“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 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 in the corner, in a very high voice, as if talking to deaf people, and 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 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, 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.

My friend was an enthusiastic musician, being himself not only a very capable performer but a composer of no ordinary merit. All All the afternoon he sat in the stalls wrapped in the most perfect happiness, gently waving his long, thin fingers in time to the music, while his gently smiling face and his languid, dreamy eyes were as unlike those of Holmes, the sleuth-hound, Holmes the relentless, keen-witted, ready-handed criminal agent, as it was possible to conceive. In his singular character the dual nature alternately asserted itself, and his extreme exactness and astuteness represented, as I have often thought, the reaction against the poetic and contemplative mood which occasionally predominated in him. The swing of his nature took him from extreme languor to devouring energy; and, as as I knew well, he was never so truly formidable as when, for days on end, he had been lounging in his armchair amid his improvisations and his black-letter editions. Then it was that the lust of the chase would suddenly come upon him, and that his brilliant reasoning power would rise to the level of intuition, until those who were unacquainted with his methods would look askance at him as on a man whose knowledge was not that of other mortals. When I saw him that afternoon so enwrapped in the music at St. James’s Hall I felt that an evil time might be coming upon those whom he had set himself to hunt down.

“You want to go home, no doubt, Doctor,” he remarked as we emerged.

“Yes, it would be as well.”

“And I have some business to do which will take some hours. This business at Coburg Square is serious.”

“Why serious?”

“A considerable crime is in contemplation. I have every reason to believe that we shall be in time to stop it. But to-day being Saturday rather complicates matters. I shall want your help to-night.”

“At what time?”

“Ten will be early enough.”

“I shall be at Baker Street at ten.”

“Very well. And, I say, Doctor, there may be some little danger, so kindly put your army revolver in your pocket.” He waved his hand, turned on his heel, and disappeared in an instant among the crowd.

I trust that I am not more dense than my neighbours, but I was always oppressed with a sense of my own stupidity in my dealings with Sherlock Holmes. Here I had heard what he had heard, I had seen what he had seen, and yet from his words it was evident that he saw clearly not only what had happened but what was about to happen, while to me the whole business was still confused and grotesque. As I drove home to my house in Kensington I thought over it all, from the extraordinary story of the red-headed copier of the Encyclopedia down to the visit to Saxe-Coburg Square, and the ominous words with which he had parted from me. What was this nocturnal expedition, and why should I go armed? Where were we going, and what were we to do? I had the hint from Holmes that this smooth-faced pawnbroker’s assistant was a formidable man — a man who might play a deep game. I tried to puzzle it out, but gave it up in despair and set the matter aside until night should bring an explanation.
