Winslet is in stunning form as the put-upon but never downtrodden cop and matriarch. ... This is high-end telly at its best, packed with intrigue, suspicion, horror and reluctant heroics.

Sometimes the conclusions to the crimes can feel secondary to the driving personal stories. But when the balance works, such as with the siege story from the third episode, it’s a really strong combination – and makes for a fine addition to the detective genre.
