An unlikely friendship with a ginger tomcat has led to a book deal and a new way of life for a former homeless north London busker.

James Bowen's A Streetcat Named Bob details his near-10 years of living rough on the streets and busking in Covent Garden with his four-legged companion.

Now living in Tottenham, Mr Bowen and Bob have attended the first signing session for his book, where all 400 copies of the initial print run have sold out.
