Gerald Durrant remained outside the house in Upper Brook Street for more than half an hour. Much puzzled, he stood in a doorway opposite the block of flats into which Boyne had gone.
Marigold was on her way back to Wimbledon Park, and that night he intended to probe the mystery farther.
He waited, and still waited. A neighbouring clock struck the hours. The hall-porter at one o'clock closed the door and switched off the lights, yet Gerald still waited for the insurance agent of Hammersmith to emerge.
That he was known to the hall-porter was apparent, for the man had saluted him. It was strange, to say the least, that the man who was compelled to scrape for a living in Hammersmith should be guest in a fashionable flat in Upper Brook Street.
Bernard Boyne was certainly a man of mystery, for not only did he possess the latchkey of the smart house in Pont Street, but he was also known at that block of expensive flats.
The young fellow lit a fresh cigarette and, leaning against the deep portico of the house opposite, possessed himself in patience. Time went on. A police constable passed and repassed, but did not notice him in the shadow, for he hid his cigarette. All the windows of the great building he was watching were in darkness. It was evident now that Boyne would not come out again before morning.
Yet Durrant, with great pertinacity, waited there through the whole night until, at half-past six, the hall-porter threw open the outer door, and milkmen, the postman, and newspaper boys began to arrive in quick succession. Without bite or sup Gerald waited there till half-past ten, when, full of chagrin at being thus foiled, he was compelled to hurry to his office, getting a wash and a shave on the way.
At lunch he met Marigold as usual, and told her of his failure, whereupon she said:
"I have the afternoon off. I'll go at once and see my aunt, and ascertain when he got back."
This she did, and when that evening Durrant arrived home at Ealing he found a wire awaiting him which told him that when Boyne's housekeeper took him up his early tea as usual, her master had been in bed!
Durrant held his breath. The mystery-man had some means of exit from Upper Brook Street—a back way, without a doubt.
But what was the motive of it all? Why should he pose as penurious in Hammersmith, and wear evening clothes in Mayfair?
That night Durrant went again to Upper Brook Street, and, exploring the rear of the building, found that there was a servants' entrance to the flats which led into a mews, and through a back street. By that Bernard Boyne had, no doubt, walked out while Durrant had been keeping his night vigil.
This fact further impressed both Marigold and her lover that Boyne was not what he represented himself to be.
Durrant set out to probe the mystery, and by dint of ingenious application to the affair, he became on friendly terms with the hall-porter. Truth to tell, Durrant had represented himself to be a demobilised officer who had been in love with a lady who had rented one of the flats. He had discovered her name from the house-agent, and knew that she had married during the war.
From the hall-porter he learned that the man who had passed in was an occasional visitor, but to whom he did not know. He would try and ascertain. The lips of all hall-porters of flats are readily unlocked when their hands are "crossed with silver." And why not? In our post-war civilisation little is effected without a quid pro quo. Even the British Cabinet Minister looks for reward; alas! that it should be so. Patriotism in all the Allied Countries seems synonymous with personal ruin, and those who have realised the fact are the profiteers upon gallant men's lives.
Gerald's discovery at the back of Upper Brook Street brought the pair to a dead end as far as their investigations went.
They met as usual at lunch and discussed the situation. What could be done?
"All I can see, Marigold, is for you to continue your visits constantly to Bridge Place and learn all you can from your aunt," Durrant said. "There is evidently something extraordinary in progress. But what it is we cannot possibly tell without more thorough investigation."
"But what can we do further?" asked the girl.
"I can do nothing just yet, except to receive reports from you," replied Gerald. "You can visit Boyne's house and let me know from time to time what is in progress there."
"But the prisoner upstairs?" she asked. "How can I know more?"
"By watching," was his reply. "Do you know, Marigold, I've been thinking—thinking deeply over the affair. We are both agreed that we intend to fathom the secret of this man. Well, now could you not one evening, when you visit your aunt, be taken suddenly very unwell, and then remain there in the house and watch?"
"Really, Gerald, that's a splendid idea!" exclaimed the girl. "Yet it seems an imposition upon Mr. Boyne."
"I know that. He poses as a man without anything whatever save the commission he collects upon the premiums on the lives of the honest inhabitants of Hammersmith. Yet, as we know, he is in touch with certain people of a much higher class than himself. The house in Pont Street is a great enigma to me. We must elucidate the mystery. That is my object."
"I am ready to work at your orders, Gerald," was the girl's reply, with the genuine love-look in her eyes. "Yes, we will do our utmost to solve this mystery!"
In consequence of this conversation, a few days later Marigold went one afternoon to visit her aunt, old Mrs. Felmore, and in the evening was taken very unwell.
Mr. Boyne, who returned as usual about six o'clock, was told of the girl's illness and went down to the kitchen, where he saw her, and, speaking kindly, asked if he should fetch the doctor.
"No, thank you, Mr. Boyne," the girl answered, rather weakly. "It's awfully good of you, but no doubt I shall be better presently, and able to go home. I have a curious dizziness. It came on quite suddenly."
"Are you subject to it?" he inquired. And then in the next breath asked if he could get her anything.
"My aunt has given me a cup of tea," was her reply. "And I already feel better."
"Don't think of going to Wimbledon to-night unless you feel better," he urged. "Mrs. Felmore can make you up a bed in the spare room."
She thanked him, and though she assured him she would be well enough to go home in an hour or so, she had no intention of returning home that night.
Boyne, on his part, looked weary and worn. His clothes were shabby, and his cheap boots were down at heel and dusty after a long day's tramp in the meaner streets of Hammersmith.
Returning to his sitting-room, he took his bulky insurance books from his pocket. Then he threw off his jacket, sat down to tea in his shirt sleeves, and fed "Nibby," his pet rat.
Mrs. Felmore, like many deaf folk, could tell what was said by watching people's lips. When her employer had left the kitchen, she remarked to her niece:
"Isn't Mr. Boyne a dear nice man? Whenever I feel unwell he is always so ready to get me anything. You know how bad I was with my rheumatism last winter? He wouldn't let me work, but engaged old Mrs. Kirk from the Mall."
"Yes, auntie, he is," Marigold declared. "But I didn't tell him how bad I feel. I really don't know what has come over me."
"Why not let him call the doctor?"
"Oh, no. I'll be all right soon," she said cheerfully; and then she reseated herself in the summer twilight near the open window.
At half-past eight o'clock Bernard Boyne, having washed and changed his clothes, went out.
Marigold fell to wondering where he might be going. It had been arranged that Gerald should be on watch outside the house that night, but when they had met at lunch, he had told her that he was compelled to accompany his principal to Birmingham that afternoon, for a conference was to be held in that city on the following day.
"I may be away for a day or two, dear," he had said. "But in the meanwhile discover all you can."
Boyne went direct from Hammersmith to Pont Street, where he found that his wife had gone out to dinner. She would be back soon after ten, the young man-servant informed him.
Therefore he went to his room and put on evening clothes—a very smartly-cut suit with white waist-coat and mother-of-pearl and diamond buttons. As he stood before the long cheval glass, examining himself after he had tied his cravat and put on his coat, the transformation, he thought, was surely complete. Nobody meeting him in that luxuriously furnished house would ever have recognised in him the trudging, hard-working insurance agent of Hammersmith.
He descended to the drawing-room, but his wife did not return till past ten. She was in a strikingly handsome gown of black-and-gold tissue, with a shimmering ornament in her hair, while around her neck was a rope of splendid pearls.
"Well, Lilla!" he exclaimed pleasantly, as he threw himself lazily into a soft arm-chair. "I'm glad you're back early. Where are we to meet Ena?"
"At Murray's, at eleven. Then we go on to the Carlton to supper," was her reply. "Remember our name to-night is Davidson, and we live at Welsford Hall, in Northamptonshire. Ena wants to introduce us to Mrs. Morrison."
"But Mrs. Morrison is likely to meet one of us again, and it might be awkward," the man remarked, as he slowly lit a cigarette.
"She is not likely to meet us again—except at Ena's house—is she?" said his wife, with a curious expression in her narrow eyes.
"No, I suppose not—if all goes right, and there is no hitch," he said reflectively.
"Hitch! How can there be a hitch?" asked Lilla. "Ena will do her part, while you do yours."
"When does Ena propose that the little affair shall be done?" he asked.
"Next Saturday—if that suits you?"
"Saturday," he repeated again reflectively, as he examined his cigarette. "It will take about nine to ten days, so on the following Monday or Tuesday week it should be complete."
"It ought to be, Bernard. We shall soon be wanting more money, you know. We've been spending freely and investing a lot of late. Ena was here this afternoon. Mrs. Morrison came up from Brighton this morning in order to go to the theatre with her, and meet us at supper afterwards. You can tell her how you hunt with the Fitzwilliam and Lord Exeter's hounds. She knows nothing of fox-hunting, and it will impress her."
"Yes. Ena has told me the woman is just the widow of a Glasgow man who has plenty of money, but who knows practically nothing of English society."
"Why Ena is so keen that we should meet the woman, I can't think," Lilla remarked.
"Well, to tell you the truth, I suggested it," was his reply. "When she invites her to dine we shall be there. It looks better for Ena to have other guests, especially if—well, if anything happened."
"I hope nothing untoward will happen," she exclaimed quickly.
"No," he laughed. "Don't worry, my dear. It is all plain sailing. We shall cash a big cheque before long—depend upon it! But time is getting on. We ought to get along to Murray's and meet them on arrival."
Therefore the pair put on their coats, and a taxi being called, they drove to Murray's, where they awaited the arrival of Mrs. Pollen and her guest.
Ten minutes later they came. The red-haired widow was dressed superbly, and wore wonderful beads of Chinese jade. Her companion, handsome and also well-dressed, expressed delight when her hostess introduced her to her old friends, Mr. and Mrs. Davidson. The latter both became extremely affable, appearing very pleased when Ena told them, what they already knew—namely, that she had reserved a table at the Carlton for supper.
Then the four drove in a taxi to Pall Mall, where they had a very pleasant meal.
Mrs. Morrison, of Carsphairn, was a hard-headed and sensible woman. She cared but little for the so-called excitements of society, but that evening she had greatly enjoyed the play, and now as she gazed around at the smart crowd coming in and taking the tables allotted to them, the daring and often magnificent dresses, and the host of good-looking men, it was something of a novelty to her.
"Before my husband's death I travelled a good deal on the Continent," she explained to Mrs. Davidson. "But nowadays I remain mostly in Scotland. I entertain a few people at Carsphairn for the shooting, but beyond that I live very quietly."
"So do we," Lilla replied. "We are just country cousins. Our place is in the wilds of Northamptonshire, and my husband hunts a good deal."
"Ah! Northamptonshire and Leicestershire are the centre of fox-hunting, are they not?" said the Scotch woman, addressing Mr. Davidson.
"Yes. We have several packs within easy reach, though Welsford, where we live, is, strictly speaking, in the Fitzwilliam country. I love hunting," he added.
"My husband even goes cubbing at four o'clock in the morning sometimes," laughed Mrs. Davidson.
"Ah! He is evidently an enthusiast!" Mrs. Morrison agreed. "My husband was a fisherman, and I confess I had to go with him on some very dull expeditions in the north of Scotland and in Ireland."
"That's the worst of men," Lilla declared. "If they take up hunting, fishing, or golf, it becomes an obsession. They talk of nothing else."
And so the chatter about hunting and hunting men continued, apparently to the intense amusement of Ena Pollen—or "Mrs. Morrison" as she was known to the Manchester solicitor and the doctors who had pronounced her life to be a "first-class" one.
The orchestra was playing one of the latest waltzes, and the big restaurant was filled with chatter and laughter. Surely none who sat there that night and noticed the three ladies and their male companion as they drank their champagne, and ate that supper dish of the London restaurants, mousse de jambon served from the ice, would ever have dreamed that a most diabolical plot was in progress, a conspiracy the most subtle and fiendish that the evil mind of man could ever devise.
Ena Pollen was, of course, the life and soul of the party. Very handsome, with her auburn hair and her bizarre dress, she was regarded by half the people in the restaurant. Some of them knew her by sight as a regular habituée of the smart restaurants and dance-clubs, for it was part of the great game which the heartless trio was playing for her to be remarked and regarded as a woman of outstanding grace and beauty.
Men courted her society, and in more than one instance—if the truth be whispered—had been hurried to the grave in consequence.
The quartette, after a delightful meal, took their coffee and Cointreau at a little table set beneath a palm out in the hall. Mrs. Morrison had become as charmed with Mrs. Davidson as she had been with Ena Pollen.
"You must come up and see me at Carsphairn," she urged Lilla. "No doubt your husband, living in the country, shoots. I can give him some grouse in the season. We have a fair amount of game on our moor at Balmaclellan."
"I shall be delighted, Mrs. Morrison," was Davidson's reply; as he lifted his eyes to Mrs. Pollen they exchanged significant glances.
Then, after a merry chat, Ena suddenly said:
"Can't all three of you dine with me at home one evening? You are not going North yet, are you, Mrs. Morrison? Do come. What about next Saturday?"
"I'm going back to Brighton to-morrow," was her reply.
"But you can easily run up on Saturday. Do. Let us dine early and go to a show together, eh?" she suggested with her usual enthusiasm. "You'll come, Lilla, won't you?"
Mrs. Davidson hesitated. She replied that she feared that she had an engagement that evening, and her husband was certain that he had.
"Oh, now, do come!" urged the Red Widow. "If Mrs. Morrison will come, you really must come."
Then, after a few half-hearted arguments and protests, Mrs. Morrison accepted the invitation and the Davidsons did likewise. And so the quiet little dinner was fixed, Ena promising to get a box at some theatre.
"Then we will go to Murray's or Giro's afterwards," she added.
Later, when Boyne and his wife were together in a taxi on their way to Pont Street, Lilla turned to him, and said:
"It all seems to go well if you can be ready by Saturday. If you can't, then we shall be in the cart!"
"Leave it all to me," he said in a hard, changed voice. "We shall be at Upper Brook Street on Saturday, and I hope we shall be successful. It won't be my fault if we fail."
