The Dykemaster is the tale of a visionary young north Friesian Deichgraf of the 18th century, creator of a new form of dyke. The short-sighted and self-seeking community with which he is at odds turns him into a phantom, seen riding his grey along the dyke whenever the sea threatens to break through. The rationalistic storyteller, in a highly sophisticated narrative structure, belongs to a later age, and what he relates is a veiled critique of the dyke officials of his own day.
