Children's author Robert Muchamore visited Norwich this afternoon to sign copies of his latest book.

The author of the bestselling CHERUB series stopped off at the book department of Jarrolds, in London Street, to sign copies of his latest book; Henderson's Boys: One Shot Kill.

The book - the 39-year-old's 20th book, which was released on Saturday - is the sixth adventure in the Henderson's Boys series.

The book is based in 1943 and precludes the CHERUB series, following British secret agent Charles Henderson during World War Two - which leads to the creation of Charles Henderson's espionage research unit B (CHERUB).

The books have led to Londoner Mr Muchamore winning awards such as the Red House Children's Book Award for Older Readers in 2005 and the Independent Booksellers' Prize 2008.
