We don’t write them quite as often as we used to, but a well-crafted letter can be a real treasure. There’s something intimate about opening an envelope addressed to you and unfolding the paper inside to find the letter writer’s unique handwriting, unique voice, little drawings. Plus anything they might have dropped into the envelope as an extra surprise—a pressed flower, a photograph, a folded up twenty dollar bill. Letters can carry gossip, jokes, professions of undying love…and of course, letters can carry secrets. And in the story we’re about to tell you, a letter was the key to unlocking a mystery so dark, so poisonous, that no one who read it would ever be quite the same again.
