Doctor Who scribe Gareth Roberts has, via Twitter, supplied the answer to a question that has puzzled Who fans and casual observers since the broadcast of his 2010 episode ‘The Lodger’: “What in the name of the Terrible Zodin is the deal with that creepy painting?!?’
Turns out it’s a portrait of Victorian music hall entertainer Dan Leno. But questions remain. Why is it there? Is it significant? Is that what Nick Cave would look like if he shaved off his new moustache?
