“Have you ever wanted to become a Catholic?” Muriel Spark wrote to Derek Stanford on 6 February 1949. “I would if I could find Faith. I shall set out on a pilgrimage, I think, turning over small stones and leaves [...] searching for Faith.” The tone was light-hearted, despite the fact that she had just been sacked from the Poetry Society, and relations with her lover, the poet Howard Sergeant, were terminally acrimonious. In a sense she was converting from Sergeant to Stanford as her confidant and courtier.
