Agatha Christie- And Then There Were None….?? Help me!?

I need help figuring out what to do to really get going in the game! My last question about it didn’t get any of the results I was hoping for, so I’m asking again lol. Ok so far, I copied down the rhyme from above the fireplace, I looked at the radio, I went into the pool room and tried to talk to those 2 guys, I went to every room upstairs and talked to almost everyone, I got the pack of matches, I got the walking stick, I got those two guys document things, and I guess that’s it. I can’t figure out what to do next to move on in the story! I have just been wandering around the house for like an hour trying to figure it out lol. Can someone help me?? Oh by the way, this is the game for the wii. If you can’t help me, can you at least give me a link or something to a good walkthrough? I just need help getting started. I was searching for walkthroughs, but I couldn’t really find any. Also, I don’t own the book or the movie, so please don’t tell me to refer to those! Thank you!
Please someone help me!!!! I can’t figure this out!! Is the PC one the same as the wii one?
