And not just any contestant's entry?Sophie's! Sophie is Lark's best friend (she just doesn't know it yet). The twin sleuths can't simply roll with it. To save the contest they'll have to take a whisk risk and start investigating the other contestants. With the timer ticking, Lark and Connor have to find the culprit before someone actually takes the cake. Lark and the Dessert Disaster is the fourth title in the Lark Ba Detective series, following Lark Holds the Key, Lark and the Diamond Caper and Lark Takes a Bow.
