"How about Thelma Benton?" asked Perry Mason. "What was she doing?"
"She's got a complete alibi. She can account for every minute of her time."
"By the way," said Perry Mason, "what were you doing at that time, Sergeant?"
Sergeant Holcomb's voice showed surprise.
"Me?" he asked.
"Sure, you."
"Are you going to try and make me a suspect?" he asked.
"No," said Perry Mason. "I was just asking you what you were doing."
"I was on my way up to the office, here," said Sergeant Holcomb. "I was in an automobile, somewhere between the house and the office."
"How many witnesses can you bring to prove it?" asked Mason.
"Don't be funny," Sergeant Holcomb told him.
"If you'd use your noodle, you'd see that I'm not being funny," Mason remarked. "I'm serious as hell. How many witnesses can you bring to prove it?"
"None, of course. I can show when I was at my house, and I can show the time I arrived at the office."
"That's the point," said Mason.
"What is?" asked Sergeant Holcomb.
"The point that should make you suspicious about this perfect alibi of Thelma Benton's. Whenever a person can show an iron clad alibi covering what they've been doing every minute of the time, it's usually a sign that they've taken a great deal of care to perfect an alibi. A person who does that either participates in the commission of a murder and fakes an alibi, or else knows a murder is going to be committed, and therefore takes great pains to make a perfect alibi."
There was a long moment of silence. Then Sergeant Holcomb said, in a voice that was almost meditative, "So you think Thelma Benton knew Clinton Foley was going to be murdered?"
"I don't know anything at all about what Thelma Benton knew or didn't know," Perry Mason remarked. "I merely told you that a person who has a perfect alibi usually has a reason for it. In the ordinary run of a day's business, a person doesn't have an alibi for every minute of the time. He can't prove where he was, any more than you can prove it. I'll bet there isn't a man in the room who can prove, absolutely, by witnesses, what he was doing every minute between seventhirty and eight o'clock tonight."
"Well," Holcomb remarked wearily, "it's a cinch you can't."
"Sure," said Mason, "and if you weren't so dumb, that would be the best proof of my innocence, instead of an indication of my guilt."
"And you can't prove that you went to the house at eightthirty. There's no one who saw you go there; no one knows you had an appointment? No one who let you in? No one who saw you there at all at eightthirty?"
"Sure," said Perry Mason, "I can prove that."
"How?" asked Sergeant Holcomb.
"By the fact," Perry Mason said, "that I called police headquarters shortly after eightthirty and told them about the murder. That shows I was there at eightthirty."
"You know that isn't what I mean," Sergeant Holcomb told him. "I mean can you prove that you just came there at eightthirty?"
"Certainly not, we've already gone over that."
"I'll say we've gone over it," Sergeant Holcomb said. He scraped back his chair and got to his feet.
"You win, Mason," he said. "I'm going to let you go. You're pretty well established here in town, and we can put our finger on you whenever we want you. I don't mind telling you that I don't really think you did the murder, but I sure as hell think you're shielding some one, and that some one is a client of yours. I'm just going to tell you that in place of shielding your client, your conduct has made me all the more suspicious."
"Suppose you tell me just how," Mason said.
"I believe," said Sergeant Holcomb slowly, "that Arthur Cartright ran away with Foley's wife; that she told him a story of abuse, and that Cartright came back and shot Foley. Then I think that Cartright called you and told you what he'd done, and wanted to surrender himself; that you told him not to make a move until after you got there; that you went out and started Cartright going some place in a hurry, while you waited fifteen or twenty minutes, and then telephoned the police. In fact, there's no reason why you couldn't have been the one to have wiped off the dead man's face, and put the towel with the lather on it under the bathtub, near the dog chain."
"What's that make me? An accessory after the fact, or something of the sort?" asked Perry Mason.
"You're damn right it would," said Sergeant Holcomb, "and if I can ever prove it, I'm going to give you the works."
"I'm glad to hear you say so," said Perry Mason.
"Glad to hear me say what?" rasped Sergeant Holcomb.
"That you're going to give me the works if you can prove it. The way you've been acting, I thought you intended to give me the works whether you could prove any thing or not."
Sergeant Holcomb gestured wearily. "Go ahead," he said, "and get out of here. Hold yourself in readiness so we can get you for further questioning, if we want to."
"All right," Perry Mason said, "if that's the way you feel about it, and if the interview's over, switch out this damned light. I've got a headache from it now."
