"Oh! I know that all right. I'm going to join the Major and Gertie again."

"Frank!"

"Yes?... No, not a word, please. You promised you wouldn't. I'm going to join those two again and see what happens."

"But why?"

"That's my job. I know that much. I've got to get that girl back to her people again. She's not his wife, you know."

"But what the devil—"

"It seems to me to matter a good deal. Oh! she's a thoroughly stupid girl, and he's a proper cad; but that doesn't matter. It's got to be done; or, rather, I've got to try to do it. I daresay I shan't succeed, but that, again, doesn't matter. I've got to do my job, and then we'll see."

Jack threw up his hands.

"You're cracked!" he said.

"I daresay," said Frank solemnly.
