Murdoch Mysteries Wiki

Allen Clegg is an American agent first introduced in Season 4 of the Murdoch Mysteries, portrayed by Matthew Bennett.

Allen Clegg is a clever and danger arch-enemy of Detective Murdoch, Agent Meyers and Canada with a singular obsession with Manifest destiny – one country from the arctic circle to the Tropic of Cancer, the United States of America which means the take-over of Canada.

Appearances and Mentions

Confederate Treasure

  • Initially posing as a reporter named Carson Turner for the Toronto Gazette, Clegg approached Det. Murdoch under a fake alias for a comment on the remains of Mortimer Shanly, the first Minister of Militia Defense. However, he was more interested in knowing if perhaps he had found a letter from Sir John A. MacDonald on the body. When Murdoch declined to confirm or deny any claims to the case, Clegg left. Later, Murdoch is approached by Terrence Meyers, warning him that if he is approached by Clegg, to not say a word to him. Murdoch responds with telling him that he had already met him, albeit, under a fake alias. Meyers then informs Murdoch that his real name is "Allen Clegg", and that he is an American government agent.
  • Later on, Murdoch brings in Clegg for questioning following Burt Jacobsen's murder, with Jacobsen's wife being witness to Clegg rummaging to his belongings. Clegg drops all pretenses and states that Jacobsen was already dead when he arrived and he was searching for information on the Elvira May, a ship hired by Shanly to transport four strongboxes of gold bullion to a Confederate agent in St. Catherines. Murdoch became skeptical of Clegg's claims of the Canadian governments supporting the Confederates during the American Civil War, insisting that Canada was neutral during the conflict, but Clegg insists that Canada sought the schism of the American Union.
  • Clegg later caught a fishing boat carrying Murdoch, Meyers, Brackenreid and Crabtree scavenging the Elvira May's cargo. Clegg was expecting to find gold bars, only to find bricks instead, as a series of betrayals during the gold transfer resulted in bricks being put in their place. Clegg was then forced to let the Canadians go.

War on Terror

  • Clegg returns, having infiltrated the Toronto anarchist chapter when Emma Goldman arrives in the city, at the same time Murdoch and Meyers did too. He confirmed that Emma was not responsible for the bombing of Peter Milne's shop, which everyone assumes the anarchists committed, though he couldn't speak for the others. Meyers then inquired why he was in Canada without the authorization of the local government. Clegg said he didn't need permission, but after being reminded by Murdoch not to blow their cover, stated that the British Foreign Office, whose authority outranks the Canadian government, granted him permission.
  • Clegg influenced the young anarchist Pierce into committing a bombing in the square where Emma had given a speech, claiming it would impress her, though nobody got hurt. Emam deplored Pierce's actions, stating that it would not help their cause. Clegg, on the other hand, told Pierce that he did the right thing and that Emma was just being emotional.
  • Murdoch's cover was soon blown by Albert Wallace, a communist he had previously interviewed, forcing him to quickly declare Pierce under arrest. Clegg convinced Emma to let Murdoch go, stating that she was too important to the cause to be imprisoned.
  • After Constable George Crabtree determined that the bombing was caused by Milne's own landlord, Meyers personally escorted Clegg to the train station so he could accompany Emma back to the States. But before departing, they reveal that President McKinley's intended visit to Canada had been canceled by the State Department. Clegg promised that America will protect its own. Murdoch retorted that he felt that the Americans make their own problems, to which Clegg claimed was for God's country.

Murdoch Air

  • Clegg, acting under the alias Gleason, funds inventor James Pendrick to build his flying machine known as the Pendrick Arrow. But when the Canadian agents steal the aircraft in the name of national security, Clegg, in turn, stole it from them. But as he did not know how to make the Arrow turn, he kidnapped Pendrick, dislocating his recovering left shoulder to force him to cooperate, so he could learn how his flying machine works. When Murdoch learns of Clegg's involvement, he rescued Pendrick and the two made their way back to Canada via air. Clegg attempted to shoot them down but was unsuccessful.

The Spy Who Came Up to the Cold

24 Hours Til Doomsday

  • Clegg returns as the American ambassador to Canada. He is informed by the Prime Minister of Canada, Sir Wilfrid Laurier, that a rogue Canadian federal minister has threatened to fire a rocket projectile from Ontario to New York delivering some 200 tons of TNT in less than 24 hours. The Prime Minister wanted to inform the American government while Detective William Murdoch, the constabulary, and Canadian agent Terrence Meyers are working to find the rogue minister. Clegg appreciates the information, however, he ensures that if they failed and indeed lives are lost, the state of war will exist between the United States and Canada.
  • Following an investigation, it was revealed that Clegg actually met with the rogue minister to discuss a top secret defence plan involving a Canadian inventor James Pendrick. Unbeknownst to the inventor, the plan calls for mutually assured destruction if Canada and the United States were to be at war. However, Clegg in fact wanted to use the plan to incite war between the United States and Canada. To tie up loose ends, he also killed the rogue minister. At the end, he was arrested following the revocation of his diplomatic immunity. When asked by Meyers about his motivation, he answered that he did it for the safety of his country.

The Great White Moose

  • Clegg is obsessed that America had lost its opportunity in the War of 1812 to claim Canada as its own. Theodore Roosevelt says it's believed that he put a bomb on the hull of the USS Maine in Havanna Harbor, thus starting the Spanish-American War.

The Trial of Terrence Meyers

  • Officially declared dead by hanging on October 7, 1906, Allen Clegg has survived both the hanging and his own autopsy – unbeknownst to Detective Murdoch and Terrence Meyers.


  • The character Allen Clegg is named after the late MM writer Graham Clegg.
