"They won't roll over. Dodge, a retired plice dog, and Cassie, his girl, are perfect partners. Quick on their (six) feet, driven to help, and willing to break a few rules, the two are always ready for a new mystery. . . . When Verdel Ward, the town's richest man, disappears without leaving a will behind, everyone from the housekeeper to the major wants to get their hands on his fortune. But Dodge and Cassie smell a mystery - they can't help wondering about the suspicious fiancee and the twin brother no one's ever heard of. Who keeps tripping the alarm while sneaking around Ward's mansion? And why is the new dog at the animal shelter so afraid of clues from Ward's property? Together, Dodge and Cassie dig up clues and sniff out a trail that leads to a case much more sinister than a missing millionaire. Something's not adding up, and the pair might be in over their heads. But this dog and his girl always collar their culprit." - back cover
