I tried another few times before finally giving up. The door-opening mechanism had seemingly been disabled.Lowering my shoulder, I drove it into the wall. I heard a soft thud. My shoulder started to hurt.As I yanked myself away from the wall, tiny pieces of concrete came with me, leaving a small gap in their wake.“Maybe we should look at the rest of the tunnel first,” Beverly said. “I’d hate to see you injure yourself trying to find something that’s not here.”“It’s here.” I jabbed a thumb at the wall. “You can see the concrete for yourself. This section’s different.”She sighed. “I guess I’m not sold on your theory. How could the Sand Demons just cover up a side tunnel? Wouldn’t other people notice that it suddenly disappeared?”“If there’s a tunnel behind this wall, it’s nothing special. Most likely, it was only partly excavated and never used. The kind of tunnel that wouldn’t attract much attention.”She knelt down and felt around in the water. “I don’t feel any tracks leading to the wall.”“If you were trying to eliminate all evidence of a tunnel, would you leave the tracks behind?”She removed a knife from her waistband.
