Based on Dickens's and Collins's walking tour in the north of England was serialised in Household Words in October 1857.
Collins was a lifelong friend of Charles Dickens. A number of Collins's works were first published in Dickens's journals All the Year Round and Household Words. The two collaborated on several dramatic and fictional works, and some of Collins's plays were performed by Dickens's acting company.
Collins predicted the deterrence concept of mutually assured destruction that defined the Cold War nuclear era. Writing at the time of the Franco-Prussian War in 1870 he stated, "I begin to believe in only one civilising influence — the discovery one of these days of a destructive agent so terrible that War shall mean annihilation and men's fears will force them to keep the peace."
