1On the afternoon of the 15th of February a thick yellow fog had settled down on London. Rufus Van Aldin was in his suite at the Savoy and was making the most of the atmospheric conditions by working double time. Knighton was overjoyed. He had found it difficult of late to get his employer to concentrate on the matters in hand. When he had ventured to urge certain courses, Van Aldin had put him off with a curt word. But now Van Aldin seemed to be throwing himself into work with redoubled energy, and the secretary made the most of his opportunities. Always tactful, he plied the spur so unobtrusively that Van Aldin never suspected it.

2Yet in the middle of this absorption in business matters, one little fact lay at the back of Van Aldin's mind. A chance remark of Knighton's, uttered by the secretary in all unconsciousness, had given rise to it. It now festered unseen, gradually reaching further and further forward into Van Aldin's consciousness, until at last, in spite of himself, he had to yield to its insistence.

3He listened to what Knighton was saying with his usual air of keen attention, but in reality not one word of it penetrated his mind. He nodded automatically, however, and the secretary turned to some other papers. As he was sorting them out, his employer spoke:

4"Do you mind telling me that over again, Knighton?"

5For a moment Knighton was at a loss.

6"You mean about this, sir?" He held up a closely written Company report.

7"No, no," said Van Aldin; "what you told me about seeing Ruth's maid in Paris last night. I can't make it out. You must have been mistaken."

8"I can't have been mistaken, sir; I actually spoke to her."

9"Well, tell me the whole thing again."

10Knighton complied.

11"I had fixed up the deal with Bartheimers," he explained, "and had gone back to the Ritz to pick up my traps preparatory to having dinner and catching the nine o'clock train from the Gare du Nord. At the reception desk I saw a woman whom I was quite sure was Mrs. Kettering's maid. I went up to her and asked if Mrs. Kettering was staying there."

12"Yes, yes," said Van Aldin. "Of course. Naturally. And she told you that Ruth had gone on to the Riviera and had sent her to the Ritz to await further orders there?"

13"Exactly that, sir."

14"It is very odd," said Van Aldin. "Very odd, indeed, unless the woman had been impertinent or something of that kind."

15"In that case," objected Knighton, "surely Mrs. Kettering would have paid her down a sum of money, and told her to go back to England. She would hardly have sent her to the Ritz."

16"No," muttered the millionaire; "that's true."

17He was about to say something further, but checked himself. He was fond of Knighton and liked and trusted him, but he could hardly discuss his daughter's private affairs with his secretary. He had already felt hurt by Ruth's lack of frankness, and this chance information which had come to him did nothing to allay his misgivings.

18Why had Ruth got rid of her maid in Paris? What possible object or motive could she have had in so doing?

19He reflected for a moment or two on the curious combination of chance. How should it have occurred to Ruth, except as the wildest coincidence, that the first person that the maid should run across in Paris should be her father's secretary? Ah, but that was the way things happened. That was the way things got found out.

20He winced at the last phrase; it had arisen with complete naturalness to his mind. Was there then "something to be found out"? He hated to put this question to himself; he had no doubt of the answer. The answer was—he was sure of it—Armand de la Roche.

21It was bitter to Van Aldin that a daughter of his should be gulled by such a man, yet he was forced to admit that she was in good company—that other well-bred and intelligent women had succumbed just as easily to the Count's fascination. Men saw through him, women did not.

22He sought now for a phrase that would allay any suspicion that his secretary might have felt.

23"Ruth is always changing her mind about things at a moment's notice," he remarked, and then he added in a would-be careless tone: "The maid didn't give any—er—reason for this change of plan?"

24Knighton was careful to make his voice as natural as possible as he replied:

25"She said, sir, that Mrs. Kettering had met a friend unexpectedly."

26"Is that so?"

27The secretary's practised ears caught the note of strain underlying the seemingly casual tone.

28"Oh, I see. Man or woman?"

29"I think she said a man, sir."

30Van Aldin nodded. His worst fears were being realized. He rose from his chair, and began pacing up and down the room, a habit of his when agitated. Unable to contain his feelings any longer, he burst forth:

31"There is one thing no man can do, and that is to get a woman to listen to reason. Somehow or other, they don't seem to have any kind of sense. Talk of woman's instinct—why, it is well known all the world over that a woman is the surest mark for any rascally swindler. Not one in ten of them knows a scoundrel when she meets one; they can be preyed on by any good-looking fellow with a soft side to his tongue. If I had my way—"

32He was interrupted. A page-boy entered with a telegram. Van Aldin tore it open, and his face went a sudden chalky white. He caught hold of the back of a chair to steady himself, and waved the page-boy from the room.

33"What's the matter, sir?"

34Knighton had risen in concern.

35"Ruth!" said Van Aldin hoarsely.

36"Mrs. Kettering?"

37"Killed!"

38"An accident to the train?"

39Van Aldin shook his head.

40"No. From this it seems she has been robbed as well. They don't use the word, Knighton, but my poor girl has been murdered."

41"Oh, my God, sir!"

42Van Aldin tapped the telegram with his forefinger.

43"This is from the police at Nice. I must go out there by the first train."

44Knighton was efficient as ever. He glanced at the clock.

45"Five o'clock from Victoria, sir."

46"That's right. You will come with me, Knighton. Tell my man, Archer, and pack your own things. See to everything here. I want to go round to Curzon Street."

47The telephone rang sharply, and the secretary lifted the receiver.

48"Yes; who is it?"

49Then to Van Aldin.

50"Mr. Goby, sir."

51"Goby? I can't see him now. No—wait, we have plenty of time. Tell them to send him up."

52Van Aldin was a strong man. Already he had recovered that iron calm of his. Few people would have noticed anything amiss in his greeting to Mr. Goby.

53"I am pressed for time, Goby. Got anything important to tell me?"

54Mr. Goby coughed.

55"The movements of Mr. Kettering, sir. You wished them reported to you."

56"Yes—well?"

57"Mr. Kettering, sir, left London for the Riviera yesterday morning."

58"What?"

59Something in his voice must have startled Mr. Goby. That worthy gentleman departed from his usual practice of never looking at the person to whom he was talking, and stole a fleeting glance at the millionaire.

60"What train did he go on?" demanded Van Aldin.

61"The Blue Train, sir."

62Mr. Goby coughed again and spoke to the clock on the mantelpiece.

63"Mademoiselle Mirelle, the dancer from the Parthenon, went by the same train."
