"We are wandering from the point."
"Quite so. Are you going to get your guv'nor down?"
"Look here. Have you got any money?"
"Well, I'm not absolutely stony."
"Then lend me two quid and I'll go home for a week-end and bring him back."
Darwen fished out his purse with a smile. "The seeds of wisdom are in you, I perceive," he said.
Suddenly the strains of music were wafted in to them through the open window. "What in thunder is that?" Darwen asked, getting up with a puzzled look and gazing out into the street. "By Jove, it's a kid with a mouth organ, looks like a gipsy kid."
With a serious face Carstairs got up and looked out of the window too. The boy was looking directly up at the window; as soon as he caught sight of Carstairs, he changed his tune abruptly.
"What's that tune, Darwen? I seem to know it."
"That's 'The Gipsy's Warning.' The kid plays very well, too, for an instrument like that. I thought it was a violin for a minute."
