"Rosewood" is all new Wednesday night, when the unstoppable man of the hour will solve a murder case involving a doctor and multiple victims.

"A doctor is a murder suspect, but Rosewood (Morris Chestnut) and Villa (Jaina Lee Ortiz) have limited evidence to prove he killed two of his patients," the show's description reads on TVGuide. "Meanwhile, Villa clashes with Hornstock (Domenick Lombardozzi) over the pursuit of a case; and Rosewood receives an anonymous letter that could have life-altering implications."

What will Rosewood find out in Season 1 Episode 4? The pathologist has been following a case since the last episode, in which he has been defending an ex-con whom he believes to be innocent. Will the referenced letter have something to do with that case?

In the episode, titled "Vandals and Vitamins," viewers should also expect to see Villa and Rosewood getting even closer together. As the season goes on, the widow seems to be letting her guard down a little bit.

In the last episode, "Have-Nots and Hematomas," Villa turned to Rosewood when she was feeling lonely. But he was in bed with his lover Kat (Nicole Ari Parker). There could be a love triangle brewing between the three of them.

However, Taye Diggs has recently been cast on "Rosewood" as Dr. Mike Boyce, a possible love interest for Villa. Diggs will have a recurring role as a Miami-based infectious disease specialist, who is also Rosewood's best friend.

Rosewood has had an eye for the hot detective since the pilot episode. Meanwhile, Villa has already sent signs that she is into Rosewood, but she is afraid of getting hurt again. Will Rosewood let his best friend know how he feels? Or does that trio present another possible love triangle?

The Fox series premiered on Sept. 23 and is already gaining popularity. The "Think Like a Man" actor stars in the show as a private pathologist named Beaumont Rosewood, who helps the Miami police department solve its toughest cases.

Chestnut and Diggs also starred together in "The Best Man" and "The Best Man Holiday."

Tune into Fox at 8 p.m. on Wednesdays to catch all new episodes of "Rosewood."
