I remember reading a book in primary school that was based in I think a summer camp, and people kept dying one by one. There was someone called Isabelle and someone called Mike I think, Isabelle was poisoned and I remember someone also being locked in a freezer? I think there might have also been a bit on rock climbing? I don’t know if anyone can help me out, it’s been bugging me for years!
