"A truce, huh? Sounds like that might be a hard sell." It was true that most people wouldn't normally resort to murder, but considering that Rio had apparently left the others to drown, it would be easy for tempers to flare.

And if someone was really, truly determined to kill Rio, there was very little any one of them could do about it. Many of the puzzle rooms were already death traps. Plenty of opportunity for a seeming slip-up.
