Lemonia lives in the old Chalk Farm Tavern in Primrose Hill, which is better known as the set of Paddington. It is not surrounded by fields filled with duellists under a hill of primroses these days, but it is still vast, pale and beautiful: a survivor in the sprawl. There has been a tavern on this site for so long — it was first recorded in 1678 when a corpse was carried to it — that it is possible John Keats drank here.
