One entry from her list of the greatest twins in children’s books, as shared at the Guardian:
Claude and Eustace Wooster, in PG Wodehouse’s The Inimitable JeevesRead about another entry on the list.
Claude and Eustace are the literary precursors of Rowling’s Weasley twins. They create chaos at every turn, and inevitably drag with them their hapless cousin, Bertie Wooster. Even when Claude and Eustace are supposed to be studying in the countryside, they do a sideline in taking bets on the sermon times of the local clergy. Usually partners in crime, their mistake is to compete for the love of the same woman, a division that Bertie’s brilliant butler, Jeeves, is able to exploit in order to outwit them once and for all.
Claude and Eustace Wooster are among John Mullan's ten best identical twins in fiction.
