“He’s gone off his head,” said the little Doctor, staring.

“Our bearings,” continued Syme calmly, “are ‘argent a chevron gules charged with three cross crosslets of the field.’ The motto varies.”

The Professor seized Syme roughly by the waistcoat.

“We are just inshore,” he said. “Are you seasick or joking in the wrong place?”

“My remarks are almost painfully practical,” answered Syme, in an unhurried manner. “The house of St. Eustache also is very ancient. The Marquis cannot deny that he is a gentleman. He cannot deny that I am a gentleman. And in order to put the matter of my social position quite beyond a doubt, I propose at the earliest opportunity to knock his hat off. But here we are in the harbour.”

They went on shore under the strong sun in a sort of daze. Syme, who had now taken the lead as Bull had taken it in London, led them along a kind of marine parade until he came to some cafes, embowered in a bulk of greenery and overlooking the sea. As he went before them his step was slightly swaggering, and he swung his stick like a sword. He was making apparently for the extreme end of the line of cafes, but he stopped abruptly. With a sharp gesture he motioned them to silence, but he pointed with one gloved finger to a cafe table under a bank of flowering foliage at which sat the Marquis de St. Eustache, his teeth shining in his thick, black beard, and his bold, brown face shadowed by a light yellow straw hat and outlined against the violet sea.

SYME sat down at a cafe table with his companions, his blue eyes sparkling like the bright sea below, and ordered a bottle of Saumur with a pleased impatience. He was for some reason in a condition of curious hilarity. His spirits were already unnaturally high; they rose as the Saumur sank, and in half an hour his talk was a torrent of nonsense. He professed to be making out a plan of the conversation which was going to ensue between himself and the deadly Marquis. He jotted it down wildly with a pencil. It was arranged like a printed catechism, with questions and answers, and was delivered with an extraordinary rapidity of utterance.

“I shall approach. Before taking off his hat, I shall take off my own. I shall say, ‘The Marquis de Saint Eustache, I believe.’ He will say, ‘The celebrated Mr. Syme, I presume.’ He will say in the most exquisite French, ‘How are you?’ I shall reply in the most exquisite Cockney, ‘Oh, just the Syme’ ”

“Oh, shut it,” said the man in spectacles. “Pull yourself together, and chuck away that bit of paper. What are you really going to do?”

“But it was a lovely catechism,” said Syme pathetically. “Do let me read it you. It has only forty-three questions and answers, and some of the Marquis’s answers are wonderfully witty. I like to be just to my enemy.”

“But what’s the good of it all?” asked Dr. Bull in exasperation.

“It leads up to my challenge, don’t you see,” said Syme, beaming. “When the Marquis has given the thirty-ninth reply, which runs ”

“Has it by any chance occurred to you,” asked the Professor, with a ponderous simplicity, “that the Marquis may not say all the forty-three things you have put down for him? In that case, I understand, your own epigrams may appear somewhat more forced.”

Syme struck the table with a radiant face.

“Why, how true that is,” he said, “and I never thought of it. Sir, you have an intellect beyond the common. You will make a name.”

“Oh, you’re as drunk as an owl!” said the Doctor.

“It only remains,” continued Syme quite unperturbed, “to adopt some other method of breaking the ice (if I may so express it) between myself and the man I wish to kill. And since the course of a dialogue cannot be predicted by one of its parties alone (as you have pointed out with such recondite acumen), the only thing to be done, I suppose, is for the one party, as far as possible, to do all the dialogue by himself. And so I will, by George!” And he stood up suddenly, his yellow hair blowing in the slight sea breeze.

A band was playing in a cafe chantant hidden somewhere among the trees, and a woman had just stopped singing. On Syme’s heated head the bray of the brass band seemed like the jar and jingle of that barrel-organ in Leicester Square, to the tune of which he had once stood up to die. He looked across to the little table where the Marquis sat. The man had two companions now, solemn Frenchmen in frock-coats and silk hats, one of them with the red rosette of the Legion of Honour, evidently people of a solid social position. Besides these black, cylindrical costumes, the Marquis, in his loose straw hat and light spring clothes, looked Bohemian and even barbaric; but he looked the Marquis. Indeed, one might say that he looked the king, with his animal elegance, his scornful eyes, and his proud head lifted against the purple sea. But he was no Christian king, at any rate; he was, rather, some swarthy despot, half Greek, half Asiatic, who in the days when slavery seemed natural looked down on the Mediterranean, on his galley and his groaning slaves. Just so, Syme thought, would the brown-gold face of such a tyrant have shown against the dark green olives and the burning blue.

“Are you going to address the meeting?” asked the Professor peevishly, seeing that Syme still stood up without moving.

Syme drained his last glass of sparkling wine.

“I am,” he said, pointing across to the Marquis and his companions, “that meeting. That meeting displeases me. I am going to pull that meeting’s great ugly, mahogany-coloured nose.”

He stepped across swiftly, if not quite steadily. The Marquis, seeing him, arched his black Assyrian eyebrows in surprise, but smiled politely.

“You are Mr. Syme, I think,” he said.

Syme bowed.

“And you are the Marquis de Saint Eustache,” he said gracefully. “Permit me to pull your nose.”

He leant over to do so, but the Marquis started backwards, upsetting his chair, and the two men in top hats held Syme back by the shoulders.

“This man has insulted me!” said Syme, with gestures of explanation.

“Insulted you?” cried the gentleman with the red rosette, “when?”

“Oh, just now,” said Syme recklessly. “He insulted my mother.”

“Insulted your mother!” exclaimed the gentleman incredulously.

“Well, anyhow,” said Syme, conceding a point, “my aunt.”

“But how can the Marquis have insulted your aunt just now?” said the second gentleman with some legitimate wonder. “He has been sitting here all the time.”

“Ah, it was what he said!” said Syme darkly.

“I said nothing at all,” said the Marquis, “except something about the band. I only said that I liked Wagner played well.”

“It was an allusion to my family,” said Syme firmly. “My aunt played Wagner badly. It was a painful subject. We are always being insulted about it.”

“This seems most extraordinary,” said the gentleman who was decore, looking doubtfully at the Marquis.

“Oh, I assure you,” said Syme earnestly, “the whole of your conversation was simply packed with sinister allusions to my aunt’s weaknesses.”

“This is nonsense!” said the second gentleman. “I for one have said nothing for half an hour except that I liked the singing of that girl with black hair.”

“Well, there you are again!” said Syme indignantly. “My aunt’s was red.”

“It seems to me,” said the other, “that you are simply seeking a pretext to insult the Marquis.”

“By George!” said Syme, facing round and looking at him, “what a clever chap you are!”

The Marquis started up with eyes flaming like a tiger’s.

“Seeking a quarrel with me!” he cried. “Seeking a fight with me! By God! there was never a man who had to seek long. These gentlemen will perhaps act for me. There are still four hours of daylight. Let us fight this evening.”
