On account of his extravagance and dissipation, Col. Ryder disowns his son and casts him off. Guy, resolved to redeem himself, joins an Indian regiment as a private, and leaves England. Ryder dies five years later and leaves Alice, his daughter, to the guardianship of his old comrade, Col. Lawrence. Lawrence is ordered out to India and takes Alice with him. He is in command of the regiment in which Guy is now a lieutenant, under the name of Denton. Guy knows his sister, because he has heard of his father's death and will, but she does not recognize him. Major Jervis lays siege to Alice. She is young and easily flattered. Guy sees what is going on, but is at a loss to know what to do. He overhears Jervis persuade her to come to his quarters. That night he goes there too, and finds Alice waiting for Jervis, who has unexpectedly been called out. She is at first angry with his interference, but he reveals to her who he is and she sees her folly. Jervis returns and tries to keep Alice, but Guy makes her go. He quarrels with Jervis, who tries to draw a pistol on him. They struggle. The pistol goes off and Jervis is slightly wounded. He accuses Guy of having attacked him, and Guy refuses to speak in his own defense, for fear of compromising Alice. Alice hears what has happened and confesses her folly to Col. Lawrence, who goes to Jervis, forces him to resign and to write an exoneration of Guy. Guy is honorably discharged by the court martial on this evidence and restored to the arms of the sister whose honor he protected.
