When Céline Tènot and Henri Galtier so suddenly appeared outside Ena's flat as the dark shadow of menace at the very moment of the diabolical triumph of the death-dealers, Bernard Boyne realised that, in order to escape, he would have to summon all his wits. The death of old Mr. Martin in Chiswick was an ugly affair—a very ugly affair—and Céline more than suspected—she knew that somehow by the old man's death all three had profited.
At first Boyne was furious to think that Ena's visit to Melun, and the payment of that respectable sum, had been of no avail. But next second, he had seen that the only means of escape was to keep up his identity as Mr. Bennett, to temporise with his pursuers, and then to effect an escape. He saw that, at all hazards, he must prevent the pair of blackmailers from facing Ena and Lilla.
Therefore, when the Frenchman had expressed that hard determination that he wanted to prevent him from playing any more of his "hellish tricks" upon innocent people, he had stood in his path upon the pavement and replied:
"Now, Monsieur Galtier, just pause for a moment—and think! Aren't you a fool? Céline's late mistress has been very good to her, and now you come here and create trouble."
They were standing together against the railings of Hyde Park, not far from the taxi-men's shelter.
"I wish to create no trouble," declared the Frenchman in very good English. "Only trouble for you!" he snarled.
"That is extremely kind of you," Boyne retorted. "But if you still continue to threaten me, I shall take measures to protect myself, and also to retaliate."
"You have denounced me as a blackmailer!" the Frenchman snapped.
"I was wrong," said Boyne apologetically. "I withdraw those words. Naturally at first I believed you wanted more money!"
"Then you believed wrong," was the reply. "Our object in coming to London is to see madame and yourself—and to investigate further the death of Monsieur Martin."
"Well, that you are perfectly at liberty to do," Boyne said, with affected carelessness. "I have nothing whatever to fear. If you like to waste your time and money, do so."
"Céline knows the truth," retorted Galtier.
"Then let her go to the police and tell them. The London police pay little heed to the statements of discharged servants, especially if they are foreigners."
"Yes, I will go!" cried the French girl excitedly. "You are assassins!—assassins! You—both of you!—killed poor Monsieur Martin!"
"I think you will have to prove that," replied Boyne, remaining very calm.
"Hush, Céline!" said her lover. "We do not want a fracas in the street!"
"Bah! The man thinks we are afraid of him. But we are not! We are here to get at the truth about poor monsieur."
"Well, mademoiselle, you are at perfect liberty to institute inquiries," Boyne replied. "But before you go to the police as you threaten, just pause and ask yourself what all this storm in a teacup will profit you and your friend."
The vivacious girl shrugged her shoulders.
"Remember that madame is your friend," he went on. "She told me that she has recently been in Paris, and called upon you in Melun. Madame, since you left, has several times expressed regret to me that she was abrupt."
"Because she believes that I know your secret!" cried mademoiselle, interrupting.
"Let us walk on," suggested Boyne, turning purposely towards Knightsbridge. "There are some people trying to overhear our conversation."
Galtier saw a man and two women who had halted close by, probably attracted by the loud tones in which they were conversing. Strange conversations go on in the London streets at night, as every police constable knows. The night-world of London is an amazing world, of which the honest go-to-bed-early citizen knows nothing. One half the world of London is ignorant of what the other half does o' nights.
They moved on past the taxi shelter towards Knightsbridge, which was in the opposite direction to Upper Brook Street.
"I think you are certainly not fair to madame," Boyne said very quietly to the girl. "She, out of her own generous heart—for no better-hearted woman ever lived—sought you out because she felt that she had treated you unkindly. Of course, I do not know the real facts, but on the face of it I think you, mademoiselle, treated your late mistress with ingratitude. I say this," he went on, "in a perfectly friendly spirit. You may have formed some unfounded suspicion regarding poor Mr. Martin's death. Why, I don't know."
"Because I heard the truth from madame's own lips."
"Some distorted words half overheard, I suppose," he laughed. "My dear mademoiselle, it is always very dangerous to interfere with the death of anybody, because here in England there is such a thing as a law of slander, and of libel—criminal libel, which means that those who make false accusations may be committed to prison. Therefore, before you go further, I advise you to consult a solicitor. He will no doubt advise you."
"We will see the police first," declared Galtier.
"I have not the slightest objection," laughed Boyne. "If you think it will avail you, go to Scotland Yard. That is the head office of the Criminal Investigation Department, but"—and he paused—"but I tell you this, Monsieur, if either of you make any accusations against madame or myself, we shall at once prosecute you—and further, if you escape back to France, we will follow you there and prosecute you. Here, in England, we will not permit foreigners to come over and give the police a lot of trouble for nothing. So make whatever statement you like, but don't forget you will have to substantiate it with witnesses—otherwise you'll probably both find yourselves in prison. That's all I have to say. Good-night!"
And, turning abruptly upon his heel, the master-criminal walked back towards Hyde Park Corner, leaving mademoiselle and her companion utterly perplexed.
Bernard Boyne, as he hurried up Park Lane on his return to Upper Brook Street, muttered to himself:
"I've given them something to think over! They'll hesitate—and while they hesitate, we must act. It would have been fatal for them to have met Ena—and especially to-night—of all nights!"
Ten minutes later he was back in Ena Pollen's room, where she was sitting with Lilla.
"What's happened?" asked his wife, for the paleness of his countenance betrayed that something was amiss.
"Oh! nothing—nothing serious, I mean!" was his reply. "Get me a liqueur brandy," he stammered.
Ena went at once to the dining-room and brought a little glass of old cognac, which he swallowed at a gulp, and then sat for a few moments staring straight before him.
"Tell us, Bernie. What's happened? Where have you been?" demanded his wife.
"Been! I—well, I've been right into the camp of the enemy!" he said hoarsely.
"Enemy! What enemy?"
"Céline is here. Wants to see you. The fellow Galtier is with her. They are on the track of old Martin, and want to see you!"
The two women exchanged glances, for the light in the faces of both had died out.
"Céline here!" gasped Ena. "How much does she know?"
"How can we tell? I've simply defied her."
"But why didn't you offer to pay? They, of course, want money."
Rapidly he described to the two excited women what had occurred. Then at last Lilla said:
"Well, the only thing we can do is to sit tight. We must—if we are to get the money paid on dear Augusta's policy."
"Of course, we can't slip out, or it would be an admission, if Céline really goes to the police."
"There is nothing to prevent her," remarked Ena. "The girl is dangerous."
"So is that girl Ramsay. I've always said so," Lilla declared. "Her lover is out of the way, and the sooner she herself is silenced the better, for as long as that pair are alive they will always be a menace to us."
"I quite agree," said the red-haired widow. "You said that many weeks ago."
"Well, it is all in Bernie's hands. It's no use getting the insurance company to pay without taking due precautions to protect ourselves, is it?" asked Boyne's wife.
The death-dealers thereupon took counsel together. For an hour they sat discussing plans, each putting their idea forward. In the whole of criminal London no three persons were so callous, so ingenious, or so regardless of human life. They had discovered a means of making money with little exertion and with certain results. Boyne, expert as he was in insurance and of a scientific turn of mind, could deal death whenever and wherever he desired, and in such a manner that no coroner's jury could pronounce a verdict other than that death had supervened as a natural cause.
Not before three o'clock in the morning did Lilla and her husband leave Upper Brook Street, and when they did an elaborate and ingenious plan had been decided upon which left no loophole for discovery.
Mrs. Augusta Morrison of Carsphairn had died, and Ena would, of course, excuse herself from going to the funeral. She had mourning which, as a matter of fact, she had worn on more than one occasion when a wealthy friend of hers had died. But in this case she dared not put in an appearance.
At home in Pont Street, Boyne sat with his wife and discussed the situation at considerable length.
"You must get rid of that girl Marigold," she said very emphatically, as she lounged upon the silk-covered sofa in the elegant little room. "She suspects something at Bridge Place, just as her lover suspected. Well, we've successfully sent him off, and he can thank his lucky stars he didn't get a dose."
"I only wish now I had given him a little dose that would have caused him trouble about ten days after he sailed," Boyne said.
"Yes, Bernie. Recollect, I suggested it. They could have buried him at sea, and we should not have been troubled by him any further."
"I was a fool not to take your advice, Lilla."
"You always are. But take my advice about the girl. She's distinctly dangerous! A menace to all of us! And so is your ménage at Hammersmith—especially if Céline really does go to the police. You should end it all, and above everything close Marigold's mouth. That girl is the greatest peril we have before us!"
Her husband, who had lit a cigarette, and was lounging in a chair, agreed with her.
"But," he said, "how am I to do it? We are in a devilish tight corner, Lilla! The game has been a great and very easy one up to now. Nobody has ever yet tumbled to the scientific insurance stunt. And there's lots of money in it. We've found it so. We've got between us eighty thousand or so. A very decent sum. And we could make a million, given a quiet market. Look at the lots of red- or golden-haired women who are wealthy and who are not of any use on earth. Life assurance companies are always on the look-out for business, and pay commission to any and every little tin-pot agent who can put through a proposal. Remember that young fool of a solicitor in Manchester. And there are hundreds about the country everywhere."
"That's so, Bernie," replied his wife in a matter-of-fact tone, she having taken a cigarette to smoke with her husband. "But here we have a peril before us. We were never in such a tight corner before. This may finish us!"
"Oh! my dear Lilla, don't get flurried. I am not. The fellow Durrant is on the high seas as a man who has had a nervous breakdown. Oh, that description! What a godsend it is to us all, isn't it? Nervous breakdown is responsible for a thousand and one evasions of the law—theft, bigamy, assault, forgery—in fact, almost any crime in the calendar can be committed and ascribed to the 'nervous breakdown' of the defendant. We've a lot to be thankful for from the doctors, Lilla," he said, "a lot to be thankful for!"
"Well," she said, puffing thoughtfully at her cigarette, "if the secret of Bridge Place were exposed, then I fear that you couldn't ascribe it to a nervous breakdown, eh?"
Boyne laughed.
"No, Lilla. You are always alive—you are amazingly clever!" he declared. "I did my best with that French girl, Céline, but—well, I'm not quite certain whether she won't go to the police and make a statement."
"Ah! I see," Lilla said quickly. "So we ought to clear out—and quickly."
"Out of London, but not abroad. But not yet. If all of us left suddenly, the insurance company might get scent of a mystery, especially if Céline says anything about old Martin to the police."
"But what of Marigold? Has she any suspicion that Durrant is on the sea?"
"None. Durrant telegraphed to her to urge her to be patient and that he will return. So she's waiting—and she'll wait a long time!
"Ah! really, Bernie, you are wonderful. That was a glorious idea of yours—those telegrams."
"Yes. They've worked well," he said. "Both the girl and his sister, as well as the fellow's employers, have all been reassured."
"But the girl is a menace, I repeat," the woman declared, "and as such you must see that her activity comes to an end. There are a dozen ways in which you can manage it. Adopt one of them, and lose no time about it," she urged.
"Yes," he said in a hard voice, "I ought to have taken your advice long ago."
"Well, take it now," she said. "There are enemies around us—Céline, Galtier, and this girl Ramsay. So be careful. We are in very serious peril!"
"True. How serious we have yet to learn. But let's remain cool and we shall most certainly win."
Almost as he spoke, however, the electric bell at the front door rang, causing them both to start.
"Whoever can it be at this hour?" gasped Lilla, jumping to her feet.
"Wait!" said Boyne, in a changed voice. "I'll go down and see."
He did so. Lilla stood breathless, listening. She heard him unbolt the door and open it.
Then she heard him give vent to a loud cry, half of surprise, half of terror, as a man's deep voice spoke.
