Agatha Christie is at the heart of this 20-euro coin, depicted as a pensive writer, fountain pen in hand, fingers forming the gesture of a revolver. Her portrait is surrounded by iconography drawn from her masterpieces: the mysterious island of *Ten Little Indians*, the manor of *The Murder of Roger Ackroyd*, the *Orient Express*, and the Nile with its pyramids. Every detail embodies the queen of suspense's criminal universe. The reverse features major philosophical quotes from Voltaire, Dante, Shakespeare, and Nietzsche, engraved around a central feather symbolizing the art of writing. Struck in solid silver, this collector's coin belongs to the "Art de la Plume" series and bears the signatures of engraver Joaquin Jimenez and the engraving workshop.
