I squeeze harder. He tries to pull away, but he hasn’t the strength.

“Nobody, I tell you!”

“You saw the killer.”

“That’s a goddamn lie!”

“Then who was it? Who else was there that night?”

Jones jerks his arm free and rubs his wrist. “You don’t know shit!”

“I’m going to blow this case wide open, my friend. And the longer you lie, the harder it’s going to go on you.”

He glances nervously at the showroom window. He actually looks like he wants to talk, but he has stuck with a lie for thirty years, and he won’t abandon it easily now. He grabs the key from the ignition, killing the engine. “Get out of this goddamn car.”

I start to get out, then stop. “You don’t mind if I call your wife to confirm that story, do you? About her calling you to go get groceries?”

“Do what you want. I divorced that bitch thirty years ago. Just get the hell out of this ride.”

I climb out and walk to my father’s car. The other salesmen are lined up against the showroom window, staring openly now. As Jones switches seats and pulls the Trans-Am toward the building, I start the BMW and drive quickly off the lot.

One cell phone call to my mother tells me all I need to know. Frank Jones’s ex-wife still lives in Natchez. After a messy divorce she married the president of a local oil company, quite a trade up from Frank Jones. The “messiness” involved affairs Jones had trailed with several secretaries at the battery plant. I dial the oilman’s home and ask for the ex-wife by her new name: Little.

“This is Mrs. Little,” says a rather prim voice.

“Mrs. Little, this is Penn Cage.”

“Dr. Cage’s boy?”

“That’s right. I—”

“I remember when you used to take the blood and X rays at your daddy’s office.”

At least she didn’t hang up. “Yes, ma’am. I wanted to ask you a couple of questions, if you don’t mind.”

“What about?”

“The day Del Payton died.”

A hesitation. “What about it?”

“I just talked to your ex-husband, and—”

“Sweet Jesus. What did that no-count say about me?”

Her anger sounds fresh, even after thirty years. “He used you for an alibi, Mrs. Little. He said he went out to the Triton parking lot on the night Del Payton died because you asked him to pick up some groceries.”

“That’s a damn lie, pardon my French. He was in that parking lot because he was diddling one of his floozies.”

This remarkable statement stops me for a moment. “Are you . . . you’re saying you think someone was in the lot with him that night?”

“Are you hard of hearing? That no-good tomcat came home that night and asked me to tell the police same story he told you. And I did, numbskull that I was.”
