A thick fog envelops London, masking tragedy. Irene waits to run away with Bosinney, who is driven to distraction when hearing the news of Irene's rape. The next day, the Forsyte men gather en masse to support Soames, as the case of Forsyte vs. Bosinney is heard in court. The defendant is nowhere to be found, and he loses the case. June begs Old Jo to save Bosinney by purchasing the house at Robin Hill, now finished but empty. Brothers Old Jo and James, and their sons Young Jo and Soames, gather at the morgue to identify a man who was run down by a carriage in the fog; it is Bosinney. (thetvdb.com)
