"The story as you see sounded plausible enough, and if it proved to be untrue, it would reflect great credit on Sir David's gift of imagination. Felix Shap, as was only to be expected, denied it from beginning to end; the whole thing, he declared, was an impudent falsehood, based on a semblance of truth. It was quite true that he had adopted and for years had cared for his sister's son, who was subsequently killed in Gallipoli; it was also true that Alfred Carysfort had years ago paid some attention to his sister Berta, but there never was any question of marriage between them, young Carysfort deeming himself far too grand and well-born to marry the daughter of an obscure East Indian trader. Berta had subsequently married a man of mixed blood who deserted her and went off somewhere to Argentina or Honduras--Shap did not know where; at any rate, he was never heard of again. "In proof of his version of the romantic story, Felix Shap actually had a copy of his sister's marriage certificate, as well as one or two letters written at different times to his sister Berta by her rascally husband. He had, indeed, plenty of proofs for his assertions; but when Mr. Stonebridge asked for confirmation of Sir David's story, the latter appeared either unprepared or unwilling to produce any, whereupon, Mr. Stonebridge, on behalf of his client, entered an action for the recovery of certain royalties due to him on the sales of the Shap Fuelettes, the amount to be presently agreed on after examination of the audited accounts. "Thus matters stood when on that Wednesday night in February last, Mr. Stonebridge was found gagged and unconscious, the victim of a murderous and inexplicable assault. "On the Monday following, Mr. Felix Shap, accompanied by his friend, Mr. Lloyd, called on Mr. Medburn at the office in High Street. They had read in the papers certain details which had filled Shap with apprehension; they had read that the safe in the morning-room in Mr. Stonebridge's house had been obviously ransacked, and that the analysis of the ashes in the grate had revealed the presence of a large quantity of burnt paper. "'My friend Mr. Shap would like you to put his mind at rest, Mr.--er--Medburn,' Mr. Lloyd said, in an anxious, agitated tone of voice, 'that the papers relating to his case, which he entrusted to Mr. Stonebridge, are safely locked up in a safe at this office.'
