“Nothing much sir, I’m afraid. I shudder to think of what’s coming. If zwilniks can grow Trenconian broadleaf anywhere. . . .”

“Not at all, not at all,” Ellington interrupted. “If such an entirely unsuspected firm as Tellurian Pharmaceuticals, with all their elaborate preparations and precautions, could not do much more than start, it is highly improbable that any other attempt will be a success. You have given us a very potent weapon against zwilnik operations—not only thionite, but heroin, ladolian, nitrolabe, and the rest.”

“What weapon?” Cloud was puzzled.

“Statistical analysis and correlation of apparently unrelated indices.”

“But they’ve been used for years!”

“Not the way you used them, my friend. Thus, while we cannot count upon any more such extraordinary help as you gave us, we should not need any. Can I give you a lift back to Tellus?”

“I don’t think so, thanks. My stuff is en route now. I’ll have to blow out this vortex anyway. Not that I think there’s anything unusual about it—those were undoubtedly murders, not vortex casualties at all—but for the record. Also, since I can’t do any more extinguishing until my arm finishes itself up, I may as well stay here and keep on practising.”

“Practising? Practising what?”

“Gun-slinging—the lightning draw. I intend to get at least a lunch while the next pirate who pulls a DeLameter on me is getting a square meal.”
