who was not interested in that precise form of drama, would not be expected to be present, but with a false moustache and a few other touches which his experience as an amateur placed within his easy reach, he was to occupy a stall, an end stall somewhere beneath his wife’s box. At an agreed signal Stephanie would jerk open the catch of the necklace, and as she leaned forward the ornament would trickle off her neck and disappear into the arena beneath. Straithwaite, the only one prepared for anything happening, would have no difficulty in securing it. He would look up quickly as if to identify the box, and with the jewels in his hand walk deliberately out into the passage. Before anyone had quite realized what was happening he would have left the house.
Carrados turned his face from the woman to the man.
“This scheme commended itself to you, Mr Straithwaite?”
“Well, you see, Stephanie is so awfully clever that I took it for granted that the thing would go all right.”
“And three days before, Bellitzer had already reported misrepresentation and that two necklaces had been used!”
“Yes,” admitted Straithwaite, with an air of reluctant candour, “I had a suspicion that Stephanie’s native ingenuity rather fizzled there. You know, Stephanie dear, there is a difference, it seems, between Bombay and Californian pearls.”
“The wretch!” exclaimed the girl, grinding her little teeth vengefully. “And we gave him champagne!”
“But nothing came of it; so it doesn’t matter?” prompted Straithwaite.
“Except that now Markhams’ pearls have gone and they are hinting at all manner of diabolical things,” she wrathfully reminded him.
“True,” he confessed. “That is by way of a sequel, Mr Carrados. I will endeavour to explain that part of the incident, for even yet Stephanie seems unable to do me justice.”
He detached himself from the arm of the chair and lounged across the room to another chair, where he took up exactly the same position.
“On the fatal evening I duly made my way to the theatre—a little late, so as to take my seat unobserved. After I had got the general hang I glanced up occasionally until I caught Stephanie’s eye, by which I knew that she was there all right and concluded that everything was going along quite jollily. According to arrangement, I was to cross the theatre immediately the first curtain fell and standing opposite Stephanie’s box twist my watch chain until it was certain that she had seen me. Then Stephanie was to fan herself three times with her programme. Both, you will see, perfectly innocent operations, and yet conveying to each other the intimation that all was well. Stephanie’s idea, of course. After that, I would return to my seat and Stephanie would do her part at the first opportunity in Act II.
“However, we never reached that. Towards the end of the first act something white and noiseless slipped down and fell at my feet. For the moment I thought they were the pearls gone wrong. Then I saw that it was a glove—a lady’s glove. Intuition whispered that it was Stephanie’s before I touched it. I picked it up and quietly got out. Down among the fingers was a scrap of paper—the corner torn off a programme. On it were pencilled words to this effect:
“‘Something quite unexpected. Can do nothing to-night. Go back at once and wait. May return early. Frightfully worried.—S.’”
“You kept the paper, of course?”
“Yes. It is in my desk in the next room. Do you care to see it?”
“Please.”
Straithwaite left the room and Stephanie flung herself into a charming attitude of entreaty.
“Mr Carrados, you will get them back for us, won’t you? It would not really matter, only I seem to have signed something and now Markhams threaten to bring an action against us for culpable negligence in leaving them in an empty flat.”
“You see,” explained Straithwaite, coming back in time to catch the drift of his wife’s words, “except to a personal friend like yourself, it is quite impossible to submit these clues. The first one alone would raise embarrassing inquiries; the other is beyond explanation. Consequently I have been obliged to concoct an imaginary burglary in our absence and to drop the necklace case among the rhododendrons in the garden at the back, for the police to find.”
“Deeper and deeper,” commented Carrados.
“Why, yes. Stephanie and I are finding that out, aren’t we, dear? However, here is the first note; also the glove. Of course I returned immediately. It was Stephanie’s strategy and I was under her orders. In something less than half-an-hour I heard a motor car stop outside. Then the bell here rang.
“I think I have said that I was alone. I went to the door and found a man who might have been anything standing there. He merely said: ‘Mr Straithwaite?’ and on my nodding handed me a letter. I tore it open in the hall and read it. Then I went into my room and read it again. This is it:
”’Dear T.,—Absolutely ghastly. We simply must put off to-night. Will explain that later. Now what do you think? Bellitzer is here in the stalls and young K. D. has asked him to join us at supper at the Savoy. It appears that the creature is Something and I suppose the D.‘s want to borrow off him. I can’t get out of it and I am literally quaking. Don’t you see, he will spot something? Send me the M. string at once and I will change somehow before supper. I am scribbling this in the dark. I have got the Willoughby’s man to take it. Don’t, don’t fail.—S.’”
“It is ridiculous, preposterous,” snapped Stephanie. “I never wrote a word of it—or the other. There was I, sitting the whole evening. And Teddy—oh, it is maddening!”
“I took it into my room and looked at it closely,” continued the unruffled Straithwaite. “Even if I had any reason to doubt, the internal evidence was convincing, but how could I doubt? It read like a continuation of the previous message. The writing was reasonably like Stephanie’s under the circumstances, the envelope had obviously been obtained from the box-office of the theatre and the paper itself was a sheet of the programme. A corner was torn off; I put against it the previous scrap and they exactly fitted.” The gentleman shrugged his shoulders, stretched his legs with deliberation and walked across the room to look out of the window. “I made them up into a neat little parcel and handed it over,” he concluded.
Carrados put down the two pieces of paper which he had been minutely examining with his finger-tips and still holding the glove addressed his small audience collectively.
“The first and most obvious point is that whoever carried out the scheme had more than a vague knowledge of your affairs, not only in general but also relating to this—well, loan, Mrs Straithwaite.”
“Just what I have insisted,” agreed Straithwaite. “You hear that, Stephanie?”
“But who is there?” pleaded Stephanie, with weary intonation. “Absolutely no one in the wide world. Not a soul.”
“So one is liable to think offhand. Let us go further, however, merely accounting for those who are in a position to have information. There are the officials of the insurance company who suspect something; there is Bellitzer, who perhaps knows a little more. There is the lady in Surrey from whom the pearls were borrowed, a Mr Tantroy who seems to have been consulted, and, finally, your own servants. All these people have friends, or underlings, or observers. Suppose Mr Bellitzer’s confidential clerk happens
