Episode 37 of "Bones"
s02e15 Bodies In The Book

Brennans latest murder-mystery is an immediate best-seller. Enjoying her success and her newfound love with Agent Sullivan (Sully), Brennan prepares to hit the publicity circuit to promote the novel. However, when she and Booth investigate a murder in the marina, they notice striking similarities between the case and one of the fictional murders in Brennans book. A shaken Brennan grows impatient as her team suggests the murder was not an eerie coincidence, but the work of a copycat killer mimicking the murders in her novel. If this were true, the murder in the marina would be only the first of three gruesome killings, and the Jeffersonian buzzes with talk of what might happen next. Tensions build as Sully and Booth vie to protect Brennan and investigate possible suspects, including an overly obsessive fan who once stalked her. When a second murder is committed exactly like one of Brennans fictional killings, she is overwhelmed by the possibility of playing a role in the loss of innocent lives. With a potential third murder on the horizon, the team races to identify the copycat killer before the deadly final chapter unfolds.
