Near the banks of the river Arno, in an upper room of the beautiful old palace of the Grifoni family, Beppina, the twelve-year-old daughter of the Marchese, lay peacefully sleeping. In his own room across the hall from hers, Beppo, her twin brother, slept also, though it was already early dawn of Easter Saturday in the city of Florence, and both children had meant to be up before the sun, that no hour of the precious holiday should be lost in sleep.
