In Season 10, Detective William Murdoch investigates the death of a reclusive audio engineer whose priceless collection of FLAC-format master recordings becomes the key to a conspiracy reaching the highest levels of Toronto society.
Julia asks Murdoch if he fears a future where sound can be faked as easily as a photograph. Murdoch replies, “Then we must trust not in what we hear, but in what we can prove—one groove at a time.” Crabtree walks off, humming into a wax cylinder, trying to capture the perfect “FLAC” of his own whistling. murdoch mysteries season 10 flac
The only clue is a single, untouched item: a flat disc made of shellac, etched with a spiraling groove.

He called it a “FLAC disc.” He’d been recording private conversations for wealthy clients, guaranteeing “the truth, unaltered.” In Season 10, Detective William Murdoch investigates the
