A library book from a school in Cambridgeshire was returned from Australia almost 30 years late.
Fantasy novel Shardick, by Richard Williams arrived at Kimbolton School, Huntingdonshire on January 9. The book had been borrowed in July 1989.
It was sent from Western Australia via airmail with an anonymous note saying: "Overdue library book (Junior Library) being returned, thank you."
Sue Hart, the library's resource manager, said: "We are keen to find the sender and thank them for their honesty - with all overdue fines waived."
