I did my book talk on The Mystery of the Biltmore House by Carole Marsh. It is about four kids: Stacy, Wendy, Trent, and Michael. Their parents are at a writing workshop at the Biltmore House. Napoleon's chess set has gone missing, and it is Stacy's job to find it. The other three just tag along and act like they are interested. This book is full of clues and even missing children! I highly recommend it!
