This is the wonderful adventure story of Djuna, a young boy who uses his eyes and his head and his little Scottie dog, Champ, who uses his nose to sniff out clues. There is also Mr. Scissors, the traveling knife grinder, who is driving though the country in a wonderful caravan with his young granddaughter, Joan. There are also two wicked men who are cruel to Mr. Scissors, a reporter named Socker Furlong, and Miss Annie Ellery, who plays a surprising part at the end.
