Tracks is a British thriller-mystery fiction podcast created and written by Matthew Broughton, and primarily directed and produced by James Robinson.
The series follows the investigations of Dr. Helen Ash, a primary care physician whose life is changed when she witnesses the crash of a plane on which her estranged father was a passenger.
Romola Garai, Hattie Morahan and Olivia Poulet all provide the voice of Helen over the course of the series, alongside Jonathan Forbes as Freddy, her long-lost friend who helps her in her investigations.
The second series, Strata, is a prequel set in 1980 in the wilds of Snowdonia, and follows Rachel Turner, a woman on a desperate search for her four-year-old son Joel, who went missing in an earthquake while she was looking for fossils; while looking for him, they stumble upon events relating to a strange pregnancy.
The fifth and final series, Abyss, follows Helen, now suffering from terminal cancer, investigating the mysterious sinking of a boat.
