The shampoo

With a fire extinguisher, Shane said. He kept it in his car, see, and he had it in his hand. He was real fussy about fire always. Would never let anyone smoke anywhere near the stables. That Nigel . . . the sneer came back temporarily . . . the lads all smoked in the feed room, I ask you, behind his back. He'd no idea what went on.
Fire extinguisher . . . Wyfold spoke doubtfully, shaking his head.
Yeah, it was. It was. One of them red things about this long. Shane anxiously held up his hands about fifteen inches apart. With the nozzle, sort of, at the top. He was holding it by that, sort of swinging it. Ginnie was lying flat on the ground, face down, like, and I said, 'What have you gone and done?' and he said she'd been listening.
Wyfold sniffed.
It was like that, straight up, Shane said urgently.
Listening to what?
We were talking about the stuff, see.
. . .
Yeah. He seemed only briefly to feel the slightest alarm at the mention of it. I told him, see, that the stuff had really worked because there'd been a foal born that morning with half a leg, that Nigel he tried to hush it up but by afternoon he was half cut and he told one of the lads so we all knew. So I told Mr. Jackson and he said great, because it was time we'd heard, and there hadn't been a murmur in the papers and he was getting worried he hadn't got the dose right, or something. So anyway when I told him about the foal with half a leg he laughed, see, he was so pleased, and he said this was probably the last lot I'd have to do, just do the six bottles he'd brought, and then scarper.
