John Brent's quest for the monsters in Lake Kingswater now seems absurdly unimportant compared with what he has discovered about Professor Cato. The fate of the dinosaurs seems irrelevant when the fate of mankind is in the balance. Yet in an astounding manner the survival of man is vitally affected by the survival of the monsters.
