Stay Alert

We found a little alcove in the tunnel. It was only a few feet wide. But it proved a nice refuge. We pressed our backs against locked door and rested our tired eyes. Well, Freddy, Norm and Olivia did. I stayed vigilant. No one asked me to. In fact everyone else somehow agreed that there were no threats underground. But I couldn't do that to them. I had to stay alert. I knew something was out there. Hours would pass by untill I had a hint of an idea, and then I heard it. It was faint whistle, but unlike a train or anything I had heard before. I jumped to my feet and ran in the direction of the strange, new sound.
