This prologue describes events that occurred in the lives of Charles Dickens, Charles Darwin, and Benjamin Disraeli in the summer of 1858. The publication in November 1859 of Darwin's groundbreaking Origin of Species, had its catalyst in June 1858. That was when Darwin, fearing that he might lose precedence by continuing to delay publication of his painstaking researches, was galvanised into writing up his findings quickly and having them published in one readable volume. For Dickens, the summer of 1858 was one of horror. Aged forty-six and already the famous author of several successful novels, he lost his head and publicly advertised his separation from Catherine, his wife of twenty-two years, while disclaiming rumours of a relationship with either his sister-in-law or an actress aged nineteen. He acted impulsively and brutally, losing friends, dismissing his publishers, causing anguish to his wife and children. As for Disraeli, he became chancellor of the Exchequer in Lord Derby's reforming Tory government.
