Arnold Bennett 
The Grand Babylon Hotel 

Nella, daughter of millionaire Theodore Racksole, orders a dinner of steak and beer at the exclusive Grand Babylon Hotel in London. Her order is refused, so Theodore promptly buys the chef, the kitchen and the whole hotel. But when hotel staff begin to vanish and a German prince goes missing, Nella discovers that murder, blackmail and kidnapping are also on the menu. A rollicking murder mystery from one of the finest writers of the last century.
