" This book is really pretty different than the first two in the series. The setting is different; we are now in England rather than in Chicago. And the kids don't work together as much. Instead Calder is MIA for most of the book, which is kind of too bad because he's my favorite of three kids. The premise is that Calder and his dad take a trip to England. They are staying in a small town that has recently received an anonymous gift of a Alexander Calder stabile. The town, however, is not a huge fan of the sculpture. Then one night, the sculpture and the boy of the same name disappear. Petra and Tommy come to England to try and help find their friend. The adults figure that the two kids would know best how Calder thinks, and that's how the author justifies their trip to England. I did like how Mrs. Sharpe is, as always, somehow involved in these cases. However, when the dust settles, I'm afraid the book really lacks foul play. "
