The liveliest imagination could never have discovered in these heavy-faced, slow-spoken, and comfortably muffled farmers two lynx-eyed emissaries of the law, on the track of a felon. Their disguise was admirable. When more passengers crowded in, the two farmers grunted out agricultural jokes to each other, or read the county paper, or apprised the intrinsic value of each snow-capped barn, and white-ridged field, and huge wheat-stack they passed with a zest and eagerness positively infectious, until every one inside was drawn into the argument, and a few shrewd questions had been asked and innocently answered, which disclosed the fact that a man in a fur coat had galloped up the road three-quarters of an hour ago upon a gray horse. "Thought Caerlyon's mare was missing when I went to his stables," muttered one detective to the other; "he has got off before we left the town. All right; we'll catch up." But they did not catch up that night; and although the two officers slept in a room across the passage from Miss Walsingham's, in the hotel at Cirencester, they saw no one attempt either to communicate with her or to molest her. So it remained all during the next day's cold and weary journey, the masked detectives carefully kept close by the threatened young lady, and furtively watched each passenger who entered or left the car; but the ruffian was not to be traced, his menace to Margaret was but an empty vaunt; her precautions seemed to have effectually routed him. At seven o'clock that Thursday evening the train glided into the Regis station-house, the red lights glimmered on the platform, the crowd jostled, surged, and receded; and when the way seemed clear, one of the detectives got out to fetch a cab for Margaret before she should leave the car. While he was gone a close carriage rolled into the shed, and the driver, touching his hat to Margaret, whom he could see at the car window, offered his services and his cab. "This will do," said she to Purcell. "When Adams brings the other cab, our friends will need it to go to their hotel. Time is passing, and I must keep my engagement with Mr. Emersham." The remaining detective got out and stood a yard or so in advance of the cab-driver, who was opening his coach-door; and Purcell assisted his mistress out of the car to the platform, and then turned round and stooped to pick up her traveling-bag from the planks where he had thrown it. In a moment the long-expected crisis came, so long delayed, so startling now when they thought it was too late to fear it longer. A man darted out of the shadow of the station-house, and sprang like a panther on his victim. He threw the stooping Purcell violently upon the ground, seized Margaret, and hurried her with a giant's strength to the door of the cab, into which he tried to force her. "Get in with you, or I'll blow your brains out!" hissed his desperate voice in her ear.
