Yanks In The UK Brennan and Booth travel from D.C. to London for Brennan to guest-lecture at Oxford University and for Booth to speak at Scotland Yard. They are asked by local officials to lend their expertise to a high-profile murder investigation involving a young British heiress and are paired up with their respective British counterparts, Dr. Ian Wexler and Inspector Cate Pritchard. The duos venture through London to investigate the puzzling murder of the young and glamorous heiress, whose father is a wealthy American businessman. Meanwhile, back in D.C., the Jeffersonian team lends its expertise to the Brits' case, but they are thrown for a loop by the unexpected return of Angela's long-estranged husband who must consent to a divorce before she can marry Hodgins. When a member of the U.K.'s own investigative team is murdered, Brennan and Booth's personal connection to the case strengthens their resolve to help solve the mystery surrounding the death as they search for the London killer.
Man In The Outhouse When a partially decomposed body is found in an outhouse and identified as the host of a popular reality television show, "Busted by Bill," which catches infidelity in the act, Brennan and Booth must identify the killer from of a large pool of suspects, including many who were humiliated on the victim's show. As the team searches for key forensic evidence with the help of Brennan's overachieving grad student, Sweets and Bones watch episodes of "Busted by Bill" to search for suspects who fit a revenge killer's profile. Meanwhile, Booth tries to understand Brennan's romantic life when he learns she is juggling two relationships.
The Finger In The Nest When Booth's son Parker finds a severed corpse finger in a bird's nest while playing with Booth, the team launches an investigation to find the rest of the body. They locate the corpse in Jefferson Memorial Park, and it soon becomes clear that the death was no accident. With the help of a new middle-aged grad student in the lab, the team identifies the victim as a local veterinarian whose penchant for gambling brings a number of suspects into the picture. When the victim's fatal injuries are found to be from a dog, the team uncovers an illegal dog fighting ring and enlists the help of Cesar Millan to help them connect the forensic canine evidence with the killer dog and its owner. Meanwhile, Booth asks Sweets to psychoanalyze his son who he thinks has been traumatized from finding the finger, and Sweets confronts Hodgins about his attitude in the lab.
The Perfect Pieces In The Purple Pond When a shocked teenager finds a dismembered body laying in pieces in a strange purple pool of water, Brennan and Booth come to the scene only to find the victim's head is missing. With help from Brennan's newest grad student, Wendell, the team discovers the body is that of Jared Addison, a 25-year-old science fiction writer who suffers from OCD and a crippling fear of germs. With Sweets' psychological insight into Jared's perfectly regimented world, Booth and Brennan track down a number of suspects including Jared's psychologist, his much older girlfriend and his science-fiction book publisher, all of whom have good reason to want Jared out of their lives. However, without the victim's head, the team struggles to find enough evidence to locate a killer that is, until they receive insight from Zack, who studies the case from afar at his psychiatric facility with case information provided to him by Hodgins. Meanwhile, Brennan scolds Booth for not letting her ever fend for herself.
The Crank In The Shaft When the remains of a much-disliked company office manager are found in a building elevator shaft, Booth and Brennan must find out which one of the employees had reason to murder the victim. From a recently-fired employee to the victim's own boss, the team realizes this office manager had more than their share of complaints to file. Meanwhile, Brennan's bleak and morbidly realistic grad student lends his insight to the case, and Hodgins and Angela try to navigate their post break-up relationship.
The He In The She When skeletal remains are found in the Chesapeake Bay, Brennan and Booth are on the case to investigate. With only the upper torso of the victim intact, the team has little to work from besides the remnants of the victim's breast implants. Brennan and Booth are led to a small church community in Maryland where the victim was a pastor, but they have no record of her existence prior to moving to the small town five years prior. When the victim's lower half is discovered, the team realizes their initial assumptions about the victim may not be correct. As Sweets lends insight to the victim's psychological state and Brennan's latest grad student adds his own offbeat observations, the team must decipher who would have wanted her dead. From possible love interests to her family to the parishioners at the church where she was a pastor, the anatomy of the case is very misleading.
The Skull In The Sculpture When the smashed remains of a well known artist are found in an impounded junkyard car, Booth and Brennan are on the case to find out if foul play is to blame for his death. With suspects ranging from the artist's rival to his own assistant, the team must race against the clock to find evidence of murder before the car is relinquished and put on exhibit as the sculptor's ultimate display of self-sacrifice for the sake of his art. Meanwhile, Angela's ex-girlfriend Roxie, who worked with the artist, becomes a suspect in the case, and Angela and the team must find out who delivered the final stroke in his artfully crafted death.
The Con Man In The Meth Lab Booth and Brennan investigate the scene where a body was uncovered during a botched practice police raid. The team identifies the body as a struggling inventor's father who had recently reunited with his son. But when a second body surfaces, the team is led on a trail of deception to find out who was the actual con-man in the inventor's life. Clark Edison returns to the lab, and he and Hodgins work on piecing together blueprints from one of the inventor's potentially valuable inventions. Meanwhile, Booth's younger brother Jared moves to D.C. to take a job at the Pentagon, and Brennan, smitten with Jared, agrees to go on a date with him to a White House function. Her date with Jared leads her to learn information about Booth's past and give her a far greater understanding into her partner's motives.
The Passenger In The Oven Booth and Brennan are en route to China where Brennan has been summoned to help identify pre-historic anthropological remains with Booth in tow to watch over her highly sensitive equipment. Their restful flight is disrupted when a flight attendant discovers a fully cooked human body in the plane's industrial microwave. Booth and Brennan connect online with the team back in the U.S. using Brennan's high-tech equipment, as well as odds-and-ends gadgets from the airline passengers, to send evidence back to the Jeffersonian for processing. When they identify the victim as a travel writer working on a controversial story about airline pilots, Booth and Brennan race against the clock to solve the murder before the plane lands in China and they lose their jurisdiction over the case. Meanwhile back in the states, Angela and Roxie's relationship progresses as Hodgins tries to move on.
The Bone That Blew When a skull and various skeletal remains are found in a tree in a nationally protected wooded preserve, Brennan and Booth are on the case to investigate. Back at the Jeffersonian, Brennan learns of her estranged father's new position as a teacher, a prospect she is less than happy to learn about considering his recent acquittal for murder. In a lucky break, the victim's bones are identified in a government database as those of an ex-Marine who has been off-the grid for nearly three years. With no records of his whereabouts from the past three years, the team turns to the internet for answers. The investigation eventually leads Brennan and Booth to an ultra-elite private school and a group of rich and powerful families, one of whom the ex-Marine had worked for as a "manny." As the investigation continues, the team finds Brennan's father to be an unlikely asset to the case, but Brennan has mixed feelings about her father's involvement. Brennan and Booth's investigation delves deep into the world of lies and deception of the ultra privileged families.
The Double Trouble In The Panhandle Booth and Brennan investigate the remains of conjoined twins found in a shallow grave in a remote desert area on the Texas-Oklahoma border. Back at the lab, the team determines the skeletal remains to be those of Jenny and Julie, who were jugglers in a traveling circus. Knowing there is no way the circus folk will talk to anyone outside their tight-knit clan, Brennan and Booth must infiltrate the circus community in order to find out more information about the twins' deaths. Honing Booth's Ranger knife-throwing skills, the duo goes undercover as knife-throwing act "Buck and Wanda Moosejaw." As they encounter a variety of suspects among the colorful circus crowd, including ringmaster Henry Simon, a rather raucous clan of clowns and a tempestuous strong man who may have been romantically involved with one of the twins, Booth and Brennan find the circus experience to be quite the spectacle.
