An open window. An empty velvet box. One very curious cat.

In the cozy town of Whiskerville, Mrs. Hargrove’s most treasured possession, a silver necklace set with a single blue sapphire, vanishes overnight. All that’s left behind is an open window, a stirring curtain, and a little velvet cushion where the necklace used to be.

Luckily, Whiskerville has Nina. She’s a gray-and-white cat with bright green eyes and an even sharper nose, and she notices the little things everyone else walks right past. With her best friend Emily and her bouncy little helper Paris close behind, Nina follows every clue through gardens, over rooftops, and past more than one suspicious whisker, until she uncovers the truth.
