"We failed to take him," said Rosmore. "There was no choice left but to let him go, and I admit I was disappointed as I rode through the village, close to an inn we had searched, on my way to beg a night's entertainment from my friend, Sir Philip Faulkner. There was some kind of feast in the village, and in a barn by the roadside there was dancing going on to the scraping of a fiddle. I have no soul for music, but the notes of that fiddle haunted my sleep that night and all the next day as I rode back to Lenfield. At Lenfield I understood why. That little sequence of notes was familiar to me. You must often have heard it yourself. I was convinced that the fiddler was none other than Martin Fairley." "Martin!" exclaimed Barbara. "Surely he would not be so far afield?" "I asked myself the same question," said Rosmore, "and I acted promptly as well. I have often warned Sir John that there was method in Martin's madness, and in this case, at any rate, I was right. Yesterday Martin travelled back towards Aylingford in company with a stranger. Unless I am in error, that stranger was Gilbert Crosby, otherwise known as Galloping Hermit, and I have taken care to guard every road of escape from the Abbey to-night." "Certainly a wise precaution," said Barbara quietly; "but how does it concern me?" "Can you swear that you did not send Martin to bring this fellow to Aylingford?" said Sir John. "You certainly had some interest in this man Crosby, and Martin would try and do your bidding if you asked him to fetch you the moon." "My interest was surely natural," Barbara answered, "for I assure you I was in an unpleasant situation at Newgate when this man came to my rescue--Lord Rosmore has doubtless told you the circumstances--but I certainly did not send Martin to bring this man to Aylingford." She laughed lightly as though the mere suggestion were absurd. So far she could answer honestly, but she dreaded the next question. "I do not suppose my niece would do such a thing," returned Sir John, "but the world is hardly likely to have the same faith in her. I warrant even you have your doubts, Lord Rosmore." "I assure you, Mistress Barbara, your uncle has no reason to suggest such a thing," said Rosmore. "As I have said, I am told off for unpleasant duty, and that duty has brought me to Aylingford to arrest a rebel, and compels me also to arrest Martin for assisting a rebel." "Poor Martin! A madman!" said Barbara. "I have much doubt as to his madness," was the answer, "but you have only to persist, and those doubts shall vanish. If you desire it, Martin shall escape--you have my word for that." Barbara was alert. She was prepared to have traps set for her, and had no intention of stepping into them if she could help it. "That is generous of you, Lord Rosmore," she said, thanking him with a curtsy, "but I would not ask you to neglect your duty."
