He was spinning out his sentences, making them intolerably long and lingering, in the hope of maddening the practical little Doctor into an explosion of impatience which might show his hand. But the little Doctor continued only to stare and smile, and the monologue was uphill work. Syme began to feel a new sickness and despair. The Doctor’s smile and silence were not at all like the cataleptic stare and horrible silence which he had confronted in the Professor half an hour before. About the Professor’s makeup and all his antics there was always something merely grotesque, like a gollywog. Syme remembered those wild woes of yesterday as one remembers being afraid of Bogy in childhood. But here was daylight; here was a healthy, square-shouldered man in tweeds, not odd save for the accident of his ugly spectacles, not glaring or grinning at all, but smiling steadily and not saying a word. The whole had a sense of unbearable reality. Under the increasing sunlight the colours of the Doctor’s complexion, the pattern of his tweeds, grew and expanded outrageously, as such things grow too important in a realistic novel. But his smile was quite slight, the pose of his head polite; the only uncanny thing was his silence.

“As I say,” resumed the Professor, like a man toiling through heavy sand, “the incident that has occurred to us and has led us to ask for information about the Marquis, is one which you may think it better to have narrated; but as it came in the way of Comrade Syme rather than me ”

His words he seemed to be dragging out like words in an anthem; but Syme, who was watching, saw his long fingers rattle quickly on the edge of the crazy table. He read the message, “You must go on. This devil has sucked me dry!”

Syme plunged into the breach with that bravado of improvisation which always came to him when he was alarmed.

“Yes, the thing really happened to me,” he said hastily. “I had the good fortune to fall into conversation with a detective who took me, thanks to my hat, for a respectable person. Wishing to clinch my reputation for respectability, I took him and made him very drunk at the Savoy. Under this influence he became friendly, and told me in so many words that within a day or two they hope to arrest the Marquis in France. So unless you or I can get on his track ”

The Doctor was still smiling in the most friendly way, and his protected eyes were still impenetrable. The Professor signalled to Syme that he would resume his explanation, and he began again with the same elaborate calm.

“Syme immediately brought this information to me, and we came here together to see what use you would be inclined to make of it. It seems to me unquestionably urgent that ”

All this time Syme had been staring at the Doctor almost as steadily as the Doctor stared at the Professor, but quite without the smile. The nerves of both comrades-in-arms were near snapping under that strain of motionless amiability, when Syme suddenly leant forward and idly tapped the edge of the table. His message to his ally ran, “I have an intuition.”

The Professor, with scarcely a pause in his monologue, signalled back, “Then sit on it.”

Syme telegraphed, “It is quite extraordinary.”

The other answered, “Extraordinary rot!”

Syme said, “I am a poet.”

The other retorted, “You are a dead man.”

Syme had gone quite red up to his yellow hair, and his eyes were burning feverishly. As he said he had an intuition, and it had risen to a sort of lightheaded certainty. Resuming his symbolic taps, he signalled to his friend, “You scarcely realise how poetic my intuition is. It has that sudden quality we sometimes feel in the coming of spring.”

He then studied the answer on his friend’s fingers. The answer was, “Go to hell! ”

The Professor then resumed his merely verbal monologue addressed to the Doctor.

“Perhaps I should rather say,” said Syme on his fingers, “that it resembles that sudden smell of the sea which may be found in the heart of lush woods.”

His companion disdained to reply.

“Or yet again,” tapped Syme, “it is positive, as is the passionate red hair of a beautiful woman.”

The Professor was continuing his speech, but in the middle of it Syme decided to act. He leant across the table, and said in a voice that could not be neglected

“Dr. Bull!”

The Doctor’s sleek and smiling head did not move, but they could have sworn that under his dark glasses his eyes darted towards Syme.

“Dr. Bull,” said Syme, in a voice peculiarly precise and courteous, “would you do me a small favour? Would you be so kind as to take off your spectacles?”

The Professor swung round on his seat, and stared at Syme with a sort of frozen fury of astonishment. Syme, like a man who has thrown his life and fortune on the table, leaned forward with a fiery face. The Doctor did not move.

For a few seconds there was a silence in which one could hear a pin drop, split once by the single hoot of a distant steamer on the Thames. Then Dr. Bull rose slowly, still smiling, and took off his spectacles.

Syme sprang to his feet, stepping backwards a little, like a chemical lecturer from a successful explosion. His eyes were like stars, and for an instant he could only point without speaking.

The Professor had also started to his feet, forgetful of his supposed paralysis. He leant on the back of the chair and stared doubtfully at Dr. Bull, as if the Doctor had been turned into a toad before his eyes. And indeed it was almost as great a transformation scene.

The two detectives saw sitting in the chair before them a very boyish-looking young man, with very frank and happy hazel eyes, an open expression, cockney clothes like those of a city clerk, and an unquestionable breath about him of being very good and rather commonplace. The smile was still there, but it might have been the first smile of a baby.

“I knew I was a poet,” cried Syme in a sort of ecstasy. “I knew my intuition was as infallible as the Pope. It was the spectacles that did it! It was all the spectacles. Given those beastly black eyes, and all the rest of him his health and his jolly looks, made him a live devil among dead ones.”

“It certainly does make a queer difference,” said the Professor shakily. “But as regards the project of Dr. Bull ”

“Project be damned!” roared Syme, beside himself. “Look at him! Look at his face, look at his collar, look at his blessed boots! You don’t suppose, do you, that that thing’s an anarchist?”

“Syme!” cried the other in an apprehensive agony.

“Why, by God,” said Syme, “I’ll take the risk of that myself! Dr. Bull, I am a police officer. There’s my card,” and he flung down the blue card upon the table.

The Professor still feared that all was lost; but he was loyal. He pulled out his own official card and put it beside his friend’s. Then the third man burst out laughing, and for the first time that morning they heard his voice.

“I’m awfully glad you chaps have come so early,” he said, with a sort of schoolboy flippancy, “for we can all start for France together. Yes, I’m in the force right enough,” and he flicked a blue card towards them lightly as a matter of form.

Clapping a brisk bowler on his head and resuming his goblin glasses, the Doctor moved so quickly towards the door, that the others instinctively followed him. Syme seemed a little distrait, and as he passed under the doorway he suddenly struck his stick on the stone passage so that it rang.

“But Lord God Almighty,” he cried out, “if this is all right, there were more damned detectives than there were damned dynamiters at the damned Council!”

“We might have fought easily,” said Bull; “we were four against three.”

The Professor was descending the stairs, but his voice came up from below.

“No,” said the voice, “we were not four against three we were not so lucky. We were four against One.”
