How Now Purple Cow

What could purple cows and elderly spies possibly have to do with each other? When young Mikey Cross discovers ceramic purple cows, a ring, and investigative notes left by a mystery writer popular in the 1950s, his parents' and grandparents' lives are turned upside down. Pamela and Chris Cross become involved in vintage intrigue with trepidation and more than a little angst when they find out there's an elderly assassin on the prowl and the situation isn't quite as vintage as they thought. The dead just may come back as the living when it's least expected.
