Pigeon Post (Swallows and Amazons)

Arthur Ransome's Swallows and Amazons series has stood the test of time. Ransome is not only a great storyteller, writing from first-hand experience, but each story celebrates eternally valuable qualities of practical knowledge, independence, and initiative. The twelve books are for children or grownups―anyone captivated by a world of sailing, adventure, and imagination.
The crew’s on holiday for their sixth adventure, and they turn their energies to mining for gold, aided by pigeon messengers Homer, Sophocles, and Sappho. The adventurers comb the nearby hills for a fabled lost claim, while being shadowed by a mysterious figure they dub “squashy hat.” Undeterred by drought, sudden brushfires, and the continuing presence of Squashy Hat, the young prospectors persevere in their quest―with surprising results. Full of the dangers and dark adventures of old mines and forgotten claims, Pigeon Post has an irresistible appeal to the persistent explorer in all of us.
