This is the 3 they mentioned. It's exactly that. A purple felt 3. It's about 2 inches tall, and it's pretty flimsy. But I can't be bothered with it now. I need to know the answer to their riddle. I need the key to make it all make sense. There's only one more thing that came with the letter. It must hold the solution, the key, the answer. Dare I go on? I must.
