As the writer himself acknowledges at the end, he's augmented this a little but most of it is already the stuff you couldn't make up! He buys a new home in a well-to-do street in London's Camden only to find the area "blighted" by a curmudgeonly and smelly old woman who lives out of her rusting old van. When it comes time for her to move on, she ends up parked outside his new home and prevails upon him to use his facilities. That's just the start of a friendship that develops over fifteen years in which Bennett (Alex Jennings) discovers that this is an interesting and talented lady. It's quite easy to make judgements about her (Dame Maggie Smith) in the beginning, but as we go along we begin to realise that her supposed temporary existence has come to suit her perfectly, even if it does irritate her more respectable neighbours. The story of their relationship is told by the renowned playwright talking to himself much of the time and this series of conversations questions not just her existence but his own too. His narration is witty, perceptive and entertainingly expressive and the whole thing is enigmatically topped off by an actor who seems to be having an whale of a time portraying a woman of true character. It is a little bit long and does rather run out of steam towards the inevitable conclusion, but it does make you stop and think a little about homelessness, ageing and just how satisfying life can (or cannot) be.
