LIST OF ILLUSTRATIONS A FOUL BLOW . . . . . . _Frontispiece_ (_see page_ 52) "HANDS UP!" A LONG WAY BACK THE INTRUDER IN KHAKI CHAPTER I A CHANCE MEETING Mr. Kishimaru smiled, and rubbed his long lean hands gently the one over the other. "Yes, Mr. Amory, you make great progress," he said, in low smooth tones, and with the careful enunciation of one speaking a foreign tongue. "You will be an artist. Yes, I assure you: jujutsu is a fine art; more than that, it is an application of pure science. I say that, and I know. Compare it with boxing, that which your grandfathers called the noble art. Rapidity of movement, yes; quickness of eye and judgment, yes; but delicacy of touch--ah! jujutsu has it, boxing no. There is nothing brutal about jujutsu." Kenneth Amory smiled back at the enthusiastic little Japanese, and rubbed his left shoulder. "Nothing brutal, I agree," he said. "But it has been a dry summer, Mr. Kishimaru." "A dry summer?" the Japanese repeated, still smiling, but with an air of puzzlement. "Yes; the turf’s uncommonly hard, and I came down a pretty good whack that last time." "I am sorry. You have not quite recovered your strength yet, or you would not have fallen so heavily. But you do well; it is good exercise, for body and mind too. A little rest, and we will try another throw." Kenneth Amory was seated on a bench on the lawn where, in summer, Mr. Kishimaru instructed his pupils in the fine art of jujutsu. He wore a loose white belted tunic and shorts: head and legs were bare. Mr. Kishimaru, a wiry little Japanese of about thirty-five, similarly clad, walked up and down, expounding the principles of his art. A bell rang in the house. The garden door opened, and a tall young fellow of some twenty years came with quick step on to the lawn. "Hullo, Kishimaru!" he cried. "How do? Have you got a minute?" He glanced towards the figure on the bench, but did not wait for an answer. "Just back from Canada--to enlist. Got to smash the Germans, you know. But look here; just spare a minute to show me the Koshinage, will you? I was in a lumber camp, you know, out west; lumbering’s hard work; no cricket or anything else; had to do something; taught ’em jujutsu, odd times, you know. But the Koshinage--I fairly came to grief over that: tried it on a big chap, and came a regular cropper. Made me look pretty small; I’d been explaining that I’d throw any fellow, no matter how big. Somehow it didn’t come off: must have forgotten something, I suppose. I’ve only got a few minutes; have to catch the 4.30 at St. Pancras; just put me through it once or twice, there’s a good chap." Mr. Kishimaru rubbed his hands all through this impetuous address. He was always pleased to see an old pupil, and Harry Randall, voluble, always in a hurry, had been one of his best pupils a year or two before.
