But the matter-of-fact tone and manner were on the surface. Boone secretly distrusted the few messages that came to his preceptor from the outside world. By such voices he might be called back again and hearken to the summons. Boone could not contemplate existence with both his idols ravished from his temple. Now he closed the door behind him in so preoccupied a mood that he left his rifle standing against the wall forgotten and McCalloway remained standing by the table rather inflexible of posture and sternly inquisitorial of countenance. "MacTavish," he said in sharply clipped syllables, "you are one of few--a very few--who know of my incognito and address. I have relied upon you implicitly to guard those secrets. I trust you can explain following me into what you must know was a retirement not to be trespassed upon without incurring my anger--my very serious anger." Respectfully, but with a face full of eager resoluteness, the other saluted again. "General," he said, "it's China--they need you there." "Sergeant"--an angry light leaped in the steel-gray eyes--"if they want me in China some one whom I have trusted has betrayed my identity. No living soul there ever heard of Victor McCalloway, _Mister_ McCalloway, not General Anything, mind you!" The newcomer crossed to the centre of the room, and his movements were quick and precise, as are those of the drill-ground. "To every other man on earth ye may be _Mister_ McCalloway--but to me ye are my general. Before I'd betray any trust ye might place in me, sor'r, I'd cut off that hand at the wrist, as ye ken, sor'r, full well. I've told nae soul where ye wor'r. I've only said that I'd seek for ye." "But in God's name how--?" "If I may interrupt ye, sor'r, I am no longer Sergeant Major MacTavish; I'm a time-retired man at home, but when I wear a uniform now it's that of the army of the Manchu Emperor. They seek to reorganize their army along western lines. They want genius. They ken nothin' of ye save that one Victor McCalloway was once a British officer of high rank who served so close to Dinwiddie, that Dinwiddie's strategy is known to him.--Read this, sor'r, and ye'll understand more of the matter." The General took the large, official-looking missive and stood for a moment with a drawn and concentrated brow before he slit its linen-lined covering. The feel of the thing in his fingers brought to him a certain stirring and quickening of the pulses: such a restiveness as may come to the retired thoroughbred at the far-off sound of the paddock bugle, or to the spent war horse at the rolling of drums.
