From the streets of Edwardian London to the corridors of a near-infinite library in the distant future, a single book holds the key to the fate of life on Earth. Some believe it predicts our future – and the apocalypse - with unnerving accuracy. Others will stop at nothing to destroy it, and will chase it from one side of the universe to the other; from a country house in the Roaring Twenties to the casinos of Mars, and from 221B Baker Street to the terrifying desert world of Sisyphus IX... Featuring Abby and Zara [Graceless], Sherlock Holmes, Dorian Gray, Iris Wildthyme, Vienna Salvatori and Bernice Summerfield, The Worlds of Big Finish brings together some of Big Finish’s best-loved characters in an adventure spanning thousands of years! This release includes a fourth bonus disc - Round the Worlds - where director Scott Handcock leads a roundtable discussion with writer and cast about this special adventure, plus a selection of outtakes from recording.
