"After 3:30, when did you next see Callista Blake?"

"About quarter past four, getting into her Volkswagen."

"You didn't see her come out of that wild garden?"

"No, I didn't happen to. I think I'd gone indoors for a while."

"You're quite certain she went into the wild garden alone? The children couldn't have gone with her, or perhaps ahead of her?"

"No, they didn't. Shortly before 3:30 Doris Wayne—she's ten—started an argument with her younger brother Billy. Mrs. Wayne reproved them, told them to sit by the picnic table and restrain their voices. They did." Mrs. Jason glacially smiled. "The origin of the argument—"

"Well, that might lead us too far afield. Just—"

"If the Court please—" Cecil Warner cleared his throat with sudden but stately sonority—"I submit that, to appease the curiosity of all present including myself, the casus belli between Doris and William Wayne, though doubtless not part of the res gestae, should be made known." Cecil was even standing, making a production of it, announcing with eyebrows and twinkle that all he wanted was to have a bit of ponderous fun and relieve the tension: what could be more innocent?

Risky, but Mann wanted to play along. He said: "Mm, yes. The rules of evidence should not debar us from ascertaining the gravamen of this ancillary conflict." How'm I doing, Cecil? Gravamen, ancillary, each five dollars, please. Hunter looked uneasy, not prepared with any elephantine humor of his own.

"Well, your Honor, Callista had been showing Doris Wayne how to make a squeak by blowing across a grass-blade held between the thumbs. The effect on neighboring eardrums is impressive. The argument I mentioned arose when Billy wished to perfect himself in the same peculiar art and was informed by his sister that he was not old enough."
