"It was rather a public place," said the Saint. "But she's a nice girl and never goes out with the same man twice unless he's a millionaire. Or unless a millionaire asks her to. Which is why she was running around with young Kennet. Fairweather was the philanthropist who wanted him led back into the fold, and he was ready to buy a thousand-guinea fur coat to see it done. And Fairweather was the guy who arranged for him to come down for the week end. I got that much — and more."

The first taut-strung intensity of his manner was passing off, giving way before the slow return of the old exhilarant zest of battle which the other two knew so well. What was past was past; but the fight went on. And he was still in it. He began to feel the familiar tingle of impetuous vitality creeping again along his nerves; and the smoke came again through the first tentative glimmer of a Saintly smile.

"We were right, boys and girls," he said. "Our old friends the arms racketeers are on the warpath again: Luker, Fairweather and Sangore, just as we sorted them out, with Luker pulling the strings and Fairweather and Sangore playing ball. The Sons of France are in it, too, though I don't know how. But there's something big blowing up; and you can bet that whatever it is the arms manufacturers are going to end up in the money, even if a few million suckers do get killed in the process. Kennet had a bee about the arms racket; he'd been scratching around after them, and somehow or other he'd got on to something."

"What was it?" asked Patricia.

"I wish I knew. But we'll find out. It was something to do with papers and photographs. Lady Valerie didn't remember. She never paid any attention. The whole thing bored her. But it provides the one thing we didn't have before — the motive. Whatever it was, it was dynamite. It was big enough to mean that Kennet was too dangerous to be allowed to go on living. And he just wasn't smart enough or tough enough. They got him."

"Somehow," said Peter, "I can't see Fairweather doing a job like that."

"Maybe he didn't. Maybe Sangore didn't, either. But Kennet died — very conveniently. They knew about it. Probably Luker did it himself. I can just see him telling them — 'Leave it to me.' "

"He was taking a big risk."

"What risk? It would have been a cinch; except for the pure fluke that I happened to come along. You saw how the inquest went. There were a dozen ways he could have done it. Kennet could have been poisoned, or strangled, or had his throat cut or his skull cracked: almost anything short of chopping him up would have left damned little evidence on a body that had been through a fire like that. He could even have been just knocked out and locked in his room and left there for the fire to do the rest. We'll never know exactly how it was done, and we'll never be able to prove anything now; but I know that they murdered him. And I'm going to carry on from where Kennet left off. You can take your own choice, but I'm in this now — up to the neck."

They sat looking at him, and in their ears echoed the faint trumpets of the forlorn ventures in which they had followed him without question so many times before.
