According to contemporary reviews:
The story as told in the drama ran closely alongside the familiar narrative in the book until the escape of Rufus Dawes disguised in the garments of the repentant Mr. North. In the drama the escape is prevented by Maurice Frere. That scoundrel's efforts however are foiled at the last moment by the arrival of a free pardon for Dawes. This was brought about by the confession of John Rex. The play ends with the death of Maurice Frere at the hands of Gabbett, and the departure of Rufus Dawes and Sylvia for England.
