“The human foxhound,” murmured Poirot, as he leaned back in a comfortable chair, and closed his eyes. “By all means, my friend. Au revoir.” I strolled out of the front door. It was certainly hot. I turned up the path we had taken the day before. I had a mind to study the scene of the crime myself. I did not go directly to the spot, however, but turned aside into the bushes, so as to come out on the links some hundred yards or so further to the right. If Giraud were still on the spot, I wanted to observe his methods before he knew of my presence. But the shrubbery here was much denser, and I had quite a struggle to force my way through. When I emerged at last on the course, it was quite unexpectedly and with such vigour that I cannoned heavily into a young lady who had been standing with her back to the plantation. She not unnaturally gave a suppressed shriek, but I, too, uttered an exclamation of surprise. For it was my friend of the train, Cinderella! The surprise was mutual. “You,” we both exclaimed simultaneously. The young lady recovered herself first. “My only Aunt!” she exclaimed. “What are you doing here?” “For the matter of that, what are you?” I retorted. “When last I saw you, the day before yesterday, you were trotting home to England like a good little boy. Have they given you a season ticket to and fro, on the strength of your M.P.?” I ignored the end of the speech. “When last I saw you,” I said, “you were trotting home with your sister, like a good little girl. By the way, how is your sister?” A flash of white teeth rewarded me. “How kind of you to ask! My sister is well, I thank you.” “She is here with you?” “She remained in town,” said the minx with dignity. “I don’t believe you’ve got a sister,” I laughed. “If you have, her name is Harris!” “Do you remember mine?” she asked, with a smile. “Cinderella. But you’re going to tell me the real one now, aren’t you?” She shook her head with a wicked look. “Not even why you’re here?” “Oh, that! I suppose you’ve heard of members of my profession ‘resting.’” “At expensive French watering-places?” “Dirt cheap if you know where to go.” I eyed her keenly. “Still, you’d no intention of coming here when I met you two days ago?” “We all have our disappointments,” said Miss Cinderella sententiously. “There now, I’ve told you quite as much as is good for you. Little boys should not be inquisitive. You’ve not yet told me what you’re doing here? Got the M.P. in tow, I suppose, doing the gay boy on the beach.” I shook my head. “Guess again. You remember my telling you that my great friend was a detective?” “Yes?” “And perhaps you’ve heard about this crime—at the Villa Geneviève—?” She stared at me. Her breast heaved, and her eyes grew wide and round. “You don’t mean—that you’re in on _that?___”
