Книга "Case of the Shady Shamrock". A mysterious package appears on Zack Anderson's doorstep. When he opens the crate, there's an elaborate silver chest, obviously quite old, with Celtic markings and no apparent way to open it. Zack is almost content to accept the artifact as a decorative item ... until people start coming after it. The only conclusion is that the box contains something of great value. Zack, Jillian, Sherlock, and Watson are on the case, tracking down the unusual item, learning tidbits about the box's history, and discovering that it dates back to an unsolved theft in Ireland more than a hundred years ago. Can Zack, Jillian, and the corgis piece together the clues and find out what's inside the little chest before it gets snatched from their hands forever?
