This novel caused Adams to become acquainted with the well-known scientist Richard Dawkins. As Dawkins explains, "As soon as I finished it, I turned back to page one and read it straight through again – the only time I have ever done that, and I wrote to tell him so. He replied that he was a fan of my books, and he invited me to his house in London." Adams would later introduce Dawkins to the woman who was to become his third wife, the actress Lalla Ward, best known for playing the character Romana in "Doctor Who". One of her early serials on the programme was "City of Death", which Adams wrote, and which shares certain plot elements with the novel.
