"No. 7," said Jimmy crisply. "That's what I'm after. No. 7." "And you think you'll find him in this house?" "I thought I might find a clue." "And you didn't?" "Not last night--no." "But this morning," said Loraine, breaking in suddenly. "Jimmy, you did find something this morning. I can see it by your face." "Well, I don't know if it is anything. But during the course of my stroll--" "Which stroll didn't take you far from the house, I imagine." "Strangely enough, it didn't. Round trip in the interior, we might call it. Well, as I say, I don't know whether there's anything in it or not. But I found this." With the celerity of a conjuror he produced a small bottle and tossed it over to the girls. It was half full of a white powder. "What do you think it is?" asked Bundle. "A white crystalline powder, that's what it is," said Jimmy. "And to any reader of detective fiction those words are both familiar and suggestive. Of course, if it turns out to be a new kind of patent tooth-powder, I shall be chagrined and annoyed." "Where did you find it?" asked Bundle sharply. "Ah!" said Jimmy, "that's my secret." And from that point he would not budge in spite of cajolery and insult. "Here we are at the garage," he said. "Let's hope the high-mettled Hispano has not been subjected to any indignities." The gentleman at the garage presented a bill for five shillings and made a few vague remarks about loose nuts. Bundle paid him with a sweet smile. "It's nice to know we all get money for nothing sometimes," she murmured to Jimmy. The three stood together in the road, silent for the moment as they each pondered the situation. "I know," said Bundle suddenly. "Know what?" "Something I meant to ask you--and nearly forgot. Do you remember that glove that Superintendent Battle found--the half-burnt one?" "Yes." "Didn't you say that he tried it on your hand?" "Yes--it was a shade big. That fits in with the idea of its being a big, hefty man who wore it." "That's not at all what I'm bothering about. Never mind the size of it. George and Sir Oswald were both there too, weren't they?" "Yes." "He could have given it to either of them to fit on?" "Yes, of course--" "But he didn't. He chose you. Jimmy, don't you see what that means?" Mr. Thesiger stared at her. "I'm sorry, Bundle. Possibly the jolly old brain isn't functioning as well as usual, but I haven't the faintest idea what you're talking about." "Don't you see, Loraine?" Loraine looked at her curiously, but shook her head. "Does it mean anything in particular?" "Of course it does. Don't you see--Jimmy had his right hand in a sling." "By Jove, Bundle," said Jimmy slowly. "It was rather odd now I come to think of it; it's being a left hand glove, I mean. Battle never said anything."
