The Grand Babylon Hotel. by Arnold Bennett

When Theodore Racksole-one of the richest men in America, and consequently the world-sits down in London's Grand Babylon Hotel and orders a beefsteak and a bottle of beer, he isn't aware that he's about to become part of a plot involving blackmail, espionage, murder, the royal families of Europe and his daughter Nella. As he's sucked in to the inner workings of the hotel and its staff he has to make a series of stark choices for the safety of his family and guests.
The Grand Babylon Hotel proceeds at a pace that betrays the novel's roots : it was originally serialized in 1901 in the Golden Penny. It was Arnold Bennett's second novel, and was followed by at least forty works of fiction along with numerous plays and non-fiction works. Since its original publication The Grand Babylon Hotel has remained in print, and it has also been adapted for film and radio.
