Muriel McKay’s kidnapper – who calls himself M3 – has stopped calling, and the McKay family are desperate. They use Alick’s media contacts to keep the story at the forefront of the tabloid press, placing rumours designed to make the kidnappers panic, even getting in touch with a clairvoyant via a family friend.

But what the press don’t know is that Muriel McKay was kidnapped by mistake. M3’s real target, he says, was Rupert Murdoch’s wife.
