Sherlock Imagines

She's A What? (Part 5)-John

You quickly stopped at your flat and changed. You really didn't want to fight in a dress if you'd have to fight at all. You rushed back outside and gave the cabbie the address. You had also grabbed two of your guns and had them hidden. The cab stopped outside your destination and you recognized it as the warehouse that you got shot at. You took a deep breath and walked inside.
Your gun was clutched tightly in your hand as you snuck your way inside. You had no idea where John and Sherlock were but you were doing this all based on guesses. You walked down halls and opened doors. It was really dark but you could see pretty good. As you came down one hallway, at the end of it there were three doors. You heard a soft crunch almost from under your foot. You picked it up and looked at it. Another note.  This one read:

"As you see there are three doors here. In one of the rooms is where your friends are. You can only choose one so make your choice."

You dropped the note and stared at each of the doors. Only one!  Now was when your good thinking skills came in handy. You walked up to each door and tapped the code for 'help' that you and John had come up with. You knocked it onto the door and listened. Nothing. You then went to the door across from it and knocked. Once again nothing. You then tried the third door but still nothing. Then you heard tapping coming from the door next to you. You were about to open that one when you heard a loud thud come from the door across.

'It's a trick!'  You thought.

There weren't three rooms. There were three different doors that would eventually lead to the room with your friends. One of them was the quickest way though. You decided it wasn't the first one cause the tapping was distant. You went to the second door, knocked, and listened. There was an echo. So you chose the third one.
You opened it and followed the hallway that lead to a door at the end. You tried to handle but found it was locked.  That's when it hit you.  One of the doors had the unlocked door at the end!  You couldn't go back now though. You could hear people on the other side and knew you had to get in there. You put your gun back into it's holster and pulled out a lock picking kit. You bent down to the lock and began to work at it.
