"But you will do your best?"

"That goes without saying."

He smiled quizzically as he spoke. For the first time he noticed how attractive his client was. A vague regret flitted across his mind that if he disappeared there would be no one to seek him with such eagerness. He dismissed the thought quickly, however. One in his position had no time for such nonsense. Time was too valuable to be wasted in dreaming. The Woman faded: only the Case remained. He fell to drumming on the desk with his pencil, and Judith realised that he asked nothing further of her. She thanked him and rose. Silently he opened a private door leading to the hallway, bowed courteously as she passed him, and went back to his desk as if he had already forgotten her.

Judith went home at once, and all through the morning, she saw to it that she was not very far from the telephone. Every time it rang her heart pounded a little harder, and each time that the call was not what she hoped it would be, disappointment became a little more keen, the fear of failure a little more pronounced.

The maid who served luncheon reported to the kitchen that her mistress had tasted nothing.

"What did I tell ye?" said the cook with profound mysteriousness, and even the chauffeur's boy, who could not recall that she had told anything, was silenced. "There's things goin' on in this house," she declared impressively, when she observed that the silence about her was respectful, "as how none of ye understand." There was no denial.

At about three o'clock, Judith heard the first news.

"The postmark, of course, told us the general locality," said the placid voice over the telephone, speaking very slowly and distinctly. "I have just heard from one of my operatives who has been investigating the drug-stores in the neighbourhood, that he expects to locate a doctor at any time, who will be able to supply the rest of the information we seek. It may be an hour—perhaps two—perhaps not to-day. But I think I can assure you of ultimate success."

Judith thanked him so calmly that the detective wondered. Had he seen the expression of her face as she hung up the receiver, he would have wondered still more.

But as three o'clock merged into four, and four rolled away into five, with no further report, Judith's restlessness gave place to resignation. And when, just as it was turning dark, the maid announced Imrie, she was able to welcome him as unaffectedly as if not a care clouded her sky.
