Guided by Officer Lloyd, the little band dashed on, arriving at Bryantown on Tuesday. Here they arrested John Lloyd, of the hotel at Surrattsville, of whom they had previously inquired for the murderers, and he had said positively that he neither knew them nor had seen anybody whatever on the night of the crime. He was returning in a wagon, with his wife, whom he had ordered, the day before, to go on a visit to Allen's Fresh, The Monday afterward he started to bring her back. This woman, frightened at the arrest, acknowledged at once that in her husband's conduct there was some inexplicable mystery. He was taciturn and defiant as before, until confronted by some of his old Union neighbors. The few Unionists of Prince George's and Charles counties, long persecuted and intimidated, now came forward and gave important testimony. Among these was one Roby, a very fat and very zealous old gentleman, whose professions were as ample as his perspiration. He told the officers of the secret meetings for conspiracy's, sake at Lloyd's Hotel, and although a very John Gilpin on horseback, rode here and there to his great loss of wind and repose, fastening fire-coals upon the guilty or suspected. Lloyd was turned over to Mr. Cottingham, who had established a jail at Robytown; that night his house was searched, and Booth's carbine found hidden in the wall. Three days afterward, Lloyd himself confessed--and his neck is quite nervous at this writing. This little party, under the untiring Lovett, examined all the farm-houses below Washington resorting to many shrewd expedients, and taking note of the great swamps to the east of Port Tobacco; they reached Newport at last and fastened tacit guilt upon many residents. Beyond Bryantown they overhauled the residence of Doctor Mudd and found Booth's boot. This was before Lloyd confessed, and was the first positive trace the officers had that they were really close upon the assassins. I do not recall anything more wild and startling than this vague and dangerous exploration of a dimly known, hostile, and ignorant country. To these few detectives we owe much of the subsequent successful prosecution of the pursuit. They were the Hebrew spies.
