"Thanks, Parker. I've heard of her." Costigan was thinking fast. "Free-lance. No way of telling who she's working for at the moment." This was a statement, not a question.

"Only that it would have to be somebody with a lot of money. Her price is high. That all?"

"That's all, fellows." Then, to Jack and Northrop: "My thought is that you two guys are completely out-classed—out-weighed, out-numbered, out-manned, and out-gunned. Undressed, you're sitting ducks; and if you put out any screens it'll crystallize their suspicions and they'll grab you right then—or maybe even knock you off. You'd better get out of here at full blast; you can't do any more good here, the way things are."

"Sure we can!" Kinnison protested. "You wanted a diversion, didn't you?"

"Yes, but you already...."

"What we've done already isn't a patch to what we can do next. We can set up such a diversion that the boys can walk right on the thionite-carrier's heels without anybody paying any attention. By the way, you don't know yet who is going to carry it, do you?"

"No. No penetration at all."

"You soon will, bucko. Watch our smoke!"

"What do you think you're going to do?" Costigan demanded, sharply.

"This." Jack explained. "And don't try to say no. We're on our own, you know."
