Knowing something has gone wrong which prevents them from returning to 2060 Oxford, the three time travelers attempt to determine an escape plan, but none of their efforts are successful. A fellow student, Gerald Phipps, who was supposed to be at Bletchley Park studying Ultra, never came through to his assignment. They realize that another Oxford historian, John Bartholomew, is also in their place and time, but understand this only less than a day before he will leave. (Bartholomew's time travel experience is the subject of Willis's short story "Fire Watch," written almost thirty years previously.) Frantically they try to get to him, but the three are separated and repeatedly delayed, not helped by the fact that this is the night of December 29, 1940, during which some of the worst raids of the war occurred. They are unable to find Bartholomew before he returns to 2054 Oxford. When Mike and Eileen figure out that Polly has a deadline in June 1943, and its implications, their search for a way out becomes even more desperate. Their frustration turns into tragedy when Mike is reported killed during a raid. Eileen refuses to accept his death, but upon realizing Alf and Binnie's mother has been dead for months, she volunteers to raise the orphans, thus giving her life, now trapped in the mid-20th century, a significant meaning. Polly fights with her about this, but Eileen is adamant and later proves to have become a very good mother to the children.
