8:30pm – Friday, October 29 on ABC1
Kirsten Ross, a young mother, has been abducted.
Luther realises that this is the work of Lucien Burgess, a collector and writer on the occult who was suspected of the murder of another woman, Grace Allen, 10 years previously; but Burgess was never charged.
On a deadline to find the young mother before it’s too late, Luther and Ripley work into the night to piece together clues and link Burgess to another murder committed 20 years earlier.
Luther and Ripley’s investigation leads them to the canal, where they find Burgess’s narrow boat.
Meanwhile, Luther’s ex-wife’s partner Mark is beaten up. With relations strained between ex- Zoe and Luther, Mark automatically assumes that Luther is responsible and reports the assault. But the culprit is not as suspected, and a further twist emerges as Luther receives a recording of the assault from an unknown source.
