Intrepid eight-year-old detective Nancy Spector and her talking dog, Jinx, search high and low for an invisible dog in this laugh-a-minute, fast-paced graphic novel perfect for fans of  Dungeon Critters  and  The Mighty Jack . The Invisible Man has a problem. His dog, Spot, is missing. Complicating matters, Spot is also invisible. So the Invisible Man turns to Nancy Spector for help.

And Nancy  knows  she's a great detective. Now she just needs to crack the case. . .   There’s no mystery here—this is one inspired, poignant, and imaginative tale.― Kirkus Reviews Stephen W.
