"Nolo Contendere" is the first episode of ninth season of the Murdoch Mysteries and the one hundred-fifteenth episode of the series. It first aired on October 5, 2015.


George Crabtree is in prison for the murder of Archibald Brooks. When an inmate claiming to know something about Edna Brooks is killed, Crabtree worries that she may be in danger. Murdoch looks into a break-in at her house that may have been perpetrated by Edna herself.

In the Season 9 premiere, as former Constable George Crabtree serves hard time for the murder of Edna Brooks’ abusive husband, Murdoch and Higgins visit Edna’s old apartment, the site of a recent burglary. Murdoch is convinced that something of significance has changed and takes a series of photographs to compare them with the ones taken earlier at the crime scene.

Back at Don Jail, the murder of a fellow inmate named Foster who had warned Crabtree that people were looking for Edna prompts George to reach out to Murdoch for the first time. Crabtree shares his findings: Foster was in the same regiment as Archibald Brooks, they share a regimental tattoo and he was asking Edna's whereabouts. Foster’s murder may have something to do with Archibald Brooks. Though Edna may be in danger, George still doesn’t reveal her whereabouts to Murdoch. Murdoch assures George that he will look into the matter. The search for cues to how the burglary and the prison murder are connected to Brooks, providing the critical evidence to exonerate George, begins.

From within Don Jail, Crabtree and former Chief Constable Giles work together on a simple, yet clever, scheme to get fellow inmates’ to play against one another to find out who killed Foster. The trick is to measure the deviation between the expected and the empirical results to find an anomaly, which turns out to be Pearson– who was hired to kill Foster.

Murdoch, Dr. Ogden and Inspector Brackenreid work to untie a knot of evidence, old and new, involving a raw diamond, assumed identities, bicycle grease, Roquefort cheese, a bloody scarf, and murderous army buddies, while prime suspects remain elusive or dead.

Finally, George admits to Murdoch that he did not kill Archibald Brooks and where Edna is hiding. Both thinking that the other had killed Brooks, they kept their silence. Reunited with George, Edna tells him that Simon ran away thinking she had killed his father. Since George had wiped all finger marks that could have proven them both innocent, Murdoch re-examines all the evidences to determine the identity of the real killer.
