After being on hiatus for weeks, "Bones" season 11 finally returns next week with its 21^st episode titled "The Jewel in the Crown."

The upcoming episode features a mysterious murder case involving a woman whose body was discovered with a diamond embedded onto her jaw.

In the episode, the team tries to discover why the murderer had to implant a diamond onto the woman's jaw. The team finds out through the preliminary investigation that the victim comes from a noble family. It also turns out that the primary suspect in her murder is her husband.

Meanwhile, "The Jewel in the Crown" also follows some of the characters as they deal with some personal issues.

The description of the episode published on Spoiler TV reads, "The team investigates a body found at a glass recycling plant with a diamond lodged in its jaw. French Inspector Rousseau approaches the team with an accusation against the Marquis De Chaussin, who is revealed to be the victim's husband and lives in Virginia. Meanwhile, Booth discovers he suffers from a temporary eye illness, and Hodgins thinks he's being followed by a ghost."

One photo posted on the site shows FBI Agent Seeley Booth wearing eye glasses after learning about his eye illness. Another one reveals Marquis de Chaussin nudging a gun at Inspector Rousseau.

Aside from the investigation, another interesting story to watch out for in episode 21 is that of Dr. Jack Hodgins, who feels that he is being haunted by a ghost.

"Bones" season 11, episode 21 airs on July 14 on Fox.
