The shed in the darkness

Once upon a time there was a boy called Bruce and one day he came across a shed.  For many days he just ignored it, but one day curiosity came to him.  He had to open it, but did he dare go in alone!  The answer was no, so he got his friends Jane, Jim and Lily. One day they were at school when they saw the door open.  They were trying to see what was behind the door, but they couldn’t see what it was.  After school they went to investigate it when the door opened and they were never to be seen again.
