Arrowheads of the Stone Age and medieval rapiers were ranged alongside some of the latest examples of the gunsmith's art. There were elephants' tusks and Mexican skulls; a stone jar of water from the well of Zem-Zem, and an ivory crucifix which had belonged to Torquemada. A mat of human hair from Borneo overlay a historical and unique rug woven in Ispahan and entirely composed of fragments of Holy Carpets from the Kaaba at Mecca.
"I take it," said Mr. Brinn, suddenly, "that you are up against a stiff proposition."
Paul Harley, accepting a cigarette from an ebony box (once the property of Henry VIII) which the speaker had pushed across the coffee table in his direction, stared up curiously into the sallow, aquiline face. "You are right. But how did you know?"
"You look that way. Also—you were followed. Somebody knows you've come here."
Harley leaned forward, resting one hand upon the table. "I know I was followed," he said, sternly. "I was followed because I have entered upon the biggest case of my career." He paused and smiled in a very grim fashion. "A suspicion begins to dawn upon my mind that if I fail it will also be my last case. You understand me?"
"I understand absolutely," replied Nicol Brinn. "These are dull days. It's meat and drink to me to smell big danger."
Paul Harley lighted a cigarette and watched the speaker closely the while. His expression, as he did so, was an odd one. Two courses were open to him, and he was mentally debating their respective advantages.
"I have come to you to-night, Mr. Brinn," he said finally, "to ask you a certain question. Unless the theory upon which I am working is entirely wrong, then, supposing that you are in a position to answer my question I am logically compelled to suppose, also, that you stand in peril of your life."
"Good," said Mr. Brinn. "I was getting sluggish." In three long strides he crossed the room and locked the door. "I don't doubt Hoskins's honesty," he explained, reading the inquiry in Harley's eyes, "but an A1 intelligence doesn't fold dress pants at thirty-nine."
Only one very intimate with the taciturn speaker could have perceived any evidence of interest in that imperturbable character. But Nicol Brinn took his cheroot between his fingers, quickly placed a cone of ash in a little silver tray (the work of Benvenuto Cellini), and replaced the cheroot not in the left but in the right corner of his mouth. He was excited.
"You are out after one of the big heads of the crook world," he said. "He knows it and he's trailing you. My luck's turned. How can I help?"
Harley stood up, facing Mr. Brinn. "He knows it, as you say," he replied, "and I hold my life in my hands. But from your answer to the question which I have come here to-night to ask you, I shall conclude whether or not your danger at the moment is greater than mine."
"Good," said Nicol Brinn.
In that unique room, at once library and museum, amid relics of a hundred ages, spoil of the chase, the excavator, and the scholar, these two faced each other; and despite the peaceful quiet of the apartment up to which as a soothing murmur stole the homely sounds of Piccadilly, each saw in the other's eyes recognition of a deadly peril. It was a queer, memorable moment.
"My question is simple but strange," said Paul Harley. "It is this: What do you know of 'Fire-Tongue'?"
Chapter 5 THE GATES OF HELL
If Paul Harley had counted upon the word "Fire-Tongue" to have a dramatic effect upon Nicol Brinn, he was not disappointed. It was a word which must have conveyed little or nothing to the multitude and which might have been pronounced without perceptible effect at any public meeting in the land. But Mr. Brinn, impassive though his expression remained, could not conceal the emotion which he experienced at the sound of it. His gaunt face seemed to grow more angular and his eyes to become even less lustrous.
"Fire-Tongue!" he said, tensely, following a short silence. "For God's sake, when did you hear that word?"
"I heard it," replied Harley, slowly, "to-night." He fixed his gaze intently upon the sallow face of the American. "It was spoken by Sir Charles Abingdon."
Closely as he watched Nicol Brinn while pronouncing this name he could not detect the slightest change of expression in the stoic features.
"Sir Charles Abingdon," echoed Brinn; "and in what way is it connected with your case?"
"In this way," answered Harley. "It was spoken by Sir Charles a few moments before he died."
Nicol Brinn's drooping lids flickered rapidly. "Before he died! Then Sir Charles Abingdon is dead! When did he die?"
"He died to-night and the last words that he uttered were 'Fire-Tongue'—" He paused, never for a moment removing that fixed gaze from the other's face.
"Go on," prompted Mr. Brinn.
"And 'Nicol Brinn.'"
Nicol Brinn stood still as a carven man. Indeed, only by an added rigidity in his pose did he reward Paul Harley's intense scrutiny. A silence charged with drama was finally broken by the American. "Mr. Harley," he said, "you told me that you were up against the big proposition of your career. You are right."
With that he sat down in an armchair and, resting his chin in his hand, gazed fixedly into the empty grate. His pose was that of a man who is suddenly called upon to review the course of his life and upon whose decision respecting the future that life may depend. Paul Harley watched him in silence.
"Give me the whole story," said Mr. Brinn, "right from the beginning." He looked up. "Do you know what you have done to-night, Mr. Harley?"
Paul Harley shook his head. Swiftly, like the touch of an icy finger, that warning note of danger had reached him again.
"I'll tell you," continued Brinn. "You have opened the gates of hell!"
Not another word did he speak while Paul Harley, pacing slowly up and down before the hearth, gave him a plain account of the case, omitting all reference to his personal suspicions and to the measures which he had taken to confirm them.
He laid his cards upon the table deliberately. Whether Sir Charles Abingdon had uttered the name of Nicol Brinn as that of one whose aid should be sought or as a warning, he had yet to learn. And by this apparent frankness he hoped to achieve his object. That the celebrated American was in any way concerned in the menace which had overhung Sir Charles he was not prepared to believe. But he awaited with curiosity that explanation which Nicol Brinn must feel called upon to offer.
"You think he was murdered?" said Brinn in his high, toneless voice.
"I have formed no definite opinion. What is your own?"
"I may not look it," replied Brinn, "but at this present moment I am the most hopelessly puzzled and badly frightened man in London."
"Frightened?" asked Harley, curiously.
"I said frightened, I also said puzzled; and I am far too puzzled to be able to express any opinion respecting the death of Sir Charles Abingdon. When I tell you all I know of him you will wonder as much as I do, Mr. Harley, why my name should have been the last to pass his lips."
He half turned in the big chair to face his visitor, who now was standing before the fireplace staring down at him.
"One day last month," he resumed, "I got out of my car in a big hurry at the top of the Haymarket. A fool on a motorcycle passed between the car and the sidewalk just as I stepped down, and I knew nothing further until I woke up in a drug store close by, feeling very dazed and with my coat in tatters and my left arm numbed from the elbow. A man was standing watching me, and presently when I had pulled round he gave me his card.
"He was Sir Charles Abingdon, who had been passing at the time of the accident. That was how I met him, and as there was nothing seriously wrong with me I saw him no more professionally. But he dined with me a week later and I had lunch at his club about a fortnight ago."
