"A scrappy stray mutt with a "ruff"-and-tumble vernacular winningly narrates this snazzy mystery caper. Van Draanen sustains suspense as the sisters navigate clue-filled riddles and secret passageways, uncover long-lost treasure, and outwit a nasty trio of thieves."--Publishers Weekly

"A stray dog who "nose" his way around detective work helps two sibs find and fetch back their "dadnapped" father in this breezy caper. By the end, the slobbery sleuth will have won over readers just as he does the Nanigan clan." --Bulletin

"A lovely genre introduction, perfect for those starting out to enhance reading comprehension with and enough fun to keep seasoned readers engaged." --School Library Journal
