Yes, a re-read, but I now own a copy. Found it at the library book sale and simply had to have it. In fact I snaffled it as I was unpacking the books, that's how much I wanted it. And I'd finished it by tea-time.We had a desert island discs conversation, but books & this is on my list. Just a sparkling good read, a simple surmise, but so well plotted that the ending takes my breath away every time.
