"Patients"

I'm writing this letter to make known my suspicions regarding a few "patients" that were recently admitted. I think that their paperwork was forged, and their afflictions are an act.
I've caught the individuals in question having hushed, but lucid conversations when they think no one is looking - only to slip back into their "insanity" act once they realize someone is watching. 
What I haven't figured out is ... why? Is this some kind of undercover investigation of our facility? Surely that can't be legal, and certainly not ethical.
I'd advise all staff to keep an eye on these patients - I'll be attaching their files and admissions paperwork.
