Middle-grader Saxby Smart is back in his Thinking Chair for three more stories in this second volume of his mystery series (The Curse of the Ancient Mask and Other Case Files, 2009). Speaking congenially to readers, Saxby invites them to help deduce the clues. In the first case, Saxby must find a rare comic book that’s gone missing from a locked safe, and he uncovers lots of interesting comic-book trivia in the process of discovering the motive—old-fashioned greed—and the perp. The middle is the most engrossing of the three stories, involving an historic mansion with a dark past where Saxby’s friend finds a scroll hidden in the wall that leads them on a brain-teasing hunt to the real “Treasure of Dead Man’s Lane.” Last, Saxby must unravel the enigma of six students who all have two things in common: home intruders and an anti-stress class. Troublemaker Harry Lovecraft makes a reappearance, and his uncle plays a key role in the mystery. Generously dappled with Alley’s breezy line drawings, the cases are timely and twisting enough to keep the light bulb bright in the young sleuth’s mind. (Mystery. 8-12)
