Homeland (Channel 4, 9pm)
It’s official – Homeland is the best American drama currently on our screens.

But after the programme swept the board at the Emmys last month expectations are even higher for this second run.

Meanwhile Brody, now a congressman, is struggling to deal with the pressures of public office.

While Banks moves to the capital to find him, new sidekick DI Helen Morton is called in when a young woman’s body is found in a car.
But why does the corpse have Banks’ name and address written on a piece of paper in her pocket...
