Amadeo Kaplan has two goals: to discover something very important, and to finally make a friend in his new town. So, when William (!) Wilcox (!) talks to him one day, Amadeo sees his dreams coming true. William could become a friend, and his mother organizes estate sales-perfect places for unearthing treasures. As Amadeo helps William and Mrs. Wilcox sort out an eccentric old woman's belongings, he comes across a valuable signed drawing. Amadeo's thrilled, but the drawing is only part of his ultimate discovery.
