"But you know me!" cried Hayden naively. "Of course, of course," as her laughter swelled, "I know you've flattered me to death," the red rising in his tanned cheek, "with all that rot about my grin. But," speaking louder in the effort to drown those trills and ripples of melodious laughter, more elfishly mocking and elusive than ever, "your portrait of me, no matter how grossly exaggerated, is in the main, correct."

"Still talking?" droned the menacing voice of Central.

"But it isn't fair," Hayden continued to protest to the Unknown. "You have me at a disadvantage, and I am going to drop all courtesy and any pretense of good manners. Now, are you ready? Yes? Well then, who are you and what do you want?"

"Who am I? Ah, señor, a waif of the wind, adrift on the night's Plutonian shore; but an hour or two ago, the gale caught me up in Spain and swept me over the seas. Regard me as a voice, merely a voice that would hold speech with so distinguished a naturalist."

"A naturalist!" exclaimed Hayden both disappointed and disconcerted. "You have mistaken your man. I can lay no claims to any scientific accomplishments or achievements."

"Oh, pardon!" There was an affected and exaggerated horror in her tones. "I have made a mistake, oh, a great mistake. I had fancied that you were a collector of butterflies."

Hayden nearly dropped the receiver. There was the smallest of pauses and then he spoke in his accustomed tone, a little cooler and more leisurely than usual, with some fleeting idea of caution.

"Ah, yes, yes, I am somewhat interested in that line. But the fact is known to few. Perhaps you will kindly tell me how you learned of my enthusiasm?"

"Are you quite sure that you may not have mentioned the subject to me yourself." Her voice was full of subtle emphasis.

"No, señorita," he laughed. "That will not do. You can not throw me off the track that way, by trying to make me doubt my memory."
