Or maybe the "Mole" doesn't even know they are a mole, what if someone bugged the lab? its possiblity, in which case the "character" can always say "Hey i didn't do it" and be telling the truth, but then someone plays a tape and there is their voice.
This would give a whole knew mystery to why someone would go to all that trouble, why that person, who are they after and so on. Just another thought.
