This Friday's all-new episode of "Grimm" will be quite intense as Nick, Hank and Wu track down a ghost-like beast and Juliette struggles to hide her transformation into a Hexenbiest.

In the upcoming episode, entitled "Death Do Us," Nick, Hank and Wu will investigate a spooky homicide that locals believe occurred in a haunted house.

A sneak peak video clip shows the officers inspecting the murder scene and the body of the victim, who is a ghost hunter that looks like he was struck by lightning.

In another teaser video, the three cops are watching a video clip that the victim recorded right before he was murdered by a mysterious creature.

The promo video also hints that Nick may realize that Juliette is a Hexenbiest.

In addition, actress Garcelle Beauvais will guest star as a woman from Captain Renard's past.

According to TVLine, Nico Evers-Swindell, the actor best known for his role as Prince William in the "William & Kate" TV movie, will make a guest appearance as Prince Kenneth in two upcoming episodes of "Grimm."

Evers-Swindell's character, who is described as handsome, ruthless and commanding, is sent to Portland by the King in a mission to recover Adalind's daughter.

Dread Central reports that the official synopsis for "Death Do Us Part" reads as follows:

"Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) are finally off on their honeymoon, but that doesn't mean trouble isn't stirring in Portland. Nick (David Giuntoli) and Hank (Russell Hornsby) are called to a shocking homicide at an abandoned residence many Portland locals think is haunted; even the survivors swear a ghost committed the murder.

"Meanwhile, on the heels of Juliette's (Bitsie Tulloch) startling revelation, Captain Renard (Sasha Roiz) seeks the help of a mystical woman (guest star Garcelle Beauvais; "Franklin & Bash," "The Mentalist") from his past. Reggie Lee also stars."

Season 4, Episode 11 of "Grimm," "Death Do Us," premieres on NBC on Friday, Jan. 30, at 9 p.m. ET.
