David Pinner is not content. A 35-year-old English teacher in a small private school in Marylebone, he isn't a writer or a boyfriend or a father. He isn't even a very good son. If he's not trawling pornographic websites, he's drinking with friends he doesn't really like or trying to avoid his neighbours. His new flatmate is James Glover, a barman whose life hasn't quite worked out either. And although he's a nice guy - a Christian and a small-town boy from East Anglia - he has certain fixed ideas about things.

Into the lives of these two dissatisfied bachelors comes Ruth, a successful American artist who taught David when he was an undergraduate at Goldsmith's. Ruth meets Glover on David's doorstep and although she's 48 and he's 25, a relationship begins. David, as mutual friend, puts himself in the middle of it, and his interest in the couple grows obsessive, and eventually destructive.

GLOVER'S MISTAKE is an exploration into friendship, jealousy and the mind of a modern day Iago.
