How do you know ?" she smiled.
After a moment he said, still curious: "_Why_ were you crying, Eileen ?" "Crying! I didn't say I was crying." "I assume it." "To prove or disprove that assumption," she said coolly, amused, "let us hunt up a motive for a possible display of tears.

What, Captain Selwyn, have I to cry about?
Is there anything in the world that I lack?
Anything that I desire and cannot have ?" "_Is_ there ?" he repeated.
"I asked you, Captain Selwyn." "And, unable to reply," he said, "I ask you." "And I," she retorted, "refuse to answer." "Oho! So there _is_, then, something you lack?
There _is_ a motive for possible tears ?" "You have not proven it," she said.
"You have not denied it." She tipped back her head, linked her fingers under her chin, and looked at him across the smooth curve of her cheeks.
"Well--yes," she admitted, "I was crying--if you insist on knowing.

Now that you have so cleverly driven me to admit that, can you also force me to tell you _why_ I was so tearful ?" "Certainly," he said promptly; "it was something Nina said that made you cry." They both laughed.
"Oh, what a come-down!" she said teasingly.

"You knew that before.

But can you force me to confess to you _what_ Nina was saying?
If you can you are the cleverest cross-examiner in the world, for I'd rather perish than tell you--" "Oh," he said instantly, "then it was something about love!" He had not meant to say it; he had spoken too quickly, and the flush of surprise on the girl's face was matched by the colour rising to his own temples.
