What is the theme in Cakes and Ale: Or the Skeleton in the Cupboard by W. Somerset Maugham?

Religion comes off rather shabbily in Cakes and Ale. Narrator William Ashenden is raised in the Blackstable village rectory by a strict aunt and uncle. He recalls Sunday morning rides to church and being admonished to behave properly in his pew. His aunt, belonging to an impoverished noble family of Germany, cannot abide the working classes—although she is otherwise a devout Christian.
