“Do you see him?”

“The man in the black coat?”

“Yes! That’s him! He’s been following us for two blocks. Don’t keep looking at him!”

“This is a busy street. Maybe he’s just walking in this direction, too.”

“No way. He looks suspicious. Who wears a black trench coat? It just screams ‘I’m a spy!'”

“If that were true, wouldn’t spies avoid wearing them?”

“No. That’s the beauty of it. Since everyone thinks spies wear black trench coats, anyone wearing one must not be a spy because it would be too obvious. So spies can keep wearing them.”

“You know you sound crazy, right?”

“I’m telling you, there’s something weird about him.”

“And I’m saying he’s just a guy in a black coat walking down the street.”

“You’re too trusting.”

“I’m just not paranoid. Why would he be following us, anyway? I’m not a spy. You’re not a spy. What would he want from us?”

“Maybe we know something. Or maybe he wants to use our identities to break into our work.”

“You work in a library! What would he need your identity for? Anyone can go into a library.”

“That’s not the point. He could be after anything; we just don’t know.”

“You are delusional.”

“Oh no.”

“What now?”

“He’s gone.”

“So?”

“So he must be making his move.”

“Wait. He was suspicious when he was behind us; now he’s more suspicious for not being behind us?”

“Yes!”

“I’m not talking to you anymore.”

They walked along in silence for several moments.

“Okay. What about that woman?”

*Sigh* “What about her?”

“It’s cloudy out, but she’s wearing sunglasses. Don’t you think that’s strange?”

“Argh!”
