Keith’s uncle and Auntie Dee’s husband, who is an air force officer supposedly away at war, but is actually hiding in a field. He is glorified in the novel for his participation in the Royal Air Force, and his service is a point of pride for Auntie Dee. Stephen explains that she even mirrors his person with her messy home and reckless yet cheerful personality. It is implied that Uncle Peter has deserted his post in the air force, most likely due to PTSD (Post Traumatic Stress Disorder) or his discomfort in being involved in the British bombing efforts, which were controversial for their indiscriminate targeting of civilians. However, as Stephen notes, Uncle Peter is still glorified in the Close for his participation in the war, making his desertion all the more disappointing and important to be kept secret. In Uncle Peter’s interactions with Stephen, it is revealed that he has loved Keith’s mother from the very beginning and hints at the fact that they are involved in a secret affair.
