While such charitable conversation was passing at Emberton, the magistrates were not inactive; warrants, horses, and constables were dispatched in all directions, and both Dr. Wilton and Mr. Egerton, well knowing the blame that would attach to themselves, returned to the mansion to investigate by what means the prisoner had escaped. The constables in whose charge the prisoner had been left, and the room which he had occupied, were first examined. The two men declared upon oath, that no one had been admitted to the accused but themselves, since he had been remanded; that they had both slept in the ante-room; that the door had been locked all night; that the window was far too high to afford the means of evasion; and that they had both seen and spoken to Captain Delaware as late as eleven the preceding night. The inferior constable at the same time handed the fugitive's letter to Dr. Wilton, who opened and read it, while Mr. Egerton made the first superficial examination of the room; and, as his fellow-magistrate was about to institute a more rigorous investigation, the clergyman exclaimed-- "Stay, stay, Mr. Egerton, this letter concerns us both, and in it William Delaware alludes, in some measure, to the method of his intended escape. See here! He says the officers are entirely guiltless of it, as it is by a passage they are not acquainted with." "Then there must be some private entrance," said Mr. Egerton. "I dare say there is," answered Dr. Wilton; "but this letter, in many points, throws some new light upon the subject. Read it! Read it! and, at all events, let us, as far as we can, do the poor boy justice. Read it, my dear sir!" Mr. Egerton took it to the window, and read it attentively over. He then gave the letter back to Dr. Wilton, saying, "He makes out a good case against his accuser; but I am afraid, my dear doctor, that it will not screen himself. However, on every account--for charity's sake, and for the sake of mere justice--I will, of course, exert myself to the utmost--that is to say, quietly--quietly, you know, for the matter is nearly out of our hands--but I will exert myself to the utmost to discover every fact connected with the charge. In the mean time, we must do our duty, and endeavor to recover our prisoner: Let us examine the walls." "First examine the floor," said Dr. Wilton. "Sliding panels have not been to be found since the epoch of Udolpho, but trap-doors are to be met with in all these old houses."
