A Detective's Triumph

Peter stepped into General Nolan's office once again, but this time his steps were lighter, almost cheerful.

"What's up? Got some good news?" Nolan looked at the man in front of him, his face devoid of expression.

"No good news, no bad news," Peter shrugged, his expression suggesting his mind was elsewhere.

"Then why do you look so happy?" General Nolan was a sharp man, and it seemed he understood something, a faint smile playing at the corner of his mouth.

"I think... I know who the spy is," Peter said.

"Ah, I see," Nolan understood that the man in front of him had a peculiar way of speaking, first instilling a sense of despair and then offering the most reliable hope.

"So, who is it then?" Nolan asked.

Peter revealed the name of the spy, causing the smile on General Nolan's face to vanish instantly.

"Are you sure?" General Nolan seemed somewhat incredulous.

"Absolutely sure," Peter exaggerated with gestures to emphasize the truth of the news. "If you don't believe me, I have a way to prove it," he added, his mouth splitting into a grin like a crescent moon lying flat on the ground, resembling a clown's wide smile.
