I wholeheartedly-on-the-edge-of-my-seat-and-check-a-third-time-that-the-window-is-latched-can't-stop-won't-stop loved this novel.
Having read THE WOMAN IN CABIN 10 and THE DEATH OF MRS WESTAWAY, I am familiar with Ruth Ware's writing, but they both failed to ignite me in the way that this book did. I was with Rowan from the very first page. We know she is in jail for committing a murder, probably a child in her charge as a nanny at Heatherbrae House, but we don't get the full story until literally the last few pages. Quite the slow burn. BUT that doesn't mean that this novel isn't full of creepy moments, the "smart" house is one giant danger zone, and there is a garden that is the thing of nightmares, and dodgy characters, the groundskeeper/handyman, cleaning woman, and neighbor all come to mind.
There is nothing formulaic about this book even though it falls strongly into a gothic mystery category. Ware's writing kept me guessing, and I was very satisfied by the ending. WHY DIDN'T I PUT THE PIECES TOGETHER? She definitely lays them all out there for the reader; it's up to you to put them together correctly.
THE TURN OF THE KEY puts me solidly in Ruth Ware's corner. She has captured my heart with this mystery novel. Rowan is a woman I won't soon forget.
