Havoc is a fictional novel written by E. Phillips Oppenheim. Havoc arises when European nations start discussing covert alliances. The development of a covert alliance between Germany, Russia, and Austria is the central theme of the narrative. The English want to divide Russia by holding the Czar to his prior public commitments, but they require evidence of the actions taken to put pressure on him. All the factors that contributed to WWI are present, but the intrigues and covert agreements provide an intriguing backdrop for the plot's twists and turns. There will be numerous deaths and a change of ownership before the book is finished. Oppenheim blends a tale of financial failure, murder, and thievery in The City of London into this political backdrop.
