Overview:It's time for the men from the Concert Party to start the return journey to Britain. Everyone is supposed to have injections before setting off. The vaccine runs out before Lofty gets his jabs, so he has to stay behind when the others begin their journey. A new batch of vaccine turns up after the others have left, so Lofty is given his injections and, accompanied by the Char Wallah, he sets off to try to catch up with the main evacuation party.
