Jennie Levinsky can hear what her neighbors' sheepdog, Sam, is thinking -- and the junk-food-loving dog detective is thinking up more misadventures in this fast-paced, funny mystery. Sam: Dog Detective thinks there's a mystery brewing right next door! Three very odd women have moved in with a house full of caged animals. What's more, a scary-looking man comes and goes at odd hours. Sam is convinced the new neighbors are witches. After all, those animals look so wretched they must be under a spell. Curiously, Sam isn't feeling well, either. Have the witches put a hex on her, too? Can Sam, together with Jennie and her best friend, Beth, discover the truth before it's too late?
