London: Dressed in his red hat and blue duffle coat, Paddington Bear heads to London's St Paul's Cathedral in late creator Michael Bond's last book about the much-loved children's character.

The author was working on Paddington at St Paul's before his death last year at the age of 91.

In his latest adventure, the marmalade-loving bear, prone to all sorts of mishaps, visits the famed London site where, in a commotion, he is mistaken for a member of the choir.

"Paddington was always part of our lives, he was never far from his mind," Karen Jankel, Bond's daughter said of her father on Wednesday at an event at St Paul's to promote the book's Thursday release.

"I think when he came here, the idea of Paddington coming here sort of came to him and that ... inspired him."
