Munn did not answer her. After a moment he asked, "Did you hear a scream this afternoon?"
"Yes," she answered.
"How long after the screaming did your son come in?"
She hesitated. What was the best answer to make? Bewildered, she tried to decide. "Ten minutes or so," she said.
"Just so," agreed Munn. "Brenner, when did you come in?"
A trace of Mart's sullenness rose in his face. "I told you that once," he said.
"I mean how long after Tobey?"
"I dunno," said Mart.
"How long, Mrs. Brenner?"
She hesitated again. She scented a trap. "Oh, 'bout ten to fifteen minutes, I guess," she said.
