The Botanic Hill Detectives return in their seventh adventure, and this time, it’s all about pirates. Macadamia Street: Hidden Skeleton by Sherrill Joseph is set in the historic town of Penzance in Cornwall, which is still full of secrets and smugglers’ lore. Teenagers Moki, Rani, and twins Lanny and Lexi are invited by the new owners of Crow’s Nest Grange to investigate fragments of what looks like a pirate logbook from 1723, found during renovations at the manor house. They make a gruesome discovery in the cellar, but that only adds to the mystery. What is the connection between pirates and the aristocratic family that used to own the house? Why are valuable treasures disappearing from the house, and why is someone eavesdropping on the detectives? 

The exciting adventures and discoveries in Macadamia Street: Hidden Skeleton unfold against a perfect backdrop with the Cornish manor house and the seaside town of Penzance. Sherrill Joseph has done her research carefully, and the details of the location and its history, police and detective procedure, forensic anthropology (with one amendment), and genetics make the story even more compelling. The book is full of references to famous pirates and to literary works by Stevenson and du Maurier, serving as an introduction to the region's history without feeling like a school lesson. Wonderful characters like Captain, the former police dog, and Salty Joe, who knows everything about pirates, and a fast-moving plot will keep you riveted. Teens will love this book, as will anyone who enjoys all things piratical. Highly recommended.
