Dick Prescott drew further back into the shadow, noiselessly, and kept his eye on the distant glow until he heard the yearling returning.
"Sentry!" called Prescott sharply. The yearling, his piece at port arms, came on the run.
"Investigate that glow yonder," ordered Prescott.
"Very good, sir!"
Prescott and the sentry started together. For an instant the glow wavered, as though the man that was behind the glow meditated taking to his heels.
"Halt!" called the sentry. "Who's there?"
Now the glow disappeared, but cadet captain and sentry were close enough to see the outlines of a figure in cadet uniform.
The figure still moved uncertainly, as though bent on flight.
But the sight of two pursuers seemed to change the unknown's mind.
"A cadet," he called, in answer to the sentry's challenge.
The sentry halted.
