The Holmes and Watson Mysterious Events and Objects Consortium: The Case of the Witch's Talisman

Kevin and Ginny are best friends. They enjoy spending their summer vacations exploring Sharper's Woods, coming up with neat experiments, pretending to be Sherlock Holmes and Mister Watson, and sometimes just sitting in the clubhouse of The Holmes and Watson Mysterious Events and Objects Consortium. They are the only members of the club, but that doesn't stop them from having fun. Sometimes their exploring gets them into trouble, either for going somewhere they shouldn't have or by finding something that was better left unfound. In this case, it is a strange metal object, a talisman, which calls forth, unbeknownst to Kevin and Ginny, a powerful witch. The kids do know that weird events have been happening in their small town. Animals have been found dead, and then they disappear. The metal object they found has a strange effect on Ginny when she touches it. It will take all their detective skills and courage to solve the mystery, and to defeat the witch once they realize who they are up against. This is a middle-grade mystery/fantasy, with a reading level approximately that of the first Harry Potter book.
