It's a good read. 30 pages of 250 are devoted to his one year on Doctor Who; 80 to his eight years on Blue Peter. That's still less than half of the book, and he makes a good set of anecdotes out of the indignities of the life of an actor, and his subsequent shift to directing (I wished he'd said a bit more about that) and presenting various TV programmes about subjects such as dogs and darts. He also seems to have settled down into a long-lasting second marriage. (Not mentioned in the book, but his Gilly Fraser, his first wife, also appeared in Doctor Who as Ann Davidson, the possessed air stewardess in The Faceless Ones.) The most moving section is where he writes about Petra, the Blue Peter dog who he looked after for much of her long life; she was a rather difficult dog, but she taught him a lot.
The book also provided me with a moment of unexpected enlightenment about Dire Straits. I'm sure many of you are familiar with their song Tunnel of Love. I had personally always been mystified by the lines "Girl it looks so pretty to me / Like it always did / Like the Spanish City to me / When we were kids." It turns out (and here those of you familiar with northeast England will be giving me serious side-eye) that the Spanish City was a famous funfair, close to the railway stations of Cullercoats and Whitley Bay, just north of the mouth of the River Tyne, where the young Peter Purves was taken by his grandparents while visiting from Blackpool, and where the young Mark Knopfler acquired a taste for rock and roll a decade or so later.
One shouldn't expect a lot from celebrity memoirs, but this one is reasonably shot through with humanity and a certain degree of humility. Acting is a fragile career, and Doctor Who and Blue Peter, Purves' high points, both came pretty early. He's had a lot of time to reflect, sometimes through force of circumstances, and this book that doesn't promise much does deliver a bit more.
