When Percival Jenkins, the master of a wealthy household, is found face down in his morning porridge, Murdoch is plunged into the complex and stratified world of the upstairs rich and downstairs poor. He comes to realize that any one of the household's many occupants had reason to murder the malevolent and lecherous old man: his hard-hearted wife, either of his two sons - the lazy, resentful elder and the dutiful, aggrieved younger (Craig Olejnik), the younger son's snubbed fiancée, or any of the downstairs staff - the butler (Simon Williams), the footmen, the matron, or any of the various put-upon maids. Meanwhile, Murdoch is surprised and delighted when Dr. Ogden shows up from Buffalo - she's a friend of the Jenkins' family. But, when Dr. Francis catches Dr. Ogden working in his morgue, Francis quits - much to the chagrin of Inspector Brackenreid. With Francis out of the picture, Murdoch suggests that Ogden stay in Toronto. But will she accept? Brackenreid puts aside his anger, realizing that Ogden's insight into the Jenkins' family can help Murdoch solve the murder.
