"My name is Micawber when I am in a hole, and I wait for something to turn up. Waiting is occasionally the best way of getting to the end of the journey. We will hear what they have to say, Wigan, and then we shall possibly have to get a move on."
Evidently he had a theory, but he would say nothing about it. He amused himself by explaining that mechanical action, such as drawing meaningless lines and curves, as he had been doing, had the effect of giving the brain freedom to think, and declared that it was during times of this sort of freedom that inspiration most usually came.
He was still engrossed with the subject when Lanning and Nixon arrived.
Quarles introduced them to Zena, saying that she always helped him in his investigations.
"Oh, no, not as a clairvoyant," he said with a smile as both men looked astonished. "She just uses common sense, a very valuable thing in detective work, I can a.s.sure you."
"Are you any nearer a solution?" Lanning asked.
"I thought you had come to give me some information," Quarles returned.
"I have, but--"
"Sit down, then, and to business. I am still wanting facts, which are more useful than all my theories."
"Mademoiselle Duplaix telephoned to me this morning," said Lanning. "A man called on her to-day, a mysterious foreigner. He gave no name, but she thinks he was a Silesian, although he spoke perfect French. He talked to her in French, his English being of a fragmentary kind. He asked her to give him the plans of the new aeroplane. You can imagine her surprise.
When she said she had got no plans he expressed great astonishment and plunged into the whole story of how I had been robbed. Until that moment Mademoiselle knew nothing of what had happened in my flat, but this foreigner had evidently got hold of the whole story."
"Who had told him to call upon her?" Quarles asked.
"In the course of an excited narrative he mentioned two or three names entirely unknown to her, but the man seemed to think that I should have sent her the plans."
"Very curious," Quarles remarked.
"He then became apologetic," Lanning went on, "but all the same left the impression that he did not believe her; in fact, she describes his att.i.tude as rather threatening. It wasn"t until after he had gone that she thought she ought to have him followed, and then it was too late. He was out of the street. Probably he had a motor waiting for him. Then she telephoned to me, but I was out, and have only just received her message.
What do you make of it?"
"It gives a new turn to the affair," said Quarles reflectively. "It leaves an unpleasant doubt whether Mademoiselle Duplaix is as innocent as she ought to be, doesn"t it?"
"I don"t think so."
"Would she have telephoned to Lanning if she were guilty?" said Nixon.
"My experience is that where women are concerned it is very difficult to tell what line of action will be followed. Women are distinctly more subtle than men."
Then after a pause the professor went on: "It is difficult to understand how this foreigner could have made such a mistake. You have told us, Mr.
Lanning, that there is nothing between you and this lady, but Miss Chilcot had her suspicions, remember, which suggests that, without intending to do so, you have paid her attentions which other people have misunderstood. Now, do you think you have given Mademoiselle Duplaix a wrong impression, made her believe, in short, that you cared for her, and so caused her to be jealous and perhaps inclined to be revengeful?"
"I am sure I have not."
"Think well, it is a very important point. For instance, has she ever given you any keepsake, a glove, a handkerchief, something--some trifle she was wearing at a dance when--when you flirted with her? Girls do that kind of thing, so my niece there has told me."
Zena smiled and made no denial.
"Nothing of the kind has happened between Mademoiselle and myself,"
said Lanning.
"And yet there seems to be a distinct attempt on some one"s part to implicate you."
"That is true, and I am quite at a loss to understand it."
"I have wondered whether it is not a clever device to put us off the trail," said Nixon. "Your investigations may have led you nearer the truth than you imagined, Mr. Quarles, and this may be an attempt to set you off on a wrong scent. It seems such an obvious clue, doesn"t it? They would guess that Lanning would communicate with you."
"That hardly explains why they went to Mademoiselle Duplaix, does it?"
"But the fact that she is French may," Nixon answered. "Perhaps I am prejudiced, but I believe Silesia has pulled the strings of this affair, and that would be a very good reason for trying to implicate France. It has occurred to Lanning whether the plot might not be frustrated at the other end of it, so to speak. Lanning thinks it would be a good idea if we went to Silesia."
"What do you think of the idea?" Lanning asked. "I should have our Emba.s.sy there behind me, and I should probably manage to get in touch with the men who are active in Silesia"s secret service. I mentioned it to my chief this morning, and he thought there was a great deal in it, but advised a consultation with you first."
"I think it is a good idea," said Quarles, "and it suggests another one.
I am still a little doubtful about Mademoiselle Duplaix, and I have a strong impression that she could at least tell us more if she would, but that she is afraid of hurting you."
"It is most unlikely."
"Well, let me put it to the test, Mr. Lanning. Just write--let me see, how will it be best to word it? "I am going to Silesia--" By the way, when will you go?"
"I thought to-night."
"It is as well not to waste time," said Quarles. "Then write, "I am going to Silesia to-night. I want you to be perfectly open with the bearer of this note and do whatever he advises. If you would be a true friend to me, tell him everything." Put your ordinary signature to it. With that in my possession I will get to work at once, and if I discover anything of importance, and it should be necessary to stop your journey, I will meet your train to-night."
"It seems like an impertinence," Lanning said as he wrote the note.
"When there is so much at stake I shouldn"t let that worry you,"
said Nixon.
No sooner had they gone than Quarles became alert.
"Now we move, Wigan. First of all, we have an appointment in Kensington, at the Blue Lion, near the church, quite a respectable hostelry."
"Not to meet Mademoiselle Duplaix, surely?"
"No, she can wait. Respectable as it is, I do not suppose Mademoiselle frequents the Blue Lion, but we may find there the man who called upon her this morning."
We took a taxi to Kensington. Every moment seemed to be bursting with importance for Quarles now.
The first person I caught sight of at the Blue Lion was Winbush, evidently waiting for some one. He recognized us, and Quarles went to him.
"You are waiting for Mr. Lanning."
The man hesitated.
"I know," Quarles went on, "because I have just left your master. He is in trouble."
"In trouble!"
"Oh, we shall get him out of it all right. There is some mistake. _I_ have a message for you. Come inside."
