Yashoku smiled when he was Alger getting ready to punch the door.  He reached into his pocket and pulled out a needle and thread.  The thread was just thin enough to have a shadow that he could move across but was still hard to see.  He put the needle on the floor under the door with one finger barely sticking out of the shadow.  When the punch came he gave the needle a quick flick that sent it across the floor along with splinters.  He then quickly moved along the string’s shadow to the needle’s shadow.  It was very cramped inside because it was so small.  He knew that he couldn’t stay in it for long but he just had to wait for Alger to enter the room.
