Action, adventure, and time travel combine in the final book of an award-winning trilogy. Narrowly escaping from a gang of bullies, a boy slips into a grand old gallery--the perfect hiding place, full of mystery and treasures. Suddenly, a painting comes to life and the boy finds himself on an adventure led by a mischievous dog that has leapt from the canvas. The two slip into a Vermeer painting and are transported to Little Street, Delft in seventeenth-century Holland, where the boy has to use every ounce of his ingenuity to rescue his new friend from an untimely fate.     The third book in the "Boy, Bear" series, The Hero of Little Street is packed with thrilling escapades from start to finish. Gregory Rogers's cast of much-loved characters come together once again in this triumph of visual storytelling.
