DISK3A.BMF

An unlabeled 3.5-inch floppy disk. It arrived at the station in a plain brown envelope addressed to Detective Brawley with no return address. Brawley had the envelope and disk dusted for prints, but nothing showed up. Now he’s with the tech guys, watching them carefully insert the disk into a PC. There are a few files on it: readme.txt and a series of jpegs. They open the readme and find a single line of text, in all caps: CHANGELINGS STAIN THE WORLD AND IN CRIMSON I SHALL STAIN THE CHANGELINGS
