When Johanna van Haarlem was reunited with the son she gave up in the Second World War, she welcomed him into her family. But 10 years later she learned he wasn't her son.....but a spy
Johanna was reunited with a man she believed to be her long-lost son, Erwin, who worked as a waiter in London. After a decade, she discovered he was actually Vaclav Jelinek, a Czech spy known as Agent Gragert, sent to infiltrate British society. He was eventually caught and sentenced to prison after Johanna testified against him, but she then began a quest to find the real Erwin.
