3 out of 5 stars
One Little Secret? More like countless big secrets in this domestic thriller by Cate Holahan.
I picked up this closed-room mystery book during a BookBub special. The story centers around 3 sets of neighbors who ship their kids off to camp and spend a week together in Long Island. Soon after arrival, drama occurs and one of the wives turns up dead on the beach.
At first, the characters seemed so interchangeable, that I had a hard time remembering which spouse went with who. Once I got everyone straight, the story became more compelling. While some parts of the story were predictable, others kept me guessing. As the story unfolded, it was less and less believable that these couples, who seemed more like frenemies, willingly went on vacation together.

The subplot with the detective and her family added an interesting dimension to the story.
Although One Little Secret is not a book that will likely make a lasting impression, it was a great weekend distraction.
