Murdoch Mysteries: Season 5, Episode 4

5 - 4: War on Terror

Constables Crabtree and Higgins are caught up in a shop explosion and Murdoch soon discovers the remains of a homemade bomb. When the shopkeeper tries to demand restitution from the police for his losses, Brackenreid is furious, as Higgins has been badly hurt. It is then discovered that the businessman is extremely unpopular with his business neighbours, including one in particular who harbours a deep grudge against him. However, further developments lead the police to believe that they themselves may have been the intended targets. The arrival on the scene of a high level government official then points to evidence that the incident may be connected to the US president, and suspects include the famous anarchist Emma Goldman.
