These two men had not exchanged a word, had not even seen each other, save at the rarest intervals, for nearly a quarter of a century. They were the principals in a quarrel of the most vivid, satanic, and incurable sort known to anthropological science—the family quarrel—and the existence of this feud was a proof of the indisputable truth that it sometimes takes less than two to make a quarrel. For, though Owen Hugo was not absolutely an angel, Ravengar had made it single-handed.

The circumstances of its origin were quite simple. When Louis Ravengar was nine years old, his father, a widower, married a widow with one child, aged six. That child was Hugo. The two lads, violently different in temperament—the one gloomy and secretive, the other buoyant and frank—with no tie of blood or of affection, were forced by destiny to grow up together in the same house, and by their parents even to sleep in the same room. They were never apart, and they loathed each other. Louis regarded young Owen as an interloper, and acted towards him as boys and tigers will towards interlopers weaker than themselves. The mischief was that Owen, in course of years, became a great favourite with his step-father. This roused Louis to a fury which was the more dangerous in that Owen had begun to overtake him in strength, and the fury could, therefore, find no outlet. Then Owen's mother died, and Ravengar, senior, married again—a girl this time, who soon discovered that the household in which she had planted herself was far too bellicose to be comfortable. She abandoned her husband, and sought consolation and sympathy with another widower, who also was blessed with offspring. Such is the foolishness of women. You cannot cure a woman of being one. But it must be said in favour of the third Mrs. Ravengar and her consoler that they conducted their affair with praiseworthy attention to outward decency. She went to America by one steamer, and purchased a divorce in Iowa for two hundred dollars. He followed in the next steamer, and they were duly united in Minneapolis. Meanwhile, the Ravengar household, left to the ungoverned passions of three males, became more and more impossible, and at length old Ravengar expired. In his will he stated that it was only from a stern sense of justice that he divided his considerable fortune in equal shares between Louis and Owen. Had he consulted his inclination, he would have left one shilling to Louis, and the remainder to Owen, who alone had been a true son to him.

It was a too talkative will. Testators, like politicians, should never explain.

Louis, who got as a favour half the fortune of which the whole was, in his opinion, his by right, was naturally exasperated in the highest degree by the terms of the indiscreet testament, and on the day of the funeral he parted from the son of his step-mother, swearing, in a somewhat melodramatic manner, that he would be revenged. Hugo was then twenty-one, and for twenty-five years he had waited in vain for symptoms of the revenge.

And now they met again, in the truest sense strangers. And each had a reason for humouring the other, for each wanted to know what the other had to do with Camilla Payne.

'So you're determined, Louis,' said Hugo lightly, 'to bring me to my knees about the transfer of my business to a limited company, eh?'

'What on earth do you mean, man?' asked Ravengar, whose voice was always gruff.

'I refer to Polycarp's visit yesterday.'

'I know nothing of it,' said Ravengar slowly, looking across the wilderness of roofs.

'Then why are you here, Louis? Is your revenge at last matured?'
