Publisher's summary
Long ago, a massacre in a suburban house led to the young Harry Sullivan joining UNIT. But the murders were never solved. Years later, Harry and Naomi Cross investigate an oddity in the London Underground and uncover a whole different side to the capital.

Creatures of myth are running amok across the city in a conflict going back decades. And somewhere in the shadows lurks a new incarnation of their old friend...the Doctor. And he's here to stop a war.

Part one
Having felt useless at sea during the recent plague, Harry has an interview with Dr May for a job at a hospital and learns that the plague was cured by a man from UNIT. He meets a bloodsoaked couple with strange ears who ask for help and disappear, after which a man with a sword comes looking for them and departs when the alarm rings. Harry heads to the address that the couple mentioned, 17 Foxworth Drive.

In the 2010s, Harry and Naomi are working for UNIT after the Fourth Doctor returned them to Earth more than thirty years after their own time. Harry decides to investigate the matter of elf-like creatures encountered by Harper and a woman behind a vanishing wall in Clerkenwell tube station, believing them to be connected to the massacre at 17 Foxworth Drive. Back in the day, Harry had reported the bodies he had found there to the authorities, but the house had completely vanished by the time they arrived and the house numbers reshuffled. He looked into it and came into contact with the Brigadier, who hired him as UNIT's medical officer.

Harry and Naomi go to Clerkenwell and speak with Harper and the woman, who describe the sense of dread they felt as they approached the wall and show them the patterned tiles they found on the other side. They see the swordsman chasing the foreman over a monitor and Naomi calls the police whilst Harry goes to help, but the foreman is shot in the arm with an arrow. The swordsman recognises Harry and prepares to throw him in the path of a train before the Seventh Doctor uses the Sigil of Tormiss to bind him and force him to release Harry. The swordsman gets on the moving train as it passes.

The Doctor realises who he has just saved and is surprised to see how young Harry and Naomi look. Having read the UNIT files, the two of them know who he is and tell him what has happened.
