When CeCe was revealed to be A, we got a lot of answers then, but not all. The biggest mystery still remained, who killed Mrs. D and why the liars have been tortured since the beginning. I. Marlene King did promise to reveal that at the end. Next week we will finally find out who killed Mrs. D!

Mrs. D’s death was one of the biggest shocks in the entire series and it’s still a mystery to this day. I think at the time we all just assumed A was behind it, but maybe not. I get nervous when big reveals happen because it needs to be big. But it also needs to make sense. Not long now until we finally get our answer.

Take a look at the promo and take your best guess at who killed Mrs. D:
