Full-time luddite, John 'Ludwig' Taylor, assumes the identity of his missing twin brother in a bid to track him down and bring him home. However, filling the shoes of your identical twin is one thing - when your twin also happens to be a successful DCI leading Cambridge's busy inner-city major crimes team the stakes are much higher.
