The Sign

Every teacher casts a shadow, and Zarathustra's has been trailing him since the day he first came down the mountain. This is where the series ends, with Clancy Martin facing that last companion: a wanderer who unlearned every value in the teacher's company and kept exactly one sentence for a creed. Then comes the book's final day, a noon, a festival in a cave, a donkey receiving prayers, and a morning that settles what the whole journey was for. Martin offers the plainest definition of a shadow you will ever hear, and the book saves one last joke, along with the question of who it lands on.
