Fire Storm — Andrew Lane

In Fire Storm by Andrew Lane, young Sherlock's friend and her father have vanished. Their house looks as if nobody has ever lived in it; the neighbors claim never to have heard of them. Sherlock begins to doubt his sanity, until a clever clue points him to Scotland. Following that clue leads him into a mystery that involves kidnapping, bodysnatchers, and a man who claims he can raise the dead. Only the budding detective Sherlock can untangle the mind-bending--and dangerous--puzzles that ensnare his friends. Think you know Sherlock Holmes? Think again!
