Many criminals made the mistake of underestimating Lieutenant Columbo, a homicide investigator with a crumpled trench-coat and a beat-up car, who certainly acted as an incompetent bumbler. 　　But he was so polite to every suspect, and he talked so much about his wife (who we never got to see on any episode, but who many believe later had her own show, starring Kate Mulgrew, later of Star Trek: Voyager fame) that he lulled even the shrewdest murderer into a false sense of security. 　　And although the audience had witnessed the murder in the beginning of each episode, it was still a surprise to see what mistakes the killers had made during the seemingly perfect murder.

Season five of Murdoch Mysteries opens in unfamiliar territory, as Detective William Murdoch (Yannick Bisson) leaves Toronto to try his luck while the Klondike Gold Rush in the Yukon winds down. Suspended for interfering in an investigation, on the run for surreptitiously freeing a murderer to make amends, and nursing a broken heart after Dr. Ogden's marriage to another man, he tries to escape his past, and his passion for detective work. Back in the city, newly promoted Chief Constable Giles (Nigel Bennett) makes it clear to Inspector Thomas Brackenreid (Thomas Craig), that he'll be keeping a very close eye on police matters. Meanwhile, Murdoch's beloved former associate, Dr. Julia Ogden (Hélène Joy), is now working alongside Acting Detective George Crabtree (Jonny Harris) and Dr. Emily Grace (Georgina Reilly), a feisty young protégé. In the remote north, Murdoch is pleased to discover that his fledgling prospecting career may garner great success, a small comfort after Julia's marriage to another man. But as he tries to rebuild his life, he finds himself drawn into the case of Mrs. Elizabeth Bryant (Jill Halfpenny), an innkeeper charged with murder. The plot thickens when writer Jack London (Aaron Ashmore) lends his insights, and Murdoch soon realizes that while he had hoped to leave his shattered heart and tattered career back in Toronto, his days as a detective are not behind him.

On a sunny beach day, a sneaky thief makes off with every drop of milk meant for a group of baby elephant seals. Luckily, Sam and Kit are on the case.
