The solicitor Standish was a friend of Ormrod"s, and after Quarles had gone had suddenly realized what the inquiry might mean, so had telegraphed a warning.

CHAPTER VII

THE STOLEN AEROPLANE MODEL

It was probably on account of the ac.u.men he had shown in solving the mystery of Arthur Bridwell"s death that the government employed Quarles in the important inquiry concerning a stolen model. For political reasons nothing got into the papers at the time, but now there is no further need of secrecy.

You would have been astonished, I fancy, had you chanced upon us in the empty room at Chelsea on a certain Friday afternoon. No trio of sane persons could have looked more futile. On a paper pad the professor was making odd diagrams which might have represented a cubist"s idea of an aeroplane collision; Zena was looking at her hands as if she had discovered something new and unfamiliar about them; and I was turning the leaves of my pocket book, hoping to get an inspiration.

"The man-servant," said Zena, breaking the silence, which had lasted a long time.

"You have said that a dozen times in the last twenty-four hours," Quarles returned rather shortly, adding after a moment"s pause, as if he were giving us valuable information, "and to-day is Friday."

"It is simply impossible that the servant should know so little," she persisted. "His ignorance is too colossal to be genuine. He doesn"t know whether he was attacked by one person or by half-a-dozen; he is not sure that it wasn"t a woman who seized him; he has no idea what his master kept in the safe or in the cupboard. Well, all I can say is, I do not believe him."

I was inclined to agree with her, but in silence I went on looking through the notes I had made concerning the extraordinary case which must be solved quickly if the solution were to be of any benefit to the country. Quarles was also silent, continuing his work as an amateur cubist.

He had expressed no definite opinion since the case had come into his hands, nor had he laughed at any speculation of mine, a sure sign that he was barren of ideas. I had never known him so reticent.

It was his case entirely, not mine, and the fact that the government had considered he was the only man likely to get to the bottom of the mystery was a recognition of his powers, which pleased him no doubt. Twenty-four hours had elapsed since he had been put in possession of the facts, and although they had been spent in tireless energy by both of us--for he had immediately sent for me--we seemed as far from the truth as ever.

On the previous Tuesday Lady Chilcot had given a dance in her house in Mayfair. Her entertainments always had a political flavor, and on this particular evening her rooms seemed to have been full of conflicting influences.

There was considerable political tension at the time, consequent upon one of those periodical disturbances in the Balkans, and people remarked upon the coolness between the Minister for War and certain amba.s.sadors who were all present at Lady Chilcot"s.

Imagination may have had something to do with this conclusion, but two apparently trivial incidents a.s.sumed importance as regards the case in hand. The Silesian amba.s.sador was seen in very earnest conversation with a young man attached to the Silesian Emba.s.sy; and the Minister of War had b.u.t.tonholed young Lanning.

Of course, we did not know what the Silesians had talked about, but to Lanning the minister had remarked that, in view of the political situation, the experiments which had been witnessed that day might prove to be of supreme importance. Lanning expressed gratification that the experiments had been found convincing, and ventured to hope the government would not delay getting to work.

With the minister"s a.s.surance that the government was keen, Richard Lanning went to find Barbara Chilcot, Lady Chilcot"s daughter, but not to talk about the Minister of War or about any experiments. He was in love with her, and had every reason to believe that she liked him.

She was, however, very cool to him that evening, and sarcastically inquired why he was not in attendance upon Mademoiselle Duplaix as usual.

She only laughed at his denials, and when he suggested that she should ask his friend, Perry Nixon, whether there was any ground for her suspicions, said that when she danced with Mr. Nixon later in the evening she hoped to find something more interesting to talk about than Mademoiselle Duplaix.

Lanning comforted himself with the reflection that if Barbara were indifferent to him she would have said nothing about Yvonne Duplaix, and as he had another dance with her at the end of the program hoped to make his peace then.

When this dance came, however, he could not find her, and afterwards discovered that she had sat it out with the young Silesian. He was angry and felt a little revengeful, but he did not mention Barbara to Perry Nixon when they left the house together and walked to Piccadilly.

He left Nixon at the corner of Bond Street and went to his flat in Jermyn Street.

He found his man, Winbush, lying on the dining-room floor, gagged and half unconscious. The safe in his bedroom had been broken open, important papers had been stolen from it, and a wooden case, which he had locked in a cupboard there, had been taken away.

Fully alive to the gravity of the loss, and oblivious of the fact that neglect would be attributed to him, he immediately telephoned to the Minister of War.

Then he "phoned to Nixon"s rooms in Bond Street, and Nixon came round at once. Up to that time Lanning had said nothing about the experiments to his friend; now he told him the whole story.

Richard Lanning belonged to the Army Flying Corps, and was not only a good airman, but was an authority upon flying machines. For some time past there had been secret trials of various types of stabilizers, and one invention, somewhat altered at Lanning"s suggestion, had proved so successful that safety in flight seemed a.s.sured in the near future.

Detailed plans had been prepared, a working model constructed, and only that afternoon these had been secretly exhibited by Lanning in London to a few members of the government and some War Office officials.

Only four men at the works knew anything about the secret, and even their knowledge was not complete, so it seemed impossible that information could leak out, yet the plans and the working model had been stolen.

Of course Lanning was blamed for having them at his flat; he ought to have taken them back to the works. The fact that this would have meant missing Lady Chilcot"s dance was an added mark against him, and suggested a neglect of duty.

Under the circ.u.mstances publicity was not desirable, and Christopher Quarles was asked to solve the mystery. Instructions were telegraphed to the various ports with a view to preventing the model and the plans being taken out of the country, and, as I have said, the professor and I entered upon a strenuous time.

All our preliminary information naturally came from Lanning, who appeared quite indifferent to his own position so long as the stolen property was recovered.

The man Winbush could throw little light upon the affair. He was in his own room when he had heard a noise in the pa.s.sage and supposed his master had returned earlier than he expected. To make sure, he had gone to the dining-room, but before he could switch on the light he had been seized from behind, a pungent smell was in his nostrils, and he was only just beginning to recover consciousness when his master found him.

He had not seen his a.s.sailants, he could not say how many there were, and he was inclined to think one of them was a woman, he told Quarles, because when he first entered the dining-room there was a faint perfume which suggested a woman"s presence.

"It was like a woman when she is dressed for a party," he said in explanation.

He had seen his master bring in the wooden case that afternoon, but he did not know what it contained.

As Zena said, it sounded a lame story, but Lanning believed it. Winbush had been connected with the family all his life, was devoted to him, and it was not likely he would know what the case contained. Lanning could only suppose that some man at the works had turned traitor, while Mr.

Nixon gave it as his opinion that either France or Germany had pulled the strings of the robbery.

Acting under Quarles"s instructions, I had an interview with Miss Chilcot. She corroborated Lanning"s story in every detail so far as she was concerned, and incidentally I understood there was no more than a lover"s quarrel between them. She had sat out with the young Silesian on purpose to annoy Richard. Certainly they had talked of aeroplaning; it was natural, since two days before she had seen some flying at Ranelagh, but Lanning"s name had not been mentioned. Miss Chilcot knew nothing about the experiments which had taken place, nor was she aware that her lover was responsible for some of the improvements which had been made in stabilizers. Rather inconsequently she was annoyed that he had not confided in her. Miss Chilcot carried with her a faint odor of Parma violets. Quarles had told me to note particularly whether she used any kind of perfume.

I was convinced of two things; first, that she was telling the truth without concealing anything, and, secondly, that Mr. Lanning was likely to marry a very charming but rather exacting young woman. When I said so to Quarles he annoyed me by remarking that some women were capable of making lies sound much more convincing than the truth.

I did not attempt to get an interview with Mademoiselle Duplaix, but I made inquiries concerning her, and had a man watching her movements.

Apparently she was the daughter of a good French family, and was making a prolonged stay with the Payne-Kennedys, who moved in very good society.

You may see their name constantly in the _Morning Post_. It was whispered that they were not above accepting a handsome fee for introducing a protegee into society, a form of log-rolling which is far more prevalent than people imagine. Whether the girl"s entrance into London society had been paid for or not I am unable to say, but she had quickly established herself as a success. It was generally agreed that she was both witty and charming, the kind of girl men easily run after, but not the sort they usually marry.

She had evidently managed to cause dissension in various directions, so the suggestion that there was something of the adventuress about her might be nothing more than a spiteful comment. It justified us in keeping a watch upon her, but I had no definite opinion in the matter, not having seen the lady, and, as Quarles said, a fascinating foreigner is easily called an adventuress.

I also made careful inquiries concerning the young Silesian, and had him pointed out to me. He had recently come from his own capital, and was remaining in London only for a short time. He was a relative of the amba.s.sador, and was not here in any official capacity, it was stated.

This might be true so far as it went, but at the same time he might be connected with the secret service.

The professor said very little about his investigations, and I concluded he had met with no success. He had spent some hours with Lanning at the works, I knew, but if he had tapped any other sources of information he did not mention them.

He was still engaged in his cubist"s drawings when the telephone bell rang.

"I"ll go," he said as Zena jumped up; "I am expecting a message."

He went into the hall, and when he returned told us that Lanning and Nixon were on their way to Chelsea.

"I told them to "phone me if anything happened," he said.

"And you expected to hear from them?" I asked.
