But he attacked it; he attacked it with all the vigor and imagination of a keen, resolute brain, backed by the passionate yearning of his soul. But dark mists of confusion obscured the light he sought—mists of confusion and seeming impossibility through which he must grope and flounder his way.

For a long time there seemed no promise. A dozen times hope fell headlong and died the death. But with each rebuff he started afresh at the given point that—Vita was in enemy hands, whose will she was forced to obey.

After long hours of defeat his efforts wearied. His power of concentration lessened. He found himself repeating over and over again his formula without advancing one single step. Bodily fatigue was helping to oppress his mental faculties. He was growing sleepy. Again and again he strove to rouse himself. But the net results of his effort was a continuation of the idiotic repetition of his formula.

He was not really aware of these things. Mental and bodily weariness had completely supervened. Another few minutes and—— But something galvanized him into complete wakefulness. His weariness fell from him, and he started up in his chair alert—vigorously alert. By some extraordinary subconscious effort he had become aware that his formula had changed. He was no longer repeating it in full—only the latter portion of it: "Whose will she is forced to obey." And as he thought of them now the words rang with a new and powerful significance.

It was the spark of light he had so long sought, and it had leapt out at him from amidst the deep mists of confusion.

So it was that when eleven o'clock came, and the hall gong clanged below, Ruxton went himself to admit his visitor from Scotland Yard. His whole aspect had completely changed from the dispirited creature who had curtly refused to consider matters which Heathcote had placed before him some hours previously.

Inspector Purdic was a smiling, dark man of athletic build and decided manner. He was by no means of senior rank in his profession. But his reputation was unique amongst his colleagues. It was said of him that his record could be divided into two parts, as everybody else's could, but with this difference: his failures came during his early days of inexperience, and could be marked off with a sharp line of division. Beneath that line was nothing but a list of successes.

The officer's manner was deferential. He had had to deal with many men of considerable position. But this was the first time he had been brought into contact with a Cabinet Minister, even of junior rank.

He felt that it was a fresh step up the ladder he had set for his own climbing. He had made his visit there late in the hope that the Cabinet Minister might be induced to give him a protracted and uninterrupted interview, and was pleasantly surprised at the manner in which his explanation was received.

"You see, sir," he said, "it's always a difficulty with us, dealing with a busy public man. So I took a chance, because there's got to be a lot of close talk done."
