ON our way back I received from the runner some explanation of his apparently unaccountable proceedings in reference to myself. To begin at the beginning, it turned out that the first act of the officers, on their release from the workroom in the red-brick house, was to institute a careful search for papers in the doctor’s study and bedroom. Among the other documents that he had not had time to destroy, was a letter to him from Alicia, which they took from one of the pockets of his dressing-gown. Finding, from the report of the men who had followed the gig, that he had distanced all pursuit, and having therefore no direct clew to his whereabout, they had been obliged to hunt after him in various directions, on pure speculation. Alicia’s letter to her father gave the address of the house at Crickgelly; and to this the runner repaired, on the chance of intercepting or discovering any communications which the doctor might make to his daughter, Screw being taken with the officer to identify the young lady. After leaving the last coach, they posted to within a mile of Crickgelly, and then walked into the village, in order to excite no special attention, should the doctor be lurking in the neighborhood. The runner had tried ineffectually to gain admission as a visitor at Zion Place. After having the door shut on him, he and Screw had watched the house and village, and had seen me approach Number Two. Their suspicions were directly excited. Thus far, Screw had not recognized, nor even observed me; but he immediately identified me by my voice, while I was parleying with the stupid servant at the door. The runner, hearing who I was, reasonably enough concluded that I must be the recognized medium of communication between the doctor and his daughter, especially when he found that I was admitted, instantly after calling, past the servant, to some one inside the house. Leaving Screw on the watch, he went to the inn, discovered himself privately to the landlord, and made sure (in more ways than one, as I conjectured) of knowing when, and in what direction, I should leave Crickgelly. On finding that I was to leave it the next morning, with Alicia and Mrs. Baggs, he immediately suspected that I was charged with the duty of taking the daughter to, or near, the place chosen for the father’s retreat; and had therefore abstained from interfering prematurely with my movements. Knowing whither we were bound in the cart, he had ridden after us, well out of sight, with his countryman’s disguise ready for use in the saddle-bags--Screw, in case of any mistakes or mystifications, being left behind on the watch at Crickgelly.
