Cardinal is now available to stream on U in the UK, giving viewers all four series of the Canadian detective drama in one place. For fans of Broadchurch, it is an easy next watch: another slow-burn mystery built around a troubled detective and a case that will not let go.

The series follows Detective John Cardinal, who returns to the homicide unit after being demoted for becoming obsessed with a missing-girl case. When the teenager’s body is found down a mine, he is pulled back into murder work and paired with Detective Lise Delorme, who is also looking into him as part of a federal police corruption probe. Cardinal is suspected of working with a drug dealer, which gives the partnership an edge from the start.

That setup is part of what has kept the drama moving across four series. Adapted from Giles Blunt’s John Cardinal Crime Series novels, it is set in the small Northern Ontario town of Algonquin Bay and keeps widening its casebook as it goes. Later episodes bring a woman found with a bullet in her head and no memory of who she is, a complex double murder and a bizarre missing-persons case, all while Cardinal and Delorme keep circling the same uneasy questions.

For viewers deciding what to watch next, the pitch is straightforward. A programming chief described the series as a finely nuanced, atmospheric thriller that is completely gripping from beginning to end, and said Broadchurch fans will no doubt enjoy it for its complex characters, slow-burn mysteries and the detective duo at its centre. The bigger draw now is convenience: all four series can be streamed at once on U, with no new release schedule or follow-up plan announced.
