Ralf Langroth is the pseudonym of an author with translations in fifteen languages. Four of the author’s books are currently optioned for film adaptation by a top-tier production company. In his novel about BKA man Philipp Gerber and journalist Eva Herden, Ralf Langroth combines his two strengths: historically accurate research and the creation of high tension. By telling the story in empty spaces of history, the author enables his readers to experience atmospheric and gripping contemporary espionage thrillers from the young years of the Federal Republic of Germany.
