It's 1925, and the Empress of Australia sails toward New York with a full passenger manifest. When a body is discovered onboard, Inspector Archie Daniels begins investigating - but one murder becomes two, then three. Racing against time to prevent disaster, Daniels realizes no one is safe, from entitled first-class passengers to those deemed 'dregs of empire' below deck. With nowhere to run on the open Atlantic, the killer remains among them. The Empress Murders delivers a razor-sharp, mind-bendingly clever whodunnit that doubles as a bloodthirsty mystery and scathing examination of British Empire excess as its sun begins setting.
