Television’s current biggest “whodunit” will officially conclude on Tuesday night when “Scream Queens” airs its anticipated -- not to mention bloody -- Season 1 finale. And while we’re teary-eyed over the thought of bidding our favorite, new Fox TV series farewell, we’re also extremely excited to finally find out who the Red Devil killer of Wallace University is.

In an interview with E! Online, Ryan Murphy, co-creator of the side-splitting and throat-cutting dramedy, revealed that the murderous character wouldn’t be unveiled until the very last episode of the show. And according to reports, the unmasking of the killer won’t just shock audiences, but it will also take the cast of “Scream Queens” by surprise!

“[The cast has] been blackmailing me, bribing me, writing me,” he elaborated to Variety, noting they’ve all been dying to find out who the killer is. (And yes, that pun is totally intended.) “They all have their theories about who they think it is, and none of them have been right, which makes me very happy. I love their enthusiasm, because I feel, hopefully, that the audience will share it.” And, boy, do we ever!

Week after week we’ve been speculating who could be behind all the gruesome deaths from the demise of deaf Taylor Swift (Whitney Meyer) to the deep-frying of Gigi’s (Nasim Pedrad) head. And although it seems like the killer could just be about any character introduced over the course of the freshman installment, we still have our suspicions of who might be hiding under that red, devil mask. Check them out below:

1. Chanel’s Minions No. 3 and No. 5 (Billie Lourd and Abigal Breslin)

In the pilot episode, Melanie Dorkus (Brianne Howey), the former president of Kappa Tau, was severely burned after her self-tanner was tampered with. Originally, Dean Munsch (Jamie Lee Curtis) suspected Chanel (Emma Roberts) of the heinous crime, which involved replacing the orangey liquid with chemicals. The dean then later accused Grace (Skyler Samuels), but we, however, think Chanel’s ride-or-die minions might have meddled with Melanie’s tanner after she uninvited their soon-to-be fearless leader on her Spring Break trip. (No one puts Chanel in the corner!)

2. Chanel No. 5 (Abigal Breslin)

Or maybe Chanel No. 5 was acting alone. When Boone (Nick Jonas) revealed he was joining the KKT is episode 1, Chanel No. 5 had a meltdown. Is that because Boone -- who was confirmed to be one of the Red Devil killers -- is actually Chanel No. 5’s brother?

It was already confirmed that Boone was just one of the bathtub babies born that night at the sorority in 1995. The other child born was a girl -- who has since been working with Boone and Gigi to seek vengeance for the events of that fateful night. Perhaps Chanel No. 5 didn’t want her careless brother ruining her two-decade mission of taking down Kappa by joining the sorority.

Also, Pete (Diego Boneta) previously told Chad (Glen Powell) that Boone was his inside source of getting scoop on KKT -- was that because Boone himself had a source: Chanel No. 5? (#Cahoots!)

3. Grace

Grace has been an oddly suspicious character since the very beginning of “Scream Queens,” which is why the newsboy cap-sporting sorority sister has made our list of potential killers. Not only was her mother one of the Kappa’s involved in the bathtub baby scandal but it was also revealed her father (Oliver Hudson) is the biological father of Boone, which makes Grace the biological sister of the late Dickie Dollar Scholar -- but is she his killer sister?

Although we have our ideas of who the murderer might be, it seems that anyone could fit the blood-soaked mold. However, Murphy claimed that he made it "very clear" who the knife-wielding character was in the very first episode of the series. “When the killer’s unmasked at the end, you’ll be able to go and be like, ‘Oh, yeah’ and link all that stuff together,” he told Variety.
