Chloe Tilley finds out why ticket resellers are having to face the music, hearing from music fans who paid hundreds of pounds to see their favourite performers. As the mystery of the suspected poisoning of a former Russian double agent and his daughter deepens, Chloe gets the inside track on relations with the Kremlin from the author of McMafia. Plus the programme gets a rare insight into what it is like to be in a coercive relationship, in which a person is emotionally, not just physically, abused by their partner.
