the man he desired to hang. Nevertheless, Jarman fancied that he could control the weak nature of Denham quite as easily as Berry had done, and since the young man had come down he saw no reason why he should not make use of him. He could trust to Mildred's cleverness to keep him away from the summerhouse. Therefore, if Natty came and went at his own sweet will, Berry would be quite convinced that Lancaster had left the neighbourhood. It was a bold game, but the situation was so desperate that only boldness would allay suspicion. "Of course, I can put you up," said Jarman. "Shall we drive?" "No, I guess not. Let us send on the baggage and walk across. I have something important to say." "Wondering what this could be, Jarman saw that Natty's trunk was put on a fly, and, after directing the man to take it to the Shanty, walked on with his unexpected guest. Eustace had long since posted a letter written by Frank, according to the instruction of the sealed epistle, and it had been sent to Tamaroo at the General Post-Office. The man (for Tamaroo was a man according to Fan's half-confession) was directed to call at the Shanty and see Mr. Lancaster. But, needless to say, it was Jarman's intention to interview the visitor in place of Frank. Thus, if it was a plot in any way--but that was unlikely, seeing that the sealed letter came from Frank's father--the young fellow would not run the risk of being arrested. "I suppose you know that my secretary has left me?" said Eustace, seeing that Natty did not seem inclined to begin the conversation. "How should I know that?" asked Denham, sharply, and looking oddly at Jarman. "You came down with Miss Arrow, and she knows. Consequently--"
