A year and a half before this story opens Gavon Keith had got his captaincy in the North Essex Light Infantry, and just about the same time he found himself in a serious scrape. In a moment of weakness he had put himself absolutely in the power of Major Strause. Major Strause was his senior officer. There was a young subaltern in the regiment, of the name of Aylmer. Percy Aylmer had conceived a most chivalrous and passionate attachment for Keith. Keith had been good to him when he first joined, had put him up to the ropes, had been on every occasion his warm friend, and the young fellow in consequence gave the deepest devotion of his heart to Keith.

Now Percy Aylmer was second cousin to Major Strause. Both his parents were dead, and he was possessed of large private means. He had no near relations, and often boasted that he could do exactly what he liked with the thousands which belonged to him. Major Strause was always more or less in money difficulties. He was a man who both gambled and drank. His character in the regiment was by no means without reproach. It was whispered that he was quite capable of doing shady actions, and although nothing absolutely to his discredit was known, he inspired little trust, and had few friends. From the moment that Aylmer had joined the North Essex Light Infantry it had been Major Strause's intention to make use of him. His young cousin's money would help him out of his many difficulties. He intended to make use of it, and probably would have done so but for the influence of Gavon Keith. Keith, upright himself, scrupulously honourable, straight as a die in all his words and actions, read through the major, and in his own way counteracted the influence which he tried to exert over Percy Aylmer. Without saying much, Keith contrived that Aylmer should look at Strause somewhat with his own eyes. And the consequence was that on many occasions Strause's endeavours to get large sums of money from his kinsman were foiled.

There came a day when Aylmer hastily appeared in Keith's quarters, flung himself into a chair, and said,—

"Now what's to be done? Strause is evidently up a tree. He wants me to lend him five thousand pounds. I have all but promised, but as you have always been my best friend, I thought I would let you know."

Keith looked annoyed.

"Where is the use of talking?" he said. "You are aware of my opinion. Strause is a confirmed gambler. Whatever you let him have he will lose either on the turf or the Stock Exchange."

Keith had never said as much before, and he bit his lips with annoyance when the words had passed them.

"Do you really think as badly of him as that?" asked Aylmer, in an anxious tone.

"Yes," said Keith stoutly. "As I have spoken, I hold to it; I cannot mince matters. Strause is not an honourable man, and the less you, my dear boy, have to do with him the better. By-the-way, Aylmer, how old are you?"
