"And they are spies?" Malone said. "Real spies?"
"Oh, they're real enough," Boyd said. "We've known about 'em for years, and I finally decided to pick them up for questioning. Maybe they have something to do with all this mess that's bothering everybody."
"You haven't the faintest idea what you mean," Malone said. "Mess is hardly the word."
Boyd snorted. "You go on getting yourself confused," he said, "while some of us do the real work. After all—"
"Never mind the insults," Malone said. "How about the spies?"
"Well," Boyd said, a trifle reluctantly, "they've been working as janitors and maintenance men, and of course we've made sure they haven't been able to get their hands on any really valuable information."
"So they've suddenly turned into criminal masterminds," Malone said. "After being under careful surveillance for years—"
"Well, it's possible," Boyd said defensively.
"Almost anything is possible," Malone said.
