Mason said, “This is your first murder case. I’ve seen dozens of them. I don’t know very much about Miss Sunley. I’ve seen enough to know that you’re trying to protect her. Perhaps it hasn’t occurred to you that the most certain way to turn the limelight of pitiless, hostile publicity on her would be to twist the truth to try to keep her out of it.”

Arthur Gentrie was interested despite himself. “I don’t get you,” he said.

“You start suppressing or distorting facts to keep Opal Sunley out of that case,” Mason said, “and you’ll find that you’ve not only dragged her in, but have painted her with a crimson brush doing it.”

“What’s that crimson-brush crack?” Arthur Gentrie asked, suddenly belligerent.

Mason said, “Nice young men don’t tell lies in murder cases for nice young women. Do you get me?”

“I’m not certain that I do.”

“You make a good impression. The public would look on you as a nice young man. They would consider that the motivation which would cause you to lie to protect a woman would have to be more powerful and more compelling and, frankly, a little more sinister than the ordinary attraction which a nice young woman would or should have for you.

“Now, I’m not going to argue with you. I’m not going to plead with you. I’ve told you facts. If you want to drag Opal Sunley into this thing, if you want to smear her reputation, if you want the newspapers to treat her as an older woman who was leading a young boy around by the nose...”

Gentrie came up out of the chair as though he had been a fighter springing for an antagonist at the sound of the gong. “No, you don’t,” he shouted. “You can’t...”

Mason held up his hand, palm outward. Aside from that, he made no move. “Hurts, doesn’t it?” he said. “It hurts because you know it’s the truth. Now, what have you to tell me?”
