“Oh well—something must be done,” said he decisively. “But didn’t you put something in the seat to RESERVE it?”

“Only that New Statesman—but he’s moved it.”

The man still sat with the invisible sneer–grin on his face, and that peculiar and immovable plant of his Italian posterior.

“Mais—cette place etait RESERVEE—” said Francis, moving to the direct attack.

The man turned aside and ignored him utterly—then said something to the men opposite, and they all began to show their teeth in a grin.

Francis was not so easily foiled. He touched the man on the arm. The man looked round threateningly, as if he had been struck.

“Cette place est reservee—par ce Monsieur—” said Francis with hauteur, though still in an explanatory tone, and pointing to Aaron.

The Italian looked him, not in the eyes, but between the eyes, and sneered full in his face. Then he looked with contempt at Aaron. And then he said, in Italian, that there was room for such snobs in the first class, and that they had not any right to come occupying the place of honest men in the third.

“Gia! Gia!” barked the other passengers in the carriage.

“Loro possono andare prima classa—PRIMA CLASSA!” said the woman woman in the corner, in a very high voice, as if talking to deaf people, and pointing to Aaron’s luggage, then along the train to the first class carriages.

“C’e posto la,” said one of the men, shrugging his shoulders.

There was a jeering quality in the hard insolence which made Francis go very red and Augus very white. Angus stared like a death’s–head behind his monocle, with death–blue eyes.

“Oh, never mind. Come along to the first class. I’ll pay the difference. We shall be much better all together. Get the luggage down, Francis. It wouldn’t be possible to travel with this lot, even if he gave up the seat. There’s plenty of room in our carriage—and I’ll pay the extra,” said Angus.

He knew there was one solution—and only one—Money.

But Francis bit his finger. He felt almost beside himself—and quite powerless. For he knew the guard of the train would jeer too. It is not so easy to interfere with honest third–class Bolognesi in Bologna station, even if they have taken another man’s seat. Powerless, his brow knitted, and looking just like Mephistopheles with his high forehead and slightly arched nose, Mephistopheles in a rage, he hauled down Aaron’s bag and handed it to Angus. So they transferred themselves to the first–class carriage, while the fat man and his party in the third–class watched in jeering, triumphant silence. Solid, planted, immovable, in static triumph.

So Aaron sat with the others amid the red plush, whilst the train began its long slow climb of the Apennines, stinking sulphurous through tunnels innumerable. Wonderful the steep slopes, the great chestnut woods, and then the great distances glimpsed between the heights, Firenzuola away and beneath, Turneresque hills far off, built of heaven–bloom, not of earth. It was cold at the summit–station, ice and snow in the air, fierce. Our travellers shrank into the carriage again, and wrapped themselves round.

“Oh, indeed! Then you think that the Serpentine plays no part in the matter?”

“I think it very unlikely.”

“Then perhaps you will kindly explain how it is that we found this in it?” He opened his bag as he spoke, and tumbled onto the floor a wedding-dress of watered silk, a pair of white satin shoes and a bride’s wreath and veil, all discoloured and soaked in water. “There,” said he, putting a new wedding-ring upon the top of the pile. “There is a little nut for you to crack, Master Holmes.”

“Oh, indeed!” said my friend, blowing blue rings into the air. “You dragged them from the Serpentine?”

“No. They were found floating near the margin by a parkkeeper. They have been identified as her clothes, and it seemed to me that if the clothes were there the body would not be far off.”

“By the same brilliant reasoning, every man’s body is to be found in the neighbourhood of his wardrobe. And pray what did you hope to arrive at through this?”

“At some evidence implicating Flora Millar in the disappearance.”

“I am afraid that you will find it difficult.”

“Are you, indeed, now?” cried Lestrade with some bitterness. “I am afraid, Holmes, that you are not very practical with your deductions and your inferences. You have made two blunders in as many minutes. This dress does implicate Miss Flora Millar.”

“And how?”

“In the dress is a pocket. In the pocket is a card-case. In the card-case is a note. And here is the very note.” He slapped it down upon the table in front of him. “Listen to this:

“You will see me when all is ready. Come at once.

“F. H. M.

Now my theory all along has been that Lady St. Simon was decoyed away by Flora Millar, and that she, with confederates, no doubt, was responsible for her disappearance. Here, signed with her initials, is the very note which was no doubt quietly slipped into her hand at the door and which lured her within their reach.”

“Very good, Lestrade,” said Holmes, laughing. “You really are very fine indeed. Let me see it.” He took up the paper in a listless way, but his attention instantly became riveted, and he gave a little cry of satisfaction. “This is indeed important,” said he.

“Ha! you find it so?”

“Extremely so. I congratulate you warmly.”

Lestrade rose in his triumph and bent his head to look. “Why,” he shrieked, “you’re looking at the wrong side!”

“On the contrary, this is the right side.”

“The right side? You’re mad! Here is the note written in pencil over here.”

“And over here is what appears to be the fragment of a hotel bill, which interests me deeply.”

“There’s nothing in it. I looked at it before,” said Lestrade.
