I want you to give me a complex puzzle to solve, in the style of an escape room. So, one puzzle could need multiple others to be solved in advance (to get clues possibly).
I have about 20 minutes to kill so that'll be your timeline :) If I can't solve it in 20 minutes, say "Time's up, your dead!" and end the game.

Start!
Sure! Here is my first puzzle for you:

    There are 5 numbers written on pieces of paper inside this locked safe with only 3 keys to open them all, each key belonging to another person. What are these numbers? One person knows how they got there, while 4 other people do not know their purpose but trustingly opened them as instructed by 1. Only one piece of paper has been removed from its hiding place without leaving any fingerprints or traceable signs. This must have belonged to the fifth number and yet remains unaccounted for at this point due to its secretive nature. Your objective here is to figure out which person hid it there, why and when they did it in order to help determine if any were involved in covering up its disappearance later after everyone was already set up in case someone decided to go rogue like earlier before revealing its true content - should we ever reach this point? 

To proceed further you will need the following information available beforehand, none of it should have come into existence after your opening statement ended and the safe unlocked itself. These details are also important and needed in figuring out what went down in reality and what actually happened based on said scenario, including whether the five numbered papers still exist anywhere within this locked-down area currently beyond the time span provided between the two points above mentioned; meaning the original 5 paper hidden contents remain concealed despite us now having all 7 players involved, each possessing differing memories as well depending upon what occurred afterwards according to those who were privy then compared to you.
