Twenty years pass. Lady Mason lives at Orley Farm with her adult son, Lucius. Samuel Dockwrath, a tenant, is asked to leave by Lucius, who wants to try new intensive farming methods. Aggrieved, and knowing of the original case (John Kenneby, one of the codicil witnesses, had been an unsuccessful suitor of his wife Miriam Usbech), Dockwrath investigates and finds a second deed signed by the same witnesses on the same date, though they can remember signing only one. He travels to Groby Park in Yorkshire, where Joseph Mason the younger lives with his comically parsimonious wife, and persuades Mason to have Lady Mason prosecuted for perjury. The prosecution fails, but Lady Mason later confesses privately that she committed the forgery, and is prompted by conscience to give up the estate.
