"Michael, 'tis passing strange that you should be the first to mention that which I have brought you here to speak of, but, having done so, the need for a preamble is at least removed. Know, then, that the tale of the Black Box, albeit so bedecked and garnished with absurdities by the tongue of busy gossip, is not entirely fabulous. For, verily, that box exists. I have it here."
