The analysis Claude J. Summers writes of Forster's work, the novels, short stories and essays is detailed and revealing. He relates elements of the books to Forster's life and personal experiences and shows how they build on one another as a body of work. It's a book to read after reading the novels as naturally there are copious spoilers, and it can get quite academic at times. Still, if you're a big Forster fan it's a rewarding read. However, I went into the book wanting more biography of Forster rather than analysis of his novels, not Summers' fault, and I think a book like A Great Unrecorded History: A New Life of E. M. Forster will be more what I was looking for.
