The dust rose in douds behind it. Then it was airborne. I watched it lift slowly into the gusty air and fade off into the naked blue sky to the southeast.

Then I left. Nobody at the border gate looked at me as if my face meant as much as the hands on a dock.

It's a long drag back from Tijuana and one of the dullest drives in the state. Tijuana is nothing; all they want there is the buck. The kid who sidles over to your car and looks at you with big wistful eyes and says, "One dime, please, mister," will try to sell you his sister in the next sentence. Tijuana is not Mexico. No border town is anything but a border town, just as no waterfront is anything but a waterfront. San Diego? One of the most beautiful harbors in the world and nothing in it but navy and a few fishing boats. At night it is fairyland. The swell is as gentle as an old lady singing hymns. But Marlowe has to get home and count the spoons.

The road north is as monotonous as a sailor's chantey. You go through a town, down a hill, along a stretch of beach, through a town, down a hill, along a stretch of beach.

It was two o'clock when I got back and they were waiting for me in a dark sedan with no police tags, no red light, only the double antenna, and not only police cars have those. I was halfway up the steps before they came out of it and yelled at me, the usual couple in the usual suits, with the usual stony leisure of movement, as if the world was waiting hushed and silent for them to tell it what to do.

"Your name Marlowe? We want to talk to you."

He let me see the glint of a badge. For all I caught of it he might have been Pest Control. He was gray blond and looked sticky. His partner was tall, good-looking, neat, and had a precise nastiness about him, a goon with an education. They had watching and waiting eyes, patient and careful eyes, cool disdainful eyes, cops' eyes. They get them at the passing-out parade at the police school.

"Sergeant Green, Central Homicide. This is Detective Dayton."

I went on up and unlocked the door. You don't shake hands with big city cops. That close is too dose.

They sat in the living room. I opened the windows and the breeze whispered. Green did the talking.

"Man named Terry Lennox. Know him, huh?"

"We have a drink together once in a while. He lives in Encino, married money. I've never been where he lives."

"Once in a while," Green said. "How often would that be?"

"It's a vague expression. I meant it that way. It could be once a week or once in two months."

"Met his wife?"

"Once, very briefly, before they were married."

"You saw him last when and where?"

I took a pipe off the end table and filled it. Green leaned forward dose to me. The tall lad sat farther back holding a ballpoint poised over a red-edged pad.

"This is where I say, 'What's this all about?' and you say, 'We ask the questions.'"

"So you just answer them, huh?"

I lit the pipe. The tobacco was a little too moist. It took me some time to light it properly and three matches.

"I got thne," Green said, "but I already used up a lot of it waiting around. So snap it up, mister. We know who you are, And you know we ain't here to work up an appetite."

"I was just thinking," I said. "We used to go to Victor's fairly often, and not so often to The Green Lantern and The Bull and Bear-that's the place down at the end of the Strip that tries to look like an English inn-"

"Quit stalling."

"Who's dead?" I asked. Detective Dayton spoke up. He had a hard, mature, don't-try-to-fool-with-me voice. "Just answer the questions, Marlowe. We are conducting a routine investigation. That's all you need to know."

Maybe I was tired and irritable. Maybe I felt a little guilty. I could learn to hate this guy without even knowing him. I could just look at him across the width of a cafeteria and want to kick his teeth in.

"Shove it, Jack," I said. "Keep that guff for the juvenile bureau. It's a horse laugh even to them."

Green chuckled. Nothing changed in Dayton 's face that you could put a finger on- but he suddenly looked ten years older and twenty years nastier. The breath going through his nose whistled faintly.

"He passed the bar examination," Green said. "You can't fool around with Dayton."

I got up slowly and went over to the bookshelves. I took down the bound copy of the California Penal Code. I held it out to Dayton.

"Would you kindly find me the section that says I have to answer the questions?"

He was holding himself very still. He was going to slug me and we both knew it. But he was going to wait for the break. Which meant that he didn't trust Green to back him up if he got out of line.

He said: "Every citizen has to co-operate with the police. In all ways, even by physical action, and especially by answering any questions of a non-incriminating nature the police think it necessary to ask." His voice saying this was hard and bright and smooth.

"It works out that way," I said. "Mostly by a process of direct or indirect intimidation. In law no such obligation exists. Nobody has to tell the police anything, any time, anywhere."

"Aw shut up," Green said impatiently. "You're crawfishing and you know it. Sit down. Lennox 's wife has been murdered. In a guest house at their place in Encino. Lennox has skipped out. Anyway he can't be found. So we're looking for a suspect in a murder case. That satisfy you?"

I threw the book in a chair and went back to the cpuch across the table from Green. "So why come to me?" I asked. "I've never been near the house. I told you that."

Green patted his thighs, up and down, up and down. He grinned at me quietly. Dayton was motionless in the chair. His eyes ate me.

"On account of your phone number was written on a pad in his room during the past twenty-four hours," Green said. "It's a date pad and yesterday was torn off but you could see the impression on today's page. We don't know when he called you up. We don't know where he went or why or when. But we got to ask, natch."

"Why in the guest house?" I asked, not expecting him to answer, but he did.

He blushed a little. "Seems she went there pretty often. At night. Had visitors. The help can see down through the trees where the lights show. Cars come and go, sometimes late, sometimes very late. Too much is enough, huh? Don't kid yourself. Lennox is our boy. He went down that way about one in the A.M. The butler happened to see. He come back alone, maybe twenty minutes later. After that nothing. The lights stayed on. This morning no Lennox. The butler goes down by the guest house. The dame is as naked as a mermaid on the bed and let me tell you he don't recognize her by her face. She practically ain't got one. Beat to pieces with a bronze statuette of a monkey."

"Terry Lennox wouldn't do anything like that," I said. "Sure she cheated on him. Old stuff. She always had. They'd been divorced and remarried. I don't suppose it made him happy but why should he go crazy over it now?"

"Nobody knows that answer," Green said patiently. "It happens all the time. Men and women both. A guy takes it and takes it and takes it. Then he don't. He probably don't know why himself, why at that particular instant he goes berserk. Only he does, and somebody's dead. So we got business to do. So we ask you one simple question. So quit horsing around or we take you in."

"He's not going to tell you, Sergeant," Dayton said acidly. "He read that law book. Like a lot of people that read a law book he thinks the law is in it."

"You make the notes," Green said, "and leave your brains alone. If you're real good we'll let you sing 'Mother Machree' at the police smoker."

"The hell with you, Sarge, if I may say so with proper respect for your rank."
