"It was," answered Stewart, "yet the chief must have been overpersuaded. Look here!" and the colonel held forth a scrap of paper. Amy Lawrence, hearing something like the gasp of a sufferer in sudden pain, turned quickly and saw that every vestige of color had left Mrs. Garrison's face--that she was almost reeling on the step. Before she could call attention to it, Armstrong, who had taken and glanced curiously at the scrap, whirled suddenly, and his eyes, in stern menace, swept the spot where the little lady clung but an instant before. As suddenly Mrs. Garrison had sprung from the step and vanished. CHAPTER VII. Billy Gray was indeed in close arrest and the grim prophecy was fulfilled--Colonel Canker was proving "anything but a guardian angel to him." The whole regiment, officers and men, barring only the commander, was practically in mourning with sorrow for him and chagrin over its own discomfiture. Not only one important prisoner was gone, but two; not only two, but four. No man in authority was able to say just when or how it happened, for it was Canker's own order that the prisoners should not be paraded when the guard fell in at night. They were there at tattoo and at taps "all secure." The officer of the guard, said several soldiers, had quite a long talk with one of the prisoners--young Morton--just after tattoo, at which time the entire guard had been inspected by the commanding officer himself. But at reveille four most important prisoners were gone and, such was Canker's wrath, not only was Gray in arrest, but the sergeant of the guard also, while the three luckless men who were successively posted as sentries during the night at the back of the wooden shell that served as a guardhouse--were now in close confinement in the place of the escaped quartette.
