I am 70 now and have been an avid book reader all my life. I enjoy being pleasantly surprised how an author tidies up a book with a satisfying ending. But with this novel, I figured out the ending in the first chapter & hoped like heck this was not true. This hope kept me going since the book is wonderfully written and I genuinely felt for the character. I thoroughly enjoyed the authors listing of all the old and wonderful mystery books which I am mostly familiar but intrigued by more than a few others. It would have been helpful if the author has listed all books referenced in the story in a special section at the end of the book.
If this had been the first or five hundredth 'who done it' I read, perhaps i would be pleased with the ending but i wasn't. I was so disappointed.
Also, i feel some stuff was redundant' padding to move the story forward or lead as astray - there are gaps where some murders should have been solved much quicker. It moved chunky at some points. Excellent premise. But too old formula to all the books he mentioned but maybe that was the authors intention.
