"Something has been accomplished, then, by this delay," he observed. Then, as if ashamed of this momentary display of irritation, he added in the genial tones more natural to him: "I don't blame you for your good opinion of this interesting, but by no means reliable, young man, Miss Butterworth. A woman's kind heart stands in the way of her proper judgment of criminals." "You will not find its instincts fail even if you do its judgment." His bow was as full of politeness as it was lacking in conviction. "I hope you won't let your instincts lead you into any unnecessary detective work," he quietly suggested. "That I cannot promise. If you arrest Howard Van Burnam for murder, I may be tempted to meddle with matters which don't concern me." An amused smile broke through his simulated seriousness. "Pray accept my congratulations, then, in advance, ma'am. My health has been such that I have long anticipated giving up my profession; but if I am to have such assistants as you in my work, I shall be inclined to remain in it some time longer." "When a man as busy as you stops to indulge in sarcasm, he is in more or less good spirits. Such a condition, I am told, only prevails with detectives when they have come to a positive conclusion concerning the case they are engaged upon." "I see you already understand the members of your future profession." "As much as is necessary at this juncture," I retorted. Then seeing him about to repeat his bow, I added sharply: "You need not trouble yourself to show me too much politeness. If I meddle in this matter at all it will not be as your coadjutor, but as your rival." "My rival?" "Yes, your rival; and rivals are never good friends until one of them is hopelessly defeated." "Miss Butterworth, I see myself already at your feet." And with this sally and a short chuckle which did more than anything he had said towards settling me in my half-formed determination to do as I had threatened, he opened the door and quietly disappeared. XVIII. THE LITTLE PINCUSHION. The verdict rendered by the Coroner's jury showed it to be a more discriminating set of men than I had calculated upon. It was murder inflicted by a hand unknown. I was so gratified by this that I left the court-room in quite an agitated frame of mind, so agitated, indeed, that I walked through one door instead of another, and thus came unexpectedly upon a group formed almost exclusively of the Van Burnam family. Starting back, for I dislike anything that looks like intrusion, especially when no great end is to be gained by it, I was about to retrace my steps when I felt two soft arms about my neck. "Oh, Miss Butterworth, isn't it a mercy that this dreadful thing is over! I don't know when I have ever felt anything so keenly." It was Isabella Van Burnam.
