We are initially thrown into the murky world of the squalor of Dickensian London complete with outsize characters and even a scruffy young boy, Jaffy, as the star of the story. But before long though we embark on an exciting adventure on the high seas hunting whales and capturing a 'dragon' to be shipped to London. Abruptly though the pace changes as things don't go to plan and in the darkening mood we fear for the life of our hero.
