Two “stolen” notebooks written by Charles Darwin have been mysteriously returned to Cambridge University, 22 years after they were last seen.
The small leather-bound books are worth many millions of pounds and include the scientist’s “tree of life” sketch.
Their return comes 15 months after they had gone missing and the library launched a worldwide appeal to find them.
The university’s librarian Dr Jessica Gardner says the books were returned anonymously in a bright pink gift bag containing the original blue box the notebooks were kept in.
