Murdoch Mysteries Wiki

Chief Constable Giles is a member of the Toronto Constabulary from at least 1881 up until his arrest in 1902, first introduced in Season 4 of Murdoch Mysteries, portrayed by Nigel Bennett.

Chief Constable Percival Giles is one of the antagonists of William Murdoch and even Inspector Thomas Brackenreid at times. They often disagree on crime solving methods.

Appearances and Mentions

The Murdoch Trap

What Lies Buried

  • It is revealed that Giles has a sordid past himself; he is a homosexual and was being blackmailed by the murder victim, Constable Finch (who was himself a murderer). Sadly, the man Giles was in love with, Peter Reid, turned out to be an accomplice of Finch, who had seduced Giles in order to let Finch take a compromising photograph of Giles. When Giles discovered he had been betrayed by his lover, he openly wept. Constable Hodge (who in those days had a friendship with Giles similar to Murdoch and Constable George Crabtree) accidentally killed Constable Finch while Finch (who was going to blackmail then-detective Giles) was trying to give on Giles' desk, the glass negative of the picture of Giles with Reed, by hitting him with the station mascot, an iron monkey statuette called "Nelly". Together, Giles and Hodge hid the body in the basement, which was just about to have a new concrete floor poured.
  • Constable Hodge is tried for manslaughter and Giles for obstruction of justice. According to Inspector Brackenreid, " he being an admitted homosexual who buried a body, not to mention he's a copper, will more than likely do more time than Hodge," which Murdoch finds unfair.
  • Part of the reason that Giles is so hell-bent on making Murdoch reveal the truth may stem from the damage that concealing his crime has done to his life and personal relationships.

Nolo Contendere

  • Percival Giles is in prison along with George. When a man who wanted information about George's ex-fiancee, Edna Brooks, gets stabbed, Giles helps George investigate after recognizing that he will not let it go. He advised George on the minds of the inmates, able to get a suspect for Murdoch by having the inmates bet on the most likely culprit.

Rigid Silence


  • Percival Giles was set to be released ago year as he had been a model prisoner.
  • He had picked the lock to the prison morgue, pried open a casket, and pulled the lid down by means of an improvised ratchet. The casket was delivered to the cemetery for burial, thus Giles escaped, scaring the gravedigger into a run for his life.


  • There has been several fictional Chief Constables (Chiefs of Police), when in actuality during Murdoch Mysteries time period, the Toronto Police Department was headed by Col. H.J. Grasett, who served as Toronto's Chief Constable for 34 years from 1886 to 1920 — a record that still stands.
