Comedian Mark Steel's hilarious and heartbreaking exploration of his own adoption.

Growing up in humdrum Swanley in Kent with loving parents, Mark Steel had never been bothered about being an adopted child. But in later life, established as a successful comedian and writer, he decided to search for his biological parents.

What he uncovered was a story so strange, a cast of characters so eccentric and far-fetched that he was transported to social and cultural divides that spanned half the world. His mother had at first refused to have Mark adopted, while his father later went on to become a key player in Mayfair's Clermont gambling club and reached the pinnacle of high society. What happened when Mark finally contacted both his parents is as moving as it was entirely unexpected.

As well as his own story, told in his uniquely endearing and hilarious voice, Mark delves into the more serious aspects of adoption, single motherhood and the brutality of the social attitudes of the time. He surveys the testimony of mothers and those adopted and tries to find reasons for his own mother's crucial and agonising decision. Who Do I Think I Am is one of the funniest, most heart-breaking stories you'll ever encounter.
