Now You See Me

My name is Matthew McConnell. You've probably heard my story. I took five of my friends on a boat through the longest canal tunnel in England. It takes two hours and twenty-six minutes to travel through that tunnel. Six of us entered, but I was the only one to come out. It was pitch black in there - I don't know what happened to them. But I'm the only suspect. And if I don't find out how they disappeared, I'll be sentenced to murder.
