“I’ll be damned,” he said after a moment. “Or I should be—for being such a stupid idiot!”

Captain Quill narrowed his eyes. “What are you talking about, Mister Gabriel?”

“I’m not sure yet, Captain,” Mike hedged. “May I borrow these three books?” He held them up in his hands.

“May I be so bold as to ask why, Mister Gabriel?”

“I just want to look at them, sir,” Mike said. “I’ll return them within a few hours.”
