Ordeal by Innocence

Another British import, this one a darkly delectable three-part adaptation of an Agatha Christie whodunit. When philanthropist Rachel Argyll is fatally bludgeoned with a decanter, suspicion falls on the bad-seed son among her now grown adopted children. But Rachel turns out to have been a monster who’d given almost every member of the household a reason to want her dead, as becomes clear a year after the crime. With Bill Nighy and Anna Chancellor.
