"Still, that is singularly deep guessing——!"

"Well, if you demand greater accuracy, I foresaw exactly what would be the result of your interview with your late secretary, in case you really did care for Miss Marsh. Therefore, I brought about the interview because——"

"You brought it about?" cried Osborne in a crescendo of astonishment.

"Yes. You see I am candid. You are aware that I knew where Miss Marsh could be found, and I might have given you the information direct. But I preferred to write a note telling you that you must depend on Miss Prout for tidings."

"Ah! it was you, then, who sent that note! But how cruel, how savagely cruel! Could you not have told me yourself? Don't you realize that your detestable action has bound me for life to a woman whom—Oh, I hope, since you are about to arrest me, that you will prove me guilty, for if I live, life henceforth will hold nothing for me save Dead Sea fruit!"

He covered his eyes, but Furneaux, whose face was twitching curiously, laid a hand on his knee, and said in a low voice:

"Do not despair. You are not the only man in the world who suffers. I had reasons—and strong reasons—for acting in this manner. One reason was that I was uncertain of the depth of your affection for Miss Marsh, and I wished to be as certain as you have now made me."

"But how on earth could that concern you, the depth or shallowness of my affection for Miss Marsh?" asked Osborne in a white heat of anger and indignation.

"Nevertheless, it did concern me," answered Furneaux dryly; "I cannot, at present, explain everything to you. I had a suspicion that your affection for Miss Marsh was trivial: if it had been, you would then have shown a criminal forgetfulness of the dead woman whom so recently you said you loved. In that event, you would have found me continuing the part I have played in regard to you—anything but a friend. As matters stand, I say I may yet earn your gratitude for what to-day you call my cruelty."

Osborne passed his hands across his eyes wearily.
