Citizen Orlov
(Book)

"Not every fishmonger can be a secret agent. Journey to an unnamed mountainous country in central Europe at the end of the Great War. Enter Citizen Orlov, a simple fishmonger and an honest, upright citizen, who stumbles into the Ministry of Security, and consequently a hidden world of espionage and secrecy. His first assignment? To safeguard the King when he visits the scenic town of Kufzig. But Orlov soon discovers that his ministry handler, the alluring but-couldn't-possibly-be-a-femme-fatale Agent Zelle, is planning not to protect the King but to assassinate him. Caught in a web of plot and counterplot, confusing loyalties, and explosive betrayals, Orlov finds himself on trial for murder. He has an opportunity to clear his name--but with his friends, mother, and fellow citizens' lives in the balance, freedom comes at a high cost."--,(source of summary not specified)
