Age: (in 1977): 30

Home: Clapham, South London.

Family: We are not told. He doesn’t mention anyone apart from his ‘dead aunt’s sofa.’

Appearance: Unclear. There is mention of spectacles and a duffle coat.

Interests: He attends a chess club and watches TV. Apart from that, his interests seem only to revolve around the adventures he relates in the book.

David is certainly obsessive. He is not one to let go and move on. Because there is no evidence of friends or lovers, his social skills are non-existent.
