It was not a pleasant discovery, but it was an important one, and Lushington thought over the best means of following it up. He almost choked with anger as he reflected that if matters went on at this rate, Margaret would soon be going to Logotheti's house without even the nominal protection afforded by little Madame De Rosa. He rode back by the way he had taken outward and passed the Greek's house. The motor car was not there, which was a relief, on the whole.

He went on as far as the Opéra, for he knew from his mother that Margaret's rehearsals were taking place there, by the kindness of the director, who was on very friendly terms with Schreiermeyer. But the motor was not to be seen. Logotheti, who could hardly have entered disguised as his own chauffeur, and who would not leave the machine unguarded in the street, had possibly left Margaret at the door and gone away. Lushington got off his bicycle and went in under the covered way to the stage door.

In answer to his questions, the keeper told him that Mademoiselle da Cordova was rehearsing, and would probably not come out for at least two hours. Lushington asked the man whether he had seen Logotheti. No, he had not; he knew Monsieur Logotheti very well; he knew all the subscribers, and particularly all those who were members of the 'high finance.' Besides, every one in Paris knew Monsieur Logotheti by sight; every one knew him as well as the column in the Place Vendôme. He had not been seen that morning. The doorkeeper, who had absolutely nothing to do just at that hour, was willing to talk; but he had nothing of importance to say. Monsieur Logotheti came sometimes to rehearsals. A few days ago he and Mademoiselle da Cordova had left the theatre together. The keeper smiled, and ventured to suppose that Mademoiselle da Cordova was 'protected' by the 'financier.' Lushington flushed angrily and went away.

It had come already, then; what the man had said this morning, he would say to-morrow and the next day, to any one who cared to listen, including the second-class reporters who go to underlings for information; Margaret's name was already coupled with that of a millionaire who was supposed to protect her. Ten days ago, she had been unassailable, a 'lady'—Lushington did not particularly like the word—a young English girl of honourable birth, protected by no less a personage than Mrs. Rushmore, and defended from calumny by that very powerful organisation for mutual defence under all circumstances, which calls itself society, which wields most of the capital of the world, rewards its humble friends with its patronage and generally kills or ruins its enemies. That was ten days ago. Now, the 'lady' had become an 'artist,' and was public property. The stage doorkeeper of a theatre could smilingly suggest that she was the property of a financier, and no one had a right to hit him between the eyes for saying so. Lushington had been strongly tempted to do that, but he had instantly foreseen the consequences; he would have been arrested for an unprovoked assault, the man would have told his story, the papers would have repeated it with lively comments, and Margaret's name would have been dragged through the mud of a newspaper scandal. So Lushington put his hands in his pockets and went away, which was by far the wisest thing he could do.

He set himself resolutely to think out a plan of action, but like many men of tolerably fertile imagination he was at a loss for any expedient in the presence of urgent need. He could watch Logotheti and Margaret, and they would not easily recognise him, but he was fain to admit that he had nothing to gain by spying on them. He had seen enough and heard enough already to convince him that Margaret had allowed herself to be led into a situation very dangerous for her good name, to say the least. It did not occur to him that Logotheti wished to marry her, still less that he meant to hinder her from singing in public. He could not help thinking of the very worst motives, and he attributed them all to the Greek.

The mild English man of letters was momentarily turned into an avenging demon, breathing wrath and destruction upon his adversary. The most extravagant and reckless crimes looked comparatively easy just then, and very tempting. He thought of getting into Logotheti's cellar with enough dynamite to blow the house, its owner and himself to atoms, not to speak of half the Boulevard Péreire. He fancied himself pounding Logotheti's face quite out of shape with his fists, riddling him with revolver bullets, running him through in all directions with duelling swords, tearing him in pieces with wild horses and hanging him out of his own front window. These vivacious actions all looked possible and delightful to Lushington as he walked up and down his little sitting-room. Then came the cold shower-bath of returning common-sense. He sat down, filled a pipe and lit it.

'I'm an awful ass,' he said aloud to himself, in a reproachful tone.

He wished that some spirit voice would contradict him, but in the absence of any supernatural intervention the statement remained unrefuted. The worst of it was that he had always thought himself clever, and in his critical writings he had sneered in a superior way at the inventions of contemporary novelists. Just then, he would have given his reputation for the talents of the hero in a common detective story. But his mind refused to work in that way, and he watched with growing discouragement the little clouds of smoke that floated upwards to the whitewashed ceiling without leaving the least shadow of a serviceable idea behind them.

He looked disconsolately at the square patent leather toes of his shoes, very dusty from bicycling, and he sadly passed his hand over his smooth-shaven chin; the curious creases in his ready-made trousers, so conspicuously in the wrong place, depressed him still further, and the sight of his broad-brimmed hat, lying on the table, enhanced the melancholy of his reflections. The disguise was admirable, undoubtedly, but it had only helped him to see with his eyes what he had already seen in imagination, and so far as he could guess, it was not likely to help him one step further. At that very moment Margaret was probably seated at Logotheti's table, without even Madame De Rosa to chaperon her, and Logotheti's men-servants were exchanging opinions about her outside the door. Lushington nearly bit through the mouthpiece of his pipe as he thought of that, knowing that he was powerless to interfere. The same thing might go on for a month, and he could not stop it; then Margaret would make her début, and the case would be more hopeless than ever.

The truth was that after launching himself as a disguised detective, he found himself barred from going any further than merely watching his enemy, simply because he was incapable of stooping to a detective's methods of work. He would as soon have lost his hand as have written an anonymous letter or deliberately inveigled Logotheti into a trap, and while he was so carefully concealing himself he longed in reality for open fight, and felt that he had made himself ridiculous in his own eyes. Yet he hesitated to put on his own English clothes and go about as usual, for he had to pass the porter's window on the stairs every time he went out or came in, and such a sudden change in his appearance would certainly make the porter suspect that he was engaged in some nefarious business. Porters are powerful personages in Parisian lodging-houses, and this one would probably inform the police that he had a suspicious lodger; after which Lushington would be watched in his turn and would very probably have trouble. These reflections made him feel more ridiculous than ever.
