Perfect for you if...

You enjoy mystery stories where kids do the detective work and piece together clues like proper investigators
You like the idea of Sherlock Holmes's legacy living on through younger characters who think logically and question everything
You want a book that's spooky enough to feel genuinely creepy but not so dark that you'll have nightmares

Maybe not for you if...

You prefer fast-paced action over the slower burn of mystery-solving and logical deduction
You're looking for paranormal horror where the monster is genuinely supernatural rather than having a rational explanation
You want stories about contemporary kids using modern technology like apps and social media to solve cases

About this book

Xena and Xander arrive in the country village of Blackslope for a vacation, but their plans are disrupted when a large monster begins terrorizing the town. The young detectives must work to solve a mystery that appears difficult to unravel. Their famous ancestor, Sherlock Holmes, investigated a case involving a beast in Blackslope nearly a hundred years earlier. Xena and Xander must determine whether the creature currently threatening the village could be the same one from that earlier investigation.
