"The facts are these," she began, with a solemnity of tone that startled him into keener attentiveness. "You found me in MacNutt's office when he was planning and plotting and preparing for the biggest wire-tapping coup in all his career. You were dragged into that plot against your will, almost, just as I had been. But MacNutt gave us our parts, and we worked together there. Then—then you made love to me—don't deny it, Jim, for, after all, it was the happiest part of all my life!—and we both saw how wrong we were, and we both wanted to fight for our freedom. So I followed you when you revolted against MacNutt and his leadership."

"No, Frank, it was you who led—if it hadn't been for you there would never have been any revolt!" he broke in.

"We fought together, then, tooth and nail, and in the end we surrendered everything but our own liberty—just to start over with free hands. But it wasn't our mere escape to freedom that maddened MacNutt; it was the thought that we had beaten him at his own game, that we had stalked him while he was so busy stalking Penfield. Then he trapped us, for a moment, and it was sheer good luck that he didn't kill me that afternoon in his dismantled operating-room, before Doogan and his men attacked the house. But, as you know, he kept after us, and he cornered you again, and you would have killed him, in turn, if I hadn't saved you from the sin of it, and the disgrace of it. Then we thought we were safe, just because the world was big and wide; because we had made our escape to Europe we thought that we were out of his circuit, that we were beyond his key-call—but here we are being led and dragged back to him, through Keenan. But now, just because there is still an ocean between us, you begin to believe that he has given up every thought of getting even!"

"Well, isn't it about time he did? We've beaten him twice, at his own game, and I see no reason why we shouldn't do it again!"

"But how often can we be the glass snake? I mean, how many times can we afford to leave something behind, and break away, and hope to grow whole and sound again? And when will MacNutt get us where we can't break away? I tell you, Jim, you don't know this man as I know him! You haven't understood yet what a cruelly designing and artful and vindictive and long-waiting enemy he can be. You haven't seen him break and crush people, as I once did. It's the memory of that makes me so afraid of him!"

"There's just the trouble, Frank," cried Durkin. "The man has terrified and intimidated you, until you think he is the only enemy you have. I don't deny he isn't dangerous, but so is Pobloff, and so is Doogan, for that matter, and this man Keenan as well!"

"But they would never crush and smash you, as MacNutt will, if the chance comes!" she persisted passionately. "You don't see and understand it, because you are so close to it and so deep in it. It's like traveling along this little Riviera railway. It's so crooked and tunneled and close under the mountains that even though we went up and down it, for a year, from Nice to Nervi, we could never say that we had seen the Riviera!"

Durkin looked out at the terraced hills, at the undulating fields and the heaped masses of blue mountains under the white Italian moonlight, and did not speak for several seconds.

He had always carried, while with her, the vague but sustained sense of being shielded. Until then her hand had always seemed to guard him, impersonally, as the hand of a busy seeker guards and shelters a candle. Now, for some mysterious reason, he felt her brooding guardianship to be something less passive, to be something more immediate and personal. He knew—and he knew it with a full appreciation of the irony that lurked in the situation—that her very timorousness was now endowing him with a new and reckless courage. So he took her hand, gratefully, before he spoke again.

"Well, whatever happens, we are now in this, not from choice, as you said before, but from necessity. If it has dangers, Frank, we must face them."
