Gr 4-6-- An expedition of scientific experts have come to Scotland to capture a beast residing in the lochs. However, even with all their sophisticated machinery, they are faced with only false alarms and fuzzy pictures. Then the experts' children get involved. Mary, Scott, and Theo decide that the summer would be more exciting if the National Geographic TV crews came, and manage to create a creature that fools the infrared cameras and the experts. Of course, the real monster later emerges. The book begins slowly, with a minor mystery falling flat when it builds too long and then is so predictably solved. But the pace picks up once the children begin their plan. The adult characters, both benign and evil, are mere cardboard creatures with little life or interest. In contrast, the children are well - developed with normal abilities and interests. They are understandably bored with the plans the adults have made for them, so they use their imaginations to create a more exciting summer. Not quite a mystery, sort-of an environmental book, and generally a good read. --Karen K. Radtke, Milwaukee Pub . Lib .
