Jackson Feversham, who had been kept in the dark regarding the identity of the one-armed man, could not believe that the murderer of Playfair was the soldierly person who had represented himself to be the murderer's uncle. "Why, he's one-armed, there's no sham there, his hair is light, his features are different, and he speaks in a different voice. I remember Arthur Mannion well, and this man bears no resemblance to him." "All the same," said Nick stoutly, "I can prove that he is Arthur Mannion, and before twenty-four hours he will confess that he is!" Playfair's friend and executor was now in Nick's rooms. The other persons present were Chick and Patsy. The detective spoke with such conviction that Feversham was impressed. "How did you get at the secret?" he asked. "By work, by using the powers which nature gave me and which experience has sharpened, and by the invaluable assistance of Chick and Patsy. I suspected the uncle when I heard of his visit to the hospital, my suspicions were deepened when I first met the man at Craven's house. He had but one arm, that is true, but it struck me as a singular circumstance that the missing member should be the left one, the arm to which, upon Arthur Mannion, when I had last seen him, was attached a hand with half a finger missing. An accident would account for the amputation, and if an accident to Mannion had occurred within a radius of one or even two hundred miles, the fact could be easily ascertained, both through telegraphic and private inquiry. I tried the private way first, and within a week Chick lit upon the surgeon who amputated Arthur Mannion's arm. While on his way, traveling mainly by night, from Alexandria to Baltimore, Mannion fell under a freight-train. He was stealing a ride with some hoboes, and, being awkward at brake-beam work, slipped and fell. The accident happened near a station--I had looked for the very thing--and a railway surgeon removed the arm and had the patient, who gave an assumed name, removed to St. Luke's Hospital, Baltimore. In the hospital Mannion met Knocker Jilson, a tramp he had struck up an acquaintance with while both were on the road. Do you begin to see, Mr. Feversham?" "Yes, light is breaking fast. You are a very shrewd man, Mr. Carter. Hereafter I shall take whatever you say as the law and gospel." "Before leaving the hospital Mannion arranged his deal with Jilson. The fellow was booked for an early death, and as he grew weaker he thought of his mother, whom for years he had shamefully neglected. Mannion saw his chance. He offered to send Mrs. Jilson money, and to provide for the few years she has yet to live, if Jilson, on his part, would consent to a harmless deception. Jilson listened and consented. He would have done more, if it had been necessary, than was asked of him, for the promise to relieve his mother's necessities was an inducement that would have made him swallow any kind of bait.
