Suddenly in a glass he caught his own reflection--his hair dishevelled, his collar bent, and felt an insane desire, despite these minor flaws, to shake himself by the hand, as though, by personal effort, he had prolonged his days! The doctor still stood motionless, gazing into space. In the silence of the room a faint pattering told of the almond blossom falling on the polished floor. McTaggart straightened his tie, and with his back turned, surreptitiously began to dive in his pocket for the fee. He found it at last, and took a step forward toward the absorbed figure at the desk. "I'd like to know," he suggested, "what you really think is the cause...." "Of course!" The lean face lifted with a start. "You must forgive me. The fact is"--he smiled--"I'm too interested in your case to remember your natural anxiety. I think your present trouble is caused by an error in digestion. The palpitation comes from that and the other symptoms too. A little care with your diet--I'll write you a prescription--a bismuth mixture to be taken after meals. But if you've further worry, come to me again. As a friend--you understand? ... Oh, no!--it's pure selfishness. I don't want to lose sight of you. You see--to cut it short--you're by way of being a freak! You've got--for want of a better name--what I call a Double Heart. One heart's on your right side and one's in the proper place. It's the most amazing thing I've ever come across. You're perfectly healthy--sound as a bell. I shouldn't wonder, upon my soul, if you hadn't two lives!" McTaggart stared at him, trying to take it in. "It sounds rather mad. But you say it doesn't matter?" "It doesn't seem to affect your circulation in the least. I'm certain what you complain about is due to indigestion--the aftermath perhaps of a touch of Influenza." A twinkle crept into the blue eyes watching him. "I suppose one heart's Italian and the other purely Scotch?" He ventured the joke against himself in a spirit of relief. "That's it!" His new friend laughed ... "a dual personality. Dr. Jekyll and Mr. Hyde, with a physical excuse." He gave loose reins for a moment to his vivid imagination, which swept him on with the current of his thoughts. "You're not married, you say? Well--you'd better be careful. It might lead to bigamy! If so, refer to me." A curious expression came into the young man's face as he echoed the other's laugh with a trace of confusion. "A fair wife and a dark one? Porridge and ... Chianti!" He paid his fee and went out into the London fog. CHAPTER II McTaggart walked down Harley Street, his blue eyes full of light, still hugging the consciousness of a new lease of life.
