The highly anticipated return of "How to Get Away with Murder" won't disappoint as the official synopsis for episode 10, "Hello Raskolnikov," suggests a very interesting development.

"It's the day after Sam's murder and the students are called in to help Annalise find her missing husband, but just how much does Annalise know? And when a surprise visitor shows up in town, getting away with this murder might not be as easy as the students had hoped," the synopsis posted on Cartermatt.com read.

A few have started to speculate who the surprise visitor will be. As previous reports noted, 2 new cast members will be joining the show when "How to Get Away with Murder" season 1 resumes, and it is highly likely that one of them could be the person mentioned in the synopsis.

Emmy winner Cicely Tyson is reportedly joining the cast. Not much has been said about her role, but many are speculating that it will be a crucial part in the series. Some are even saying that she might play Annalise's mother. Fans will just have to wait and see.

Apart from Tyson, speculations arose that Marcia Gay Harden will also be joining the cast as what people believe to be Sam's ex-wife.

And what else can fans expect from the remaining 6 "How to Get Away with Murder" episodes?

"It's not gonna go how you expect. We pick up very soon after where Episode 9 ended. We are not doing flash-forwards, per se. We do play with time in different episodes. We felt for the final six that we want to put that device away because we had done it. A lot of the questions that we started with will be answered. How much do Bonnie and Frank know? In terms of what happens with Rebecca's trial, that will be resolved," showrunner Peter Nowalk shared.
