Nobody Stole the Pie

The town of Little Digby had at its heart a beautiful lollyberry tree and each fall the town bakers would pick the berries and make an immense pie for the whole village to share. But overnight, as it was cooling in preparation for the next day's celebration, birds, animals and people would take just a crumb, or a single berry thinking their bite was too insignificant to matter. However, come morning, when the wise mayor went to distribute the pie it was all but gone. So? Who stole the pie?
