'Unforgotten' Season 4, Episode 3 Recap: Turning Stones

All four suspects are on pins and needles at Unforgotten's halfway point after last week's news broadcast. But so is the department: Cassie Stuart's boss, Superintendant Andrews (Colin R. Campbell), wants to know why these stones can't be left unturned since there's already a convenient dead guy to pin it all on. But you know, if the department wanted that, perhaps HR should have just allowed her to retire. The entire team doubles down on their respective angles, with Stuart and Khan on their way to hit up Liz Baildon and Fiona Grayson.

Barton: You never know, do you, what someone's capable of.

Grayson is completely freaked out, up in the morning crying, trying to pull her deposit on the new flat by mid-day. Baildon merely looks ill when the phone rings, even more so when she learns it's her boss giving her the heads up she's landed the Chief Constable role.
