Yes, that was it; love of Life was the key to the mystery.
The zest of living was at its height for him; it knew but one menace - Death, the destroyer!
He turned out of the lighted thoroughfare. A narrow passageway, between high walls, offered a short cut to the Square where his house, famous for its art treasures, was situated.
The noise of the streets behind him lessened and faded, the soft thud of his own footsteps was the only sound to be heard.
And then out of the gloom in front of him came another sound.
Sitting against the wall was a man playing the flute.
One of the enormous tribe of street musicians, of course, but why had he chosen such a peculiar spot?
Surely at this time of night the police - Hamer's reflections were interrupted suddenly as he realized with a shock that the man had no legs.
A pair of crutches rested against the wall beside him.
Hamer saw now that it was not a flute he was playing but a strange instrument whose notes were much higher and clearer than those of a flute.
The man played on. He took no notice of Hamer's approach.
His head was flung far back on his shoulders, as though uplifted in the joy of his own music, and the notes poured out clearly and joyously, rising higher and higher...
It was a strange tune - strictly speaking, it was not a tune at all, but a single phrase, not unlike the slow turn given out by the violins of Rienzi, repeated again and again, passing from key to key, from harmony to harmony, but always rising and attaining each time to a greater and more boundless freedom.
It was unlike anything Hamer had ever heard.
There was something strange about it, something inspiring - and uplifting... it... He caught frantically with both hands to a projection in the wall beside him. He was conscious of one thing only - that he must keep down - at all costs he must keep down...
He suddenly realized that the music had stopped.
The legless man was reaching out for his crutches.
And here was he, Silas Hamer, clutching like a lunatic at a stone buttress, for the simple reason that he had had the utterly preposterous notion - absurd on the face of it! - that he was rising from the ground - that the music was carrying him upwards...
He laughed.
What a wholly mad idea!
Of course his feet had never left the earth for a moment, but what a strange hallucination!
The quick tap-tapping of wood on the pavement told him that the cripple was moving away. He looked after him until the man's figure was swallowed up in the gloom.
An odd fellow!
He proceeded on his way more slowly; he could not efface from his mind the memory of that strange, impossible sensation when the ground had failed beneath his feet...
And then on an impulse he turned and followed hurriedly in the direction the other had taken.
The man could not have gone far - he would soon overtake him.
He shouted as soon as he caught sight of the maimed figure swinging itself slowly along.
"Hi!
One minute."
The man stopped and stood motionless until Hamer came abreast of him.
A lamp burned just over his head and revealed every feature.
Silas Hamer caught his breath in involuntary surprise. The man possessed the most singularly beautiful head he had ever seen.
He might have been any age; assuredly he was not a boy, yet youth was the most predominant characteristic - youth and vigour in passionate intensity!
Hamer found an odd difficulty in beginning his conversation.
"Look here," he said awkwardly, "I want to know - what was that thing you were playing just now?"
The man smiled... With his smile the world seemed suddenly to leap into joyousness...
"It was an old tune - a very old tune...
Years old - centuries old."
He spoke with an odd purity and distinctness of enunciation, giving equal value to each syllable.
He was clearly not an Englishman, yet Hamer was puzzled as to his nationality.
"You're not English?
Where do you come from?"
Again the broad joyful smile.
"From over the sea, sir.
I came - a long time ago - a very long time ago."
"You must have had a bad accident.
Was it lately?"
"Some time now, sir."
"Rough luck to lose both legs."
"It was well," said the man very calmly. He turned his eyes with a strange solemnity on his interlocutor. "They were evil."
