The shaggy-haired man eyes the bench where Robbie sits.
"Can I help you, sir?"
"Would you mind standing for a moment? I need to photograph this bench." He explains his grand scheme: a comprehensive illustrated survey of the public benches of Oxford.
Robbie shrugs. No harm in humouring the bloke. He's sitting down again when James arrives with their coffees.
"Who was that?"
Robbie explains. "He seems to think it will be a best-seller."
"Of making many books there is no end," James quotes.
Robbie smiles indulgently. The most important thing about a bench is who you share it with.
