Children's author and illustrator Etienne Delessert tells the story of Eglantine Besson, the woman who became his mother, and of the glass that came to represent their relationship.
After encountering three witches, the warrior Macbeth waits to see if their predictions come true. Stung by ambition, Macbeth is persuaded by his conniving wife that the fastest way to fulfill the prophecy is to murder the king, which sets off a disastrous chain of events. As the tragedy unfolds, Macbeth's decisions lead to more ruin. He returns to the witches and believes that his future is secure but is he interpreting the premonitions correctly?
