Cruise Ship Kid: Thief At Sea!

There's 4 things you should know about me:
1. I live on a cruise ship
2. My name is Silver. Yes, really
3. I've never had a best friend my own age :(
4. I'm definitely not a detective

Somehow, though, I'm now investigating the CASE OF THE MISSING MEGA-EXPENSIVE WATCHES. But, I've got a plan. If I can solve the crime, then surely the kids on board will want to be friends with me. Right?

I've had lots of help (interference) from the Gang, but I won't tell you about them because they are all over 80 and prefer playing bingo to solving crimes.
