Paddington, the bear from Peru, will be arrested and interrogated over his immigration status in a book marking his 50th birthday.
It is almost 30 years since Michael Bond wrote the last book
Paddington Here and Now, due to be published in June 2008, is set around the bear's home at 32 Windsor Gardens, Notting Hill, west London.
It will mark the 50th anniversary of his debut in A Bear Called Paddington.
Author Michael Bond, 83, who lives in London, said while the world had changed Paddington remained the same.
This will be the first book about the marmalade-loving bear to be published since Paddington Takes the Test came out in 1979.
Mr Bond, who lives near Paddington in central London, said, "Although the world has changed considerably over the past 30 years, he remains exactly the same - eternally optimistic and ever open to what life has to offer.
"It makes writing the stories a pleasure."
In the new book the bear, who arrived in the country as a stowaway, is interviewed about his right to stay in England.
He has no papers to prove his identity as his Aunt Lucy arranged for him to hide on a ship's lifeboat from Peru when she went to live in the Home for Retired Bears in Lima.
Mr Bond was working as a BBC cameraman when a bear he bought in Selfridges for his wife on Christmas Eve inspired him to write the original novel.
In that book, the bear is adopted by the Brown family when they spot him amid a pile of mailbags at Paddington station.
