Book Description: In this clever chapter book, the third starring Drake Doyle and Nell Fossey, real science is seamlessly woven into four exciting cases, including the appearance of a spooky ghost and the rescue of a classmate wedged in a laundry chute. The snappy dialogue and wacky scenarios are perfect for middle-grade readers, who will enjoy discovering the appendix of science activities. Each activity corresponds to a case in the book and will have readers scrambling for their own magnifying glasses and ghost-detection gear! Illustrated by Barbara Johansen Newman
