My adventures as a German secret agent

A first-person memoir recounts a decade of clandestine diplomacy and covert operations carried out by a German agent, including impersonation to obtain sensitive treaties, theft and careless handling of documents with deadly consequences, and active involvement in Mexican revolutionary affairs. The narrative details schemes to exploit neutrality, attempts to sabotage Allied infrastructure such as a canal plot, coordination with operatives and sympathizers in the United States and Latin America, arrest and imprisonment in England, and the eventual exposure of a spy network through captured papers and sworn statements.
