Black Earth Rising 9pm, BBC Two
Another stunning episode as Kate (Michaela Coel) returns to the UK from Rwanda, hoping to track down the item that is mysteriously missing from the old case file her murdered mother Eve compiled against the war criminal Patrice Ganimana. All she has to go on is its file number – but we have already seen the enigmatic padded envelope she’s looking for, being passed between several of the key players. Meanwhile, others are hunting for this crucial evidence too and are prepared to go to murderous lengths to get their hands on it. As the momentum begins to build, some long-buried, very disturbing complex truths are about to come out, including a revelation that leaves Kate questioning almost everything she ever thought she knew, about herself, friends and family.
