Pujol created an identity as a fanatically pro-Nazi Spanish government official who could travel to London on official business; he also obtained a fake Spanish diplomatic passport by fooling a printer into thinking Pujol worked for the Spanish embassy in Lisbon. He contacted Friedrich Knappe-Ratey, an agent in Madrid, codenamed "Frederico". The accepted Pujol and gave him a crash course in espionage (including secret writing), a bottle of invisible ink, a codebook, and £600 for expenses. His instructions were to move to Britain and recruit a network of British agents.
