The Trouble with the Tick-Tock Tabby
by Dawn Vogel
Chrysanthemum and Marigold Marsh, girl detectives, investigate a break-in at their family's mechanical garden, and discover the culprit is a mechanical cat. After learning that the mechanical cat has only a limited power supply, they must find the cat to return it to its owner. But Dover is a big place, and there are Built Boys, a carnival, and a man called Solomon standing in their way.
