Nightshift 40 - M-A Hallway
[From here]
Dean stopped long enough to count down the rest of the individual halls. He might not have the fancy college education Sam had, but he was pretty sure he could remember a map without any problems. The layout so far was ten rooms to each hall, and about four halls total, making this block about forty rooms. That meant that the hall he wanted, where M31 was, would be the last one down. Dean kept a good grip on his bowie. He headed down the corridor, turning left at the last hall and headed resolutely toward M31.
