From the bestselling, award-winning author-illustrator team of Doreen Cronin and Kevin Cornell comes the first book in a heavily illustrated, hilarious chapter book series about the adventures of a dog detective. Perfect for fans of Sara Pennypacker's Clementine series and Jarrett J. Krosoczka's Lunch Lady series. 

J.J. Tully is a former search-and-rescue dog who is trying to enjoy his retirement after years of performing daring missions saving lives. So he's not terribly impressed when two chicks named Dirt and Sugar (who look like popcorn on legs) and their chicken mom show up demanding his help to find their missing siblings. Driven by the promise of a cheeseburger, J.J. begins to track down clues. Is Vince the Funnel hiding something? Are there dark forces at work—or is J.J. not smelling the evidence that's right in front of him?

The Legend of Diamond Lil, second book in the illustrated J.J. Tully mystery series, is perfect for elementary-school kids who love adventure and animals. New York Times bestselling author Doreen Cronin brings the same wonderful humor to the JJ. Tully whodunits that she did to her beloved picture book bestsellers like Diary of a Worm.
 
In this sequel to the chapter book The Trouble with Chickens, all search-and-rescue dog J.J. Tully wants is to enjoy his retirement. But mama chick Moosh and chicks Dirt and Sugar are acting strange. A possum keeps finding its way into the chicken coop. And J.J. has questions about Diamond Lil, the fancy new dog next door. He’ll have to track down the clues and sniff out the evidence to save the day.
