Down the corridor to the right

You followed Linda down the corridor to the right.  It was a typical university corridor.  It was about eight feet wide.  The walls were cement blocks that have been painted off-white.  The dropped ceiling had fluorescent lights about eight feet apart.  It had doors on either side at regular intervals, about every eighteen feet.  About halfway down were a pair of doors that led to the restrooms.  At the far end, the corridor turned to the left with a set of doors that led to the outside on the right.

Like most bureaucracies, the university labeled the rooms in a purely functional manner.  It started with the first letter of the building?s name.  That was followed by the floor number.  In this case, a ?1?.    Finally, the rooms were numbered from 00 to 99.

Since Linda was leading you down this hallway, it was safe to assume that Cindy had come down this way.  The question was where did she go.  You doubted that Cindy came this way to use the bathroom.  Most of the doors were open but every one of them was dark.  The classroom that each of them led to was obviously empty.  Still, there were a couple doors that are closed.  It was impossible to tell what lay behind each of them.  She could also have turned down the corridor to the left.  She could even have gone out the door.  You had to trust Linda to lead you to her.
