Giles examines some papers about the life of Sir Alistair — diary entries written shortly after he retired from his "soldiering". As told in those notes, the Brigadier, after retiring, goes spend a holiday in a "quaint village" in the Yorkshire Dales a week before he is due to take up his new job at a local public school. After moving into his lodgings at the Golden Fleece, he tries to enjoy the lush countryside. However, he keeps being reminded of the various horrors he faced over the years when trying to take quiet walks.
Hearing rumours that tourists have been going missing on the moors, he gives in to the temptation to investigate, thinking of it as "one last adventure" before he becomes a teacher. He locates a natural cave in the area where tourists have been going missing, and finds gruesomely mutilated human bodies inside. Keeping his cool, he begins theorising that this must be the work of some alien scientists trying to understand human physiology with particularly crude methods. However, when the dweller of the cave arrives, he is a thoroughly unimpressive, very-much-human man with an unstable disposition. Arresting the murderer, the Brigadier is told by the authorities that the man he helped apprehend was a perfectly mundane deranged serial killer, Harold Alton.
Although proud that he still managed to save lives by putting Alton back behind bars, Alistair Gordon Lethbridge-Stewart is left to ponder how his decades dealing with the supernatural have warped his perspective on things. He muses that although formally retiring was an important first step, he still has a lot more efforts to expend to truly put his old life behind him.
- Alistair Gordon Lethbridge-Stewart's old position was taken over by a man "hand-picked by the boffins at Geneva" following his retirement.
- The Brigadier finds a holiday to a village in the Yorkshire Dales "much preferable to being called to a quarry in Dorset".
- He recalls having once been posted in Sierra Leone, where a man "could go for days without meeting another soul".
- His writings mention "tales of Odysseus" which feature sirens who lured men to their doom with the sound of their voice.
- The Brigadier is familiar with the Drofen, whom he describes as "cannibals".
- Although the character could not be referenced by name, the Doctor is subtly alluded to: at one point, the Brigadier makes brief reference to his old "scientific advisor", singular, before talking about his scientific advisors in the plural in the next sentence. This echoes his lines "Wonderful chap, both of him" and "Wonderful chap, all of them" in the multi-Doctor stories The Three Doctors and The Five Doctors.
