The on-screen programme guide (Virgin Media) which I just checked on our tv has a 10 minute programme called "Philip Hoare's Guide to Whales" scheduled for 20:50 and that's what is on the BBC Four listings on the website too, so it looks as though it will start at 21:00 as usual. Anyone not willing to trust this information would be advised to set to record from 20:50 to 22:30 just in case, though you might find a soothing documentary about whales to watch for 10 minutes before the mayhem, murders, explosions and intra-force romances kick off in southern Sweden.
