Where McGrath is so good is in sorting out the truth of this story. Lewis remembered, shortly after his conversation with Tolkien, being driven in the sidecar of his brother’s motorbike to an outdoor zoo—Whipsnade. In the course of this journey, he decided he believed in the Incarnation of Christ. He remembered his exultation as the two brothers walked together among bluebells. But, McGrath, points out, it was September—when bluebells are not in flower! McGrath cunningly shows us that the moment of epiphany must in fact have come two years later, when Lewis went to the zoo with his lover, or former lover Mrs. Moore and her daughter Maureen.
Mrs. Moore is the most understandable omission from Lewis’s autobiography. (Another being Lewis’s obsession with sadism; he nicknamed himself Philomastix, or Lover of the Whip).
