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 that tunnel 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.
