On June 12, 1940, a man strolled onto the platform at Ireland’s Dingle light railway station and asked some workers when the next train would depart for Tralee.
The men stared at him, and one said, “The last train for Tralee left here 14 years ago. I reckon it might be another 14 years before the next train will leave.”
Two hours later the man, Walter Simon, was in a local jail cell. It turned out he was a German spy who had landed that evening by U-boat at Dingle Bay. His spying career was over.
