"A mere trifle, that!" he declared. "I can assure you that I could have taken it out of your pocket, if I had desired, without your feeling a thing." "Wonderful!" I murmured, feeling distinctly uncomfortable. "Just a gift!" he continued modestly. "We all have our talents, you know. I have ordered some special coffee." I was beginning to think rapidly now. "By the by," I asked, "what is Mr. Cullen's profession?" "He is a detective," Mr. Parker answered, without hesitation; "and, to my mind, a singularly bad one. For two months he has had what they call his eye on me. Between ourselves I think he will have his eye on me still in another two months' time. I am sure I hope so, for I frankly admit that half the savor of life would be gone if my friend, Mr. Cullen, were to finally give me up as a bad job and leave me alone." I suppose that something of what I was feeling was reflected in my face. I had always considered myself a man of the world and I was interested enough in my fellows to enjoy mixing with all classes. But there was the girl! "You are thinking--!" my companion began softly. "Your friend," I interrupted, "has just entered the restaurant. He is coming toward this table." Mr. Parker's expression never changed. Not a muscle twitched. His tone was even careless. "Just as well, perhaps," he remarked, "that we worked that little conjuring trick." The detective stood once more at our table. My instinctive dislike of him was now an accomplished thing. I hated his smile of subdued triumph, and all my fundamental ideas as to law and order were seriously affected by it. I was distinctly on the side of my new acquaintance. "I am sorry to interrupt this little feast," Mr. Cullen said, "but I shall have to trouble you both to come with me for a short time." Mr. Parker carefully clipped the end of his cigar and leaned back in his chair while he lit it. "My friend Cullen," he remonstrated, "I have no objection to offering myself up as a victim to your super-abundant energy and trotting about with you wherever you choose; but when it comes to dragging my friends into it, I just want to say right here that I think you are carrying things a little too far--just a little too far, sir." "If either of you seriously object to my request," Mr. Cullen replied doggedly, "I can put the matter on a different basis." "Who is this friend of yours and why should we go anywhere with him?" I asked. Mr. Parker shook his head mournfully. "You may well ask," he sighed. "You may not think it, to look at his ingenuous and honest expression, but the fact, nevertheless, remains that Mr. Cullen is a misguided but zealous member of the Sherlock Holmes fraternity: in short, a detective." I rose to my feet with some alacrity. "Anything in the shape of an adventure--" I began.
