I'm giving away the plot line, but you were supposed to all be innocent and the sus guy was going to be the one who betrayed you, so it wasn't really a MM at all.
Reminds me of what @Mark12291229 told me one day
"11 men are stuck in a room, 10 are gay, one is straight. Gay guys have to find the straight guy, and straight guy has to be unfound.
Plot twist : they're all straight"
