Spade thumped Cairo’s wallet with the backs of his fingers and said: “There’s nothing like five thousand dollars here. You’re betting your eyes. You could come in and say you’d pay me a million for a purple elephant, but what in hell would that mean?”

“I see, I see,” Cairo said thoughtfully, screwing up his eyes. “You wish some assurance of my sincerity.” He brushed his red lower lip with a fingertip. “A retainer, would that serve?”

“It might.”

Cairo put his hand out towards his wallet, hesitated, withdrew the hand, and said: “You will take, say, a hundred dollars?”

Spade picked up the wallet and took out a hundred dollars. Then he frowned, said, “Better make it two hundred,” and did.

Cairo said nothing.

“Your first guess was that I had the bird,” Spade said in a crisp voice when he had put the two hundred dollars into his pocket and had dropped the wallet on the desk again. “There’s nothing in that. What’s your second?”

“That you know where it is, or, if not exactly that, that you know it is where you can get it.”

Spade neither denied nor affirmed that: he seemed hardly to have heard it. He asked: “What sort of proof can you give me that your man is the owner?”

“Very little, unfortunately. There is this, though: nobody else can give you any authentic evidence of ownership at all. And if you know as much about the affair as I suppose⁠—or I should not be here⁠—you know that the means by which it was taken from him shows that his right to it was more valid than anyone else’s⁠—certainly more valid than Thursby’s.”
