The Trees of Pride - G. K. Chesterton

Three trees, known as the Peacock trees, are blamed by the peasants for the fever that has killed many. Squire Vane scoffs at this legend as superstition. To prove them wrong, once and for all, he takes a bet to spend the night in the trees. In the morning he has vanished. Is he dead, and if so who has killed him? The poet? The lawyer? The woodsman? The trees? (Summary by Maria Therese)
