There could be no doubt about it; the necklace was a perfect imitation of the original, even the clasp was an exact copy. Half-hysterical with rage and anxiety, Miss Morgan at once drove to Bond Street, and asked to see Mr Kidd.

“Well, you may easily imagine the stormy interview that took place. Miss Phyllis Morgan, in no measured language, boldly accused Mr Thomas Kidd, late president of the London Chamber of Commerce, of having substituted false pearls for her own priceless ones.

“The worthy jeweller, at first completely taken by surprise, examined the necklace, and was horrified to see that Miss Morgan’s statements were, alas! too true. Mr Kidd was indeed in a terribly awkward position.

“The evening before, after business hours, he had taken the necklace home with him. Before starting for the theatre, he had examined it to see that it was quite in order. He had then, with his own hands, and in the presence of his wife, placed it in its case, and driven straight to the Novelty, where he finally gave it over to Miss Morgan herself.

“To all this he swore most positively; moreover, all his employés and workmen could swear that they had last seen the necklace just after closing time at the shop, when Mr Kidd walked off towards Piccadilly, with the precious article in the inner pocket of his coat.

“One point certainly was curious, and undoubtedly helped to deepen the mystery which to this day clings to the affair at the Novelty Theatre.

“When Mr Kidd handed the packet containing the necklace to Miss Morgan, she was too busy to open it at once. She only spoke to Mr Kidd through her dressing-room door, and never opened the packet till nearly an hour later, after she was dressed ready for the second act; the packet at that time had been untouched, and was wrapped up just as she had had it from Mr Kidd’s own hands. She undid the packet, and handled the pearls; certainly, by the artificial light she could see nothing wrong with the necklace.

“Poor Mr Kidd was nearly distracted with the horror of his position. Thirty years of an honest reputation suddenly tarnished with this awful suspicion – for he realized at once that Miss Morgan refused to believe his statements; in fact, she openly said that she would – unless immediate compensation was made to her – place the matter at once in the hands of the police.

“From the stormy interview in Bond Street, the irate actress drove at once to Scotland Yard; but the old-established firm of Kidd and Co. was not destined to remain under any cloud that threatened its integrity.

“Mr Kidd at once called upon his solicitor, with the result that an offer was made to Miss Morgan, whereby the jeweller would deposit the full value of the original necklace, i.e. £10,000, in the hands of Messrs Bentley and Co., bankers, that sum to be held by them for a whole year, at the end of which time, if the perpetrator of the fraud had not been discovered, the money was to be handed over to Miss Morgan in its entirety.

“Nothing could have been more fair, more equitable, or more just, but at the same time nothing could have been more mysterious.

“As Mr Kidd swore that he had placed the real pearls in Miss Morgan’s hands, and was ready to back his oath by the sum of £10,000, no more suspicion could possibly attach to him. When the announcement of his generous offer appeared in the papers, the entire public approved and exonerated him, and then turned to wonder who the perpetrator of the daring fraud had been.

“How came a valueless necklace in exact imitation of the original one to be in Miss Morgan’s dressing-room? Where were the real pearls? Clearly the loafer who had drugged the stage doorkeeper, and sneaked into the theatre to steal a necklace, was not aware that he was risking several years’ hard labour for the sake of a worthless trifle. He had been one of the many dupes of this extraordinary adventure.

“Macpherson, one of the most able men on the detective staff, had, indeed, his work cut out. The police were extremely reticent, but, in spite of this, one or two facts gradually found their way into the papers, and aroused public interest and curiosity to its highest pitch.

“What had transpired was this:

“Clara Knight, the dresser, had been very rigorously cross-questioned, and, from her many statements, the following seemed quite positive.

“After the curtain had rung up for the second act, and Miss Morgan had left her dressing-room, Knight had waited about for some time, and had even, it appears, handled and admired the necklace. Then, unfortunately, she was seized with the burning desire of seeing the famous scene from the wings. She thought that the place was quite safe, and that George Finch was as usual at his post.

“‘I was going along the short passage that leads to the wings,’ she exclaimed to the detectives, ‘when I became aware of someone moving some distance behind me. I turned and saw a blue domino about to enter Miss Morgan’s dressing-room.

“‘I thought nothing of that,’ continued the girl, ‘as we all know that Mr Dennis is engaged to Miss Morgan. He is very fond of “walking on” in the ballroom scene, and he always wears a blue domino when he does; so I was not at all alarmed. He had his mask on as usual, and he was carrying a bunch of roses. When he saw me at the other end of the passage, he waved his hand to me and pointed to the flowers. I nodded to him, and then he went into the room.’

“These statements, as you may imagine, created a great deal of sensation; so much so, in fact, that Mr Kidd, with his £10,000 and his reputation in mind, moved heaven and earth to bring about the prosecution of Mr Dennis for theft and fraud.

“The papers were full of it, for Mr Howard Dennis was well known in fashionable London society. His answer to these curious statements was looked forward to eagerly; when it came it satisfied no one and puzzled everybody.

“‘Miss Knight was mistaken,’ he said most emphatically, ‘I did not bring any roses for Miss Morgan that night. It was not I that she saw in a blue domino by the door, as I was on the stage before the curtain was rung up for the second act, and never left it until the close.’

“This part of Howard Dennis’ statement was a little difficult to substantiate. No one on the stage could swear positively whether he was ‘on’ early in the act or not, although, mind you, Macpherson had ascertained that in the whole crowd of supers on the stage, he was the only one who wore a blue domino.

“Mr Kidd was very active in the matter, but Miss Morgan flatly refused to believe in her fiancée’s guilt. The worthy jeweller maintained that Mr Howard Dennis was the only person who knew the celebrated pearls and their quaint clasp well enough to have a facsimile made of them, and that when Miss Knight saw him enter the dressing-room, he actually substituted the false necklace for the real one; while the loafer who drugged George Finch’s beer was – as everyone supposed – only a dupe.

“Things had reached a very acute and painful stage, when one more detail found its way into the papers, which, whilst entirely clearing Mr Howard Dennis’ character, has helped to make the whole affair a hopeless mystery.

“Whilst questioning George Finch, Macpherson had ascertained that the stage door-keeper had seen Mr Dennis enter the theatre some time before the beginning of the celebrated second act. He stopped to speak to George Finch for a moment or two, and the latter could swear positively that Mr Dennis was not carrying any roses then.

“On the other hand a flower-girl, who was selling roses in the neighbourhood of the Novelty Theatre late that memorable night, remembers selling some roses to a shabbily dressed man, who looked like a labourer out of work. When Mr Dennis was pointed out to her she swore positively that it was not he.

“‘The man looked like a labourer,’ she explained. ‘I took particular note of him, as I remember thinking that he didn’t look much as if he could afford to buy roses.’

“Now you see,” concluded the man in the corner excitedly, “where the hitch lies. There is absolutely no doubt, judging from the evidence of George Finch and of the flower-girl, that the loafer had provided himself with the roses, and had somehow or other managed to get hold of a blue domino, for the purpose of committing the theft.
