At first this seemed like it would just be an ordinary locked room type mystery, but boy was I wrong. There was nothing ordinary about the characters or the plot. It took a while to get to know all of the woman who were essentially stranded on an isolated island in Scotland. And it took even longer for each to slowly reveal what horrible thing they might have done, and which might have made them the target of the killer who is holding them hostage. The surprises just keep coming and even though each woman has done something horrible you can’t help but like the fact that in the end forgiveness and friendship triumphed. Listening to the audio version was perfect. Each character had a distinct voice and not being able to skim ahead made the suspense even better.
