I'm sorry I can't directly recommend reviews as I don't know which is his last novel. But you could start by looking at literary review websites like Goodreads or The New York Times Book Review. Search for Maugham's novels and then look for the ones that are considered his last, and there you'll likely find reviews from readers and critics alike.
I don't know the specific last novel of Maugham, so I can't recommend exact reviews. However, you can try searching on Amazon. Even if you don't buy the book there, customer reviews often give a sense of what people liked or didn't like about a book. Also, look for literary journals dedicated to English literature. They might have in - depth reviews of Maugham's last novel if it's a well - known work. Another option is to join online book clubs or forums where fans of Maugham might discuss and share reviews of his works, including his last one.
