"I had taken my dressing-case from the rack to get out a novel, and had left it on the seat opposite to mine, and at the end of the compartment farthest from her. And once when I came back from buying her a cup of chocolate, or from some other fool-errand, I found her standing at my end of the compartment with both hands on the dressing-bag. She looked at me without so much as winking an eye, and shoved the case carefully into a corner. 'Your bag slipped off on the floor,' she said. 'If you've got any bottles in it, you had better look and see that they're not broken.'

"And I give you my word, I was such an a.s.s that I did open the case and looked all through it. She must have thought I WAS a Juggins. I get hot all over whenever I remember it. But, in spite of my dulness, and her cleverness, she couldn't gain anything by sending me away, because what she wanted was in the hand-bag, and every time she sent me away the hand-bag went with me.

"After the incident of the dressing-case her manner changed. Either in my absence she had had time to look through it, or, when I was examining it for broken bottles, she had seen everything it held.

"From that moment she must have been certain that the cigar-case, in which she knew I carried the diamonds, was in the bag that was fastened to my body, and from that time on she probably was plotting how to get it from me.

"Her anxiety became most apparent. She dropped the great-lady manner, and her charming condescension went with it. She ceased talking, and, when I spoke, answered me irritably, or at random. No doubt her mind was entirely occupied with her plan. The end of our journey was drawing rapidly nearer, and her time for action was being cut down with the speed of the express-train. Even I, unsuspicious as I was, noticed that something was very wrong with her. I really believe that before we reached Ma.r.s.eilles if I had not, through my own stupidity, given her the chance she wanted, she might have stuck a knife in me and rolled me out on the rails. But as it was, I only thought that the long journey had tired her. I suggested that it was a very trying trip, and asked her if she would allow me to offer her some of my cognac.

"She thanked me and said, 'No,' and then suddenly her eyes lighted, and she exclaimed, 'Yes, thank you, if you will be so kind.'

"My flask was in the hand-bag, and I placed it on my lap and, with my thumb, slipped back the catch. As I keep my tickets and railroad-guide in the bag, I am so constantly opening it that I never bother to lock it, and the fact that it is strapped to me has always been sufficient protection. But I can appreciate now what a satisfaction, and what a torment, too, it must have been to that woman when she saw that the bag opened without a key.

"While we were crossing the mountains I had felt rather chilly and had been wearing a light racing-coat. But after the lamps were lighted the compartment became very hot and stuffy, and I found the coat uncomfortable. So I stood up, and after first slipping the strap of the bag over my head, I placed the bag in the seat next me and pulled off the racing-coat. I don't blame myself for being careless; the bag was still within reach of my hand, and nothing would have happened if at that exact moment the train had not stopped at Arles. It was the combination of my removing the bag and our entering the station at the same instant which gave the Princess Zichy the chance she wanted to rob me.

"I needn't say that she was clever enough to take it. The train ran into the station at full speed and came to a sudden stop. I had just thrown my coat into the rack, and had reached out my hand for the bag. In another instant I would have had the strap around my shoulder. But at that moment the Princess threw open the door of the compartment and beckoned wildly at the people on the platform. 'Natalie!' she called, 'Natalie! here I am. Come here! This way!' She turned upon me in the greatest excitement. 'My maid!' she cried. 'She is looking for me. She pa.s.sed the window without seeing me. Go, please, and bring her back.'

She continued pointing out of the door and beckoning me with her other hand. There certainly was something about that woman's tone which made one jump. When she was giving orders you had no chance to think of anything else. So I rushed out on my errand of mercy, and then rushed back again to ask what the maid looked like.

"'In black,' she answered, rising and blocking the door of the compartment. 'All in black, with a bonnet!'

"The train waited three minutes at Arles, and in that time I suppose I must have rushed up to over twenty women and asked, 'Are you Natalie?'

The only reason I wasn't punched with an umbrella or handed over to the police was that they probably thought I was crazy.

"When I jumped back into the compartment the Princess was seated where I had left her, but her eyes were burning with happiness. She placed her hand on my arm almost affectionately, and said, in a hysterical way, 'You are very kind to me. I am so sorry to have troubled you.'

"I protested that every woman on the platform was dressed in black.

"'Indeed, I am so sorry,' she said, laughing; and she continued to laugh until she began to breathe so quickly that I thought she was going to faint.

"I can see now that the last part of that journey must have been a terrible half-hour for her. She had the cigar-case safe enough, but she knew that she herself was not safe. She understood if I were to open my bag, even at the last minute, and miss the case, I would know positively that she had taken it. I had placed the diamonds in the bag at the very moment she entered the compartment, and no one but our two selves had occupied it since. She knew that when we reached Ma.r.s.eilles she would either be twenty thousand pounds richer than when she left Paris, or that she would go to jail. That was the situation as she must have read it, and I don't envy her her state of mind during that last half-hour.

It must have been h.e.l.l.

"I saw that something was wrong, and, in my innocence, I even wondered if possibly my cognac had not been a little too strong. For she suddenly developed into a most brilliant conversationalist, and applauded and laughed at everything I said, and fired off questions at me like a machine-gun, so that I had no time to think of anything but of what she was saying. Whenever I stirred, she stopped her chattering and leaned toward me, and watched me like a cat over a mouse-hole. I wondered how I could have considered her an agreeable travelling-companion. I thought I would have preferred to be locked in with a lunatic. I don't like to think how she would have acted if I had made a move to examine the bag, but as I had it safely strapped around me again, I did not open it, and I reached Ma.r.s.eilles alive. As we drew into the station she shook hands with me and grinned at me like a Cheshire cat.

"'I cannot tell you,' she said, 'how much I have to thank you for.' What do you think of that for impudence?

"I offered to put her in a carriage, but she said she must find Natalie, and that she hoped we would meet again at the hotel. So I drove off by myself, wondering who she was, and whether Natalie was not her keeper.

"I had to wait several hours for the train to Nice; and as I wanted to stroll around the city I thought I had better put the diamonds in the safe of the hotel. As soon as I reached my room I locked the door, placed the hand-bag on the table, and opened it. I felt among the things at the top of it, but failed to touch the cigar-case. I shoved my hand in deeper, and stirred the things about, but still I did not reach it.

A cold wave swept down my spine, and a sort of emptiness came to the pit of my stomach. Then I turned red-hot, and the sweat sprung out all over me. I wet my lips with my tongue, and said to myself, 'Don't be an a.s.s.

Pull yourself together, pull yourself together. Take the things out, one at a time. It's there, of course, it's there. Don't be an a.s.s.'

"So I put a brake on my nerves and began very carefully to pick out the things, one by one, but, after another second, I could not stand it, and I rushed across the room and threw out everything on the bed. But the diamonds were not among them. I pulled the things about and tore them open and shuffled and rearranged and sorted them, but it was no use. The cigar-case was gone. I threw everything in the dressing-case out on the floor, although I knew it was useless to look for it there. I knew that I had put it in the bag. I sat down and tried to think. I remembered I had put it in the satchel at Paris just as that woman had entered the compartment, and I had been alone with her ever since, so it was she who had robbed me. But how? It had never left my shoulder. And then I remembered that it had--that I had taken it off when I had changed my coat and for the few moments that I was searching for Natalie. I remembered that the woman had sent me on that goose-chase, and that at every other station she had tried to get rid of me on some fool-errand.

"I gave a roar like a mad bull, and I jumped down the stairs, six steps at a time.

"I demanded at the office if a distinguished lady of t.i.tle, possibly a Russian, had just entered the hotel.

"As I expected, she had not. I sprang into a cab and inquired at two other hotels, and then I saw the folly of trying to catch her without outside help, and I ordered the fellow to gallop to the office of the Chief of Police. I told my story, and the a.s.s in charge asked me to calm myself, and wanted to take notes. I told him this was no time for taking notes, but for doing something. He got wrathy at that, and I demanded to be taken at once to his Chief. The Chief, he said, was very busy, and could not see me. So I showed him my silver greyhound. In eleven years I had never used it but once before. I stated, in pretty vigorous language, that I was a Queen's Messenger, and that if the Chief of Police did not see me instantly he would lose his official head. At that the fellow jumped off his high horse and ran with me to his Chief--a smart young chap, a colonel in the army, and a very intelligent man.

"I explained that I had been robbed, in a French railway-carriage, of a diamond-necklace belonging to the Queen of England, which her Majesty was sending as a present to the Czarina of Russia. I pointed out to him that if he succeeded in capturing the thief he would be made for life, and would receive the grat.i.tude of three great powers.

"He wasn't the sort that thinks second thoughts are best. He saw Russian and French decorations sprouting all over his chest, and he hit a bell, and pressed b.u.t.tons, and yelled out orders like the captain of a penny-steamer in a fog. He sent her description to all the city-gates, and ordered all cabmen and railway-porters to search all trains leaving Ma.r.s.eilles. He ordered all pa.s.sengers on outgoing vessels to be examined, and telegraphed the proprietors of every hotel and pension to send him a complete list of their guests within the hour. While I was standing there he must have given at least a hundred orders, and sent out enough commissaires, sergeants de ville, gendarmes, bicycle-police, and plain-clothes Johnnies to have captured the entire German army.

When they had gone he a.s.sured me that the woman was as good as arrested already. Indeed, officially, she was arrested; for she had no more chance of escape from Ma.r.s.eilles than from the Chateau D'If.

"He told me to return to my hotel and possess my soul in peace. Within an hour he a.s.sured me he would acquaint me with her arrest.

"I thanked him, and complimented him on his energy, and left him. But I didn't share in his confidence. I felt that she was a very clever woman, and a match for any and all of us. It was all very well for him to be jubilant. He had not lost the diamonds, and had everything to gain if he found them; while I, even if he did recover the necklace, would only be where I was before I lost them, and if he did not recover it I was a ruined man. It was an awful facer for me. I had always prided myself on my record. In eleven years I had never mislaid an envelope, nor missed taking the first train. And now I had failed in the most important mission that had ever been intrusted to me. And it wasn't a thing that could be hushed up, either. It was too conspicuous, too spectacular. It was sure to invite the widest notoriety. I saw myself ridiculed all over the Continent, and perhaps dismissed, even suspected of having taken the thing myself.

"I was walking in front of a lighted cafe, and I felt so sick and miserable that I stopped for a pick-me-up. Then I considered that if I took one drink I would probably, in my present state of mind, not want to stop under twenty, and I decided I had better leave it alone. But my nerves were jumping like a frightened rabbit, and I felt I must have something to quiet them, or I would go crazy. I reached for my cigarette-case, but a cigarette seemed hardly adequate, so I put it back again and took out this cigar-case, in which I keep only the strongest and blackest cigars. I opened it and stuck in my fingers, but, instead of a cigar, they touched on a thin leather envelope. My heart stood perfectly still. I did not dare to look, but I dug my finger-nails into the leather, and I felt layers of thin paper, then a layer of cotton, and then they scratched on the facets of the Czarina's diamonds!

"I stumbled as though I had been hit in the face, and fell back into one of the chairs on the sidewalk. I tore off the wrappings and spread out the diamonds on the cafe-table; I could not believe they were real. I twisted the necklace between my fingers and crushed it between my palms and tossed it up in the air. I believe I almost kissed it. The women in the cafe stood up on the chairs to see better, and laughed and screamed, and the people crowded so close around me that the waiters had to form a body-guard. The proprietor thought there was a fight, and called for the police. I was so happy I didn't care. I laughed, too, and gave the proprietor a five-pound note, and told him to stand everyone a drink.

Then I tumbled into a fiacre and galloped off to my friend the Chief of Police. I felt very sorry for him. He had been so happy at the chance I gave him, and he was sure to be disappointed when he learned I had sent him off on a false alarm.

"But now that I had found the necklace, I did not want him to find the woman. Indeed, I was most anxious that she should get clear away, for, if she were caught, the truth would come out, and I was likely to get a sharp reprimand, and sure to be laughed at.

"I could see now how it had happened. In my haste to hide the diamonds when the woman was hustled into the carriage, I had shoved the cigars into the satchel, and the diamonds into the pocket of my coat. Now that I had the diamonds safe again, it seemed a very natural mistake. But I doubted if the Foreign Office would think so. I was afraid it might not appreciate the beautiful simplicity of my secret hiding-place. So, when I reached the police-station, and found that the woman was still at large, I was more than relieved.

"As I expected, the Chief was extremely chagrined when he learned of my mistake, and that there was nothing for him to do. But I was feeling so happy myself that I hated to have anyone else miserable, so I suggested that this attempt to steal the Czarina's necklace might be only the first of a series of such attempts by an unscrupulous gang, and that I might still be in danger.

"I winked at the Chief, and the Chief smiled at me, and we went to Nice together in a saloon-car with a guard of twelve carabineers and twelve plain-clothes men, and the Chief and I drank champagne all the way.

We marched together up to the hotel where the Russian Amba.s.sador was stopping, closely surrounded by our escort of carabineers, and delivered the necklace with the most profound ceremony. The old Amba.s.sador was immensely impressed, and when we hinted that already I had been made the object of an attack by robbers, he a.s.sured us that his Imperial Majesty would not prove ungrateful.

"I wrote a swinging personal letter about the invaluable services of the Chief to the French Minister of Foreign Affairs, and they gave him enough Russian and French medals to satisfy even a French soldier. So, though he never caught the woman, he received his just reward."

The Queen's Messenger paused and surveyed the faces of those about him in some embarra.s.sment.

"But the worst of it is," he added, "that the story must have got about; for, while the Princess obtained nothing from me but a cigar-case and five excellent cigars, a few weeks after the coronation the Czar sent me a gold cigar-case with his monogram in diamonds. And I don't know yet whether that was a coincidence, or whether the Czar wanted me to know that he knew that I had been carrying the Czarina's diamonds in my pig-skin cigar-case. What do you fellows think?"

III

Sir Andrew rose, with disapproval written in every lineament.

"I thought your story would bear upon the murder," he said. "Had I imagined it would have nothing whatsoever to do with it, I would not have remained." He pushed back his chair and bowed, stiffly. "I wish you good night," he said.

There was a chorus of remonstrance, and, under cover of this and the Baronet's answering protests, a servant, for the second time, slipped a piece of paper into the hand of the gentleman with the pearl stud. He read the lines written upon it and tore it into tiny fragments.

The youngest member, who had remained an interested but silent listener to the tale of the Queen's Messenger, raised his hand, commandingly.

"Sir Andrew," he cried, "in justice to Lord Arthur Chetney, I must ask you to be seated. He has been accused in our hearing of a most serious crime, and I insist that you remain until you have heard me clear his character."

"You!" cried the Baronet.

"Yes," answered the young man, briskly. "I would have spoken sooner,"

he explained, "but that I thought this gentleman"--he inclined his head toward the Queen's Messenger--"was about to contribute some facts of which I was ignorant. He, however, has told us nothing, and so I will take up the tale at the point where Lieutenant Sears laid it down and give you those details of which Lieutenant Sears is ignorant. It seems strange to you that I should be able to add the sequel to this story.
