"It is," declared Boyne, with a meaning look towards Ena. "It is never injurious as so many of these green, red and yellow alcoholic and sugar concoctions are."
"No," replied the wealthy owner of Carsphairn. "I quite agree." And she drained her glass with undisguised satisfaction. "It has a most exquisite flavour, and it does one no harm."
Boyne smiled grimly across to his hostess and suggested that they should be going if they wanted to be there at the opening of the revue.
The quartette sat in a box, and greatly enjoyed the medley of songs and dances until, at the close, they went off to a gay supper at Giro's, which they did not leave till nearly two in the morning.
Just before Boyne dropped his wife from a taxi at the corner of Pont Street, he said:
"Well, Lilla! It all went well, didn't it? No hitch. We ought to have some news from Lancaster Gate about Wednesday or Thursday."
"Good!" replied the woman. "We'll wait in patience. Only I do hope it will turn out as we expect."
"It will – never fear! Good-night."
And she stepped out to walk down the street to her own house, while he continued in the taxi to Hammersmith Broadway, where he also alighted.
Then, as he walked home, he muttered to himself:
"It can't fail this time. On Wednesday next we shall hear how beneficial to the health is that most excellent liqueur."
CHAPTER XV
CARRIES THE MYSTERY FARTHER
On Monday, according to a previous arrangement, both Gerald and Marigold obtained leave of absence for the afternoon from their respective principals, and after lunching together as usual, went on the top of an omnibus to Kew, where they walked for an hour in the celebrated gardens. Then they went to Hammersmith to take tea with Mrs. Felmore. The deaf old woman welcomed them warmly, and they sat together in the kitchen, though Gerald could not talk with Marigold's aunt.
The girl, who could speak with her aunt with ease, put to her several questions concerning Mr. Boyne's movements, but learned nothing unusual. She feared to tell the old woman of that uncanny disguise which he adopted when he visited that locked room upstairs, or of that weird, but certainly human cry which she had heard above.
Personally, Gerald suspected the cry to be the result of her vivid imagination. The theory that somebody was imprisoned in that upstairs room was fantastic, but highly improbable, therefore he had dismissed it. Yet presently the old woman made one remark which struck him as curious. In the course of conversation Mrs. Felmore said:
"Poor Mr. Boyne! He does all the good in the world that he can. Only yesterday I found hidden in one of the cupboards in his bedroom a whole lot of tinned stuff – tongues, fruit, jam, biscuits – a host of things that he's got up there on the quiet. I asked him what he was hoarding them up for, and he said that he was sending a big parcel of groceries to a poor widow he knew at Notting Hill Gate."
"Curious to have a store of tinned stuff in his bedroom!" remarked Gerald, at once recollecting the suggestion that somebody might be in hiding upstairs.
"Yes, sir," replied the old woman. "But Mr. Boyne is very eccentric sometimes – very eccentric!"
"In what way?" he asked eagerly.
"Oh! he gets up in the middle of the night and goes up and down stairs – I often see the light under my bedroom door."
Marigold and her lover exchanged glances.
"I wonder what he does?" asked the girl.
"Ah! That I can't say," was the old housekeeper's response. "I asked him one day not long ago, and he simply told me he had woke up, and as he couldn't go to sleep again, he went down to do his accounts."
"Well, this store of food shows him to be of a philanthropic turn of mind," remarked Gerald, with a smile. And then, disregarding the fact that Boyne might return at any moment, he succeeded in getting Mrs. Felmore's permission to slip upstairs and view the collection of preserved foods which was going to the poor widow.
Marigold quickly found it stored in the bottom of a cupboard, covered by an old overcoat and some worn-out shirts, which had apparently been flung in at haphazard.
Gerald's quick glance saw something which further aroused his curiosity – a small brand-new tin tea-kettle and a little enamelled basin. With them was a new roll of absorbent cotton-wool and a quart bottle of cheap port wine, which from its label had been purchased of a local grocer.
"Funny that he should send her a tea-kettle and basin!" remarked Durrant, as he handled them. "And look! What's this?" And he took out a small wooden box about three inches square, such as is used by jewellers to send watches by post. He opened it and within, carefully packed in cotton wool, was a small lens surrounded by a threaded brass ring evidently a portion of some optical instrument.
"Part of a telescope!" the girl exclaimed. "Surely a widow would not require that – however poor she might be!"
"Yes, dear," said her lover, holding the box in his hand and reflecting. "This is a curious hoard, and I am wondering if it is intended for the unknown person who is living in seclusion above."
"Well, Mr. Boyne's explanation to auntie is quite clever, if what you suggest is the solution of the mystery."
"But is not Boyne always clever?" he asked. "That he is leading a double life we have already established. It is now for us to solve the problem of the reason of this locked room upstairs."
"Then you think this has been bought in order to feed somebody who is living up above in silence and seclusion?" she asked.
"It seems like it. But if we watch carefully and see in which direction it disappears, whether inside this house or outside, then we shall begin to penetrate the mystery."
"But how shall we do it?"
"This requires very careful consideration, dear," was his reply. "My own feeling is that you should by some means or other endeavour to spend the next few days here with your aunt, so that you can keep daily watch upon this strange collection of provisions. But we mustn't remain here, for Boyne may return at any moment."
So they descended the stairs to the kitchen, and hardly had they reached it when the heavy tread of the man of mystery was heard in the hall above.
While Mrs. Felmore was upstairs interviewing her employer as to what he required for tea, the lovers held hurried consultation.
When the old woman returned, Gerald rose and motioned to her that he intended to go as perhaps Mr. Boyne would not like to discover him there. He placed his finger upon his lips, shook hands with the deaf housekeeper, and stole out and up the area steps, keeping well out of sight of Boyne's window.
"Mr. Durrant was in a hurry, eh?" asked the old woman.
"Yes, auntie. He was afraid that Mr. Boyne might not like him calling here, so he's gone. But I'm here, and – well, to tell you the truth, auntie, I don't exactly know what to do!"
"Do – why?" asked the old woman, her eyes starting as was her habit when surprised.
"I'm at a loose end, auntie. They want my room over at Wimbledon – but only for a week. Hetty and Jack have come home from their music-hall engagement in Paris, and they've asked me to give up my room for a week. So I've no place to sleep. I've been wondering if Mr. Boyne would mind me coming here. Do you think he'd object?"
"No, I'm sure he wouldn't mind, dear!" she declared. "I'll ask him now – when I go up. He's often inquiring after you."
So when she took up her master's tea a quarter of an hour later, she said:
"Marigold's downstairs, sir. She's in a bit of trouble, sir."
"Trouble! Why?" asked Boyne sharply. "What's the matter? Has she left the bank?"
"Oh, no, sir. It's only because she's turned out of her room at Wimbledon for a week for her brother-in-law and his wife, so she wants to come here and stay with me. Would you have any objection?"
"Of course not, Mrs. Felmore. Tell her to come up and see me now."
Then, when the old woman had gone, his genial attitude instantly changed.
