There is more than one author with this name

The majority of the books that Lewis wrote or edited, often jointly, were nonfiction and closely related to his journalism. However, he is best known for his 1960 novel The Evolution Man, which went through six editions under a number of titles. This comic novel purports to be a first-hand account by the son of the first man to discover fire. To prevent further 'advances', the family takes matters in hand, leading to a conclusion given away by the book's eventual subtitle, 'how I ate my father'. Continuing authorship into old age, Lewis published a second novel in 1990, the same year that a play of his on William Shakespeare was performed in the Edinburgh Festival Fringe[1], followed by a novella in 1991 and a further novel in 1995. All three of these later fictions were provocative reinterpretations of Victorian times.
