Crime Explanation: Someone led Blue to the library because he always goes there. At the time where most of us where in the pool, Blue was the only person who did nothing. This was the perfect time for the killer to strike. The killer strapped the bungee cord around Blue's neck and used the board to make him hang over the pool. At the perfect time, the killer chopped the board off making Blue fall down and snap his neck. This not only explains the board in the pool but the missing wooden board from the library. Also, to make it so Blue couldn't escape he cut Blue's throat so he would become weak.

Killer Guess: My guess has to be Wisteria Jr. because there is a knife in the book called " Cutting Edge Tricks for Sharp Cooks". Wisteria's job is a cook therefore making it possible that Wisteria did the murder. Since she is a skilled cook, she successfully managed to get no blood.

i think the murdurer used a knife to cut a hole in the board, tie the BC to it and the rope, and used the rope to stragle blue by hanging him above the pool. but the board snapped and they all fell into the pool. my best guess is Wisteria Jr because of the book having the word "cooks" in it, and she's a cook

I think... I am almost died... AND I think Wisteria jr. the killer because there is the "cooks" word on a book and she is a cook.

I mean abaut the "alomst die", I am almost in the danger zone...
