Last night was the grand reveal of the Twelfth Doctor on BBC1 - and it's Peter Capaldi, who was a wonderful Angel Islington on the original Neverwhere TV series. He was also the civil servant in Torchwood: Children of Earth, and the Roman dad in Fires of Pompeii - which is quite a range even without considering The Thick of It (which I haven't seen).
I'm sure he'll do very well.
Meanwhile, I finally realised that the dark blue silk waistcoat I picked up at a charity shop is Tardis blue - so what it really needs is a St John's Ambulance brigade badge to pin on it. I found just the thing on ebay, from a seller in the Netherlands, and it looks absolutely perfect!
