Strangers on a Train

Dear diary...
The good news: Bess, George, and I are on a train bound for Denali National Park, gazing at majestic Mount McKinley as we speed along. It's truly awesome! The bad news: Someone — a creepy passenger or a disgruntled employee? — is still causing major trouble on the Arctic Star cruise ship, and now that we're sightseeing on land, the danger has followed. Whoever it is has got even me in their sights — but I've been working undercover, so I have no idea how anyone discovered I'm a detective. With every step I take, I'm looking over my shoulder. The forty-ninth state sure is proving to be treacherous territory.
