"From Murdoch to Eternity" is the fourteenth episode of the tenth season of the Murdoch Mysteries and the one hundred forty-sixth of the series. It first aired on February 13, 2017.


Murdoch creates a mysterious tonic that restores youthful vitality, but his pursuit of a partnership alarms Crabtree.

Detective Murdoch gives a presentation with a tribute to the late James Pendrick and announcing the inventor's nearly perfected potion - a revolutionary break-through that Murdoch himself has unlocked– Pendrimine. The promise of eternal youth in just one dose, with the proof in the shocking appearance of Inspector Thomas Brackenreid, but is it worth going to jail for? Or is it a ruse?

When diplomats from all over the world are interested in bidding for the Pendrimine formula, Murdoch may just find someone with sufficient capital to make enough for the entire world, but Canadian Intelligence agent Tanner is sent by the Prime Minister to obtain the formula on behalf of the federal government of Canada. Murdoch welcomes him to make a bid for it – starting at one hundred million dollars – "for a formula that will change life as we know." But Canada's offer is zero. Agent Tanner suggests Murdoch do the right thing; it would be a shame "if you were to be convicted of... treason." A hanging offense.

Suspicious of Murdoch's intention and uncharacteristic behaviour, Crabtree's own investigation leads him to inadvertently let James Pendrick's killer escape while uncovering the Pendrimine ruse. The ruse is simple, pretend that Murdoch's key "additive" and that the stolen formula actually works. Pendrimine as a whole would be valuable to everyone but the additive alone would only be worth something to the person who'd stolen the formula and killed Pendrick.
