"Now," slid Galtier, as they halted upon the pavement opposite the Hyde Park tube station "what are you going to do? Will you take us back to Madame, or are you going to lie to us further? Now then!"
Boyne saw himself at a dead end.
He had never dreamed that the smart French girl of Melun, who had been paid so handsomely by Ena, would again resume her claims. But, of course, the man Galtier was behind her and had, no doubt, prompted her. Fortunately, they could know nothing of the Morrison affair – or, indeed, of the clever plots which they were conducting against other perfectly innocent victims. Life assurance is always a gamble, but when one can guarantee death within dates then one holds a winning hand every time.
"Madame isn't at home," repeated Boyne sulkily. "Call there on Monday. She'll be back then."
"No, my dear M'sieur Bennett," replied the clerk from the Mairie of Chantilly. "If we call then she will have gone, and so will your wife." And he laughed lightly. "You see, I haven't been in London all these weeks without discovering something about all three of you!"
"But I don't see why you should come over from France to pry into our affairs. What can it benefit you?" asked Boyne, who, though excited, kept cool with difficulty.
"Oh! never fear, it will benefit us. We know how and why old Mr. Martin died so unexpectedly in Chiswick. We shall also know, ere long, how other insured persons have died, mon cher ami. So we had better turn back and have a little business chat with Céline's late mistress, and with your wife. That, perhaps, will clear the atmosphere."
"Ah! I see you want money! Both of you – eh?" snapped Boyne.
"Possibly," was the hesitating reply. "But perhaps it would be to our better advantage to tell the police what we know."
"That's a threat!" cried Boyne indignantly. "I allow no man to threaten me!" he declared boldly. "Go back to Madame's house. You are welcome. I am not her keeper."
"I would prefer to deal with you first, M'sieur Bennett."
"I don't want to have any dealings with a person who holds out threats," was his answer. "Madame paid Céline because she dismissed her without notice," he went on carelessly. "Just act as you wish. And I wish you joy. But please don't bother me further."
He was turning away when the Frenchman rushed after him, and stood on the pavement before him.
"Is this your final decision?" he asked fiercely, as he barred Boyne's way.
"Yes. You've come here to blackmail me," replied Boyne; "but you'll not get a sou out of me. Why should I pay you anything? I don't know you! I've never seen you before in my life!"
"But you will be very pleased to settle," snarled the fellow in English.
"I shan't, and if you are not very careful I'll give you in charge of the police for attempted blackmail."
"You swine!" cried Galtier between his teeth.
"The same to you, my dear friend – and a size larger; a bigger breed!" laughed Boyne defiantly.
Both the man and the girl were silent for a few moments, when the latter suddenly broke out into a torrent of abuse and vituperation.
Her companion tried to calm her, but in French she cried loudly:
"These people are assassins! I know what I overheard on the night when poor Monsieur Martin died. They killed him! And he was always very good to me – poor M'sieur! Madame is a fiend!" she went on. "I do not want her dirty money. I want to see her pay the penalty which all those who murder should pay!"
Boyne saw that his bluff had not succeeded. He had to deal with a very perilous situation. A false step might lead them all to the Old Bailey. The pair had evidently been watching them, and were aware that his wife and Ena were both in the flat.
"Well," he laughed harshly, "you both appear to be on the wrong track. Céline has, it seems, suspicions about something which she once overheard. What it was, I do not know, because I wasn't there; but I tell you, both of you, that as far as I care you can go to the devil! I've nothing to ask of you – nothing to fear!
"You really mean that – eh?" cried the lank, bony Frenchman.
"Certainly I do. Clear out – and now at once, otherwise I'll call the first constable and give you in charge for attempted blackmail!" said Boyne, standing erect before him. "We've had foreign blackmailers here before – lots of them – but we've no use for them in London."
"But Madame paid me to say nothing," urged Céline.
"What Madame did does not concern me in the least," he snapped. "She generously gave you something, I believe, because she considered that she had treated you shabbily. That's all!"
An awkward pause ensued.
"Very well," exclaimed Galtier. "We are enemies. Let it be so!
"Of course we are enemies!" Boyne cried in a defiant tone that rather nonplussed the Frenchman.
"Très bien!" he exclaimed.
"Excellent," said the wily Boyne. "Let it be so, as you say. We are enemies. So go back to Upper Brook Street and find madame. Go and try to blackmail her. Meanwhile I shall call the next constable I meet and give you both in charge as undesirable foreigners."
The Frenchman, however, only laughed in his face, saying:
"Yes, do so, mon cher ami! I fancy you would regret such an action. But we are enemies, and at any rate, I intend to see madame, your friend."
"You want money, eh?" growled Boyne, as they stood together on the kerb.
"Perhaps we do – and perhaps we do not. It all depends upon your attitude – and madame's!" he replied, with mock politeness. "The mystery of the death of Monsieur Martin requires elucidating, and Céline can do that – when it becomes necessary."
"I don't understand you," Boyne said. "What about the old man's death?"
"Now, that's quite enough!" cried Galtier, in impatient anger. "It's no use you, of all men, pleading ignorance, Mr. Bennett. Céline has already had a little present from madame to keep a still tongue, and – "
"And you want a bit more, eh?" asked Boyne bluntly.
"No. That's just where you are mistaken, my friend!" was the Frenchman's reply. "Monsieur Martin died in mysterious circumstances, of which both madame and yourself are well aware, and it is but right that the police should know the truth, otherwise we may have other people dying in a similar manner!"
Those last words of his caused Boyne to wince. For what reason, if not with the object of blackmail, had Henri Galtier and Céline Ténot come to London and tracked them down?
He knew that Ena had been indiscreet in her conversation after old Martin's death, but he had believed that her visit to Melun and the payment to the girl had put matters quite right. It seemed to him, however, that Céline was entirely under the influence of that municipal employé from Chantilly, whose attitude was decidedly hostile.
"Well," Boyne asked of the man, "if you don't want money, what in the devil's name do you want?"
"I want to prevent you from playing any more of your hellish tricks upon innocent people. That's what I want!" was the Frenchman's hard reply, in a tone which left no doubt as to his firm intentions.
CHAPTER XXIII
THE CRY IN THE NIGHT
Marigold, hoping against hope, went each day from Wimbledon to the bank, where she sat adding and subtracting figures – always wondering. Each morning, after a hurried breakfast, she dashed to the station and hung upon a swaying strap till she got to the City. Each evening she repeated the same experience home.
Gerald was missing. No further word had come nom him. She waited as each day passed – waited eagerly, but he gave no sign. Each day she went to eat her frugal meal at the same little place, but his familiar figure never appeared in the doorway, as she knew it so well. His sister had heard nothing, and at Mincing Lane they were beginning to think that he had simply left his post without notice, perhaps in order to better himself.
For Marigold the days passed wearily enough. Where was he? True, he had sent her reassuring telegrams, but even they had ceased! He had given no address, therefore she was unable to reply.
