"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.
"After Mannion was discharged as cured, he proceeded to make the next move in the game. I suppose you know, Mr. Feversham, that there are now many surgeons, professionals and quacks, who make a specialty of changing facial appearance. Twenty years ago the thing was almost unheard of. Now there have been so many demonstrations that the practise is carried on to an extent that would amaze you were you to be furnished with the statistics. There is one of these practitioners in Baltimore. I sent Chick to investigate. He proved the correctness of my theory, and he brought back these."
The detective from his pocketbook took two small photographs and handed them to Feversham. One was a counterfeit full-length presentment of Arthur Mannion as he appeared before the disguise, but after the amputation, and, facially, as Nick had seen him at the house on L Street; the other was a reproduction of the person of the so-called Peter Mannion.
"'Before taking,' and 'After taking,'" said Nick, with a smile. "Do you understand? And do you notice that each picture is of a one-armed man?"
"Yes. One was taken when the patient arrived; the other when the operation had been performed. If I used slang I should say it is a dead give-away." said Feversham.
"It is nothing else. Surgery fixed the features and changed the workings of the vocal chords, while chlorine or peroxide of hydrogen altered the color of the hair and eyebrows. Besides all this, I have other evidence of a minor nature which goes to cement the case against Arthur Mannion."
"What you have offered is sufficient, Mr. Carter. It is evidence overwhelming in its nature. Confront your prisoner with it and he must confess."
