Perry Mason's fingers drummed on the edge of his desk. His eyes, steady in their cold concentration, rested on Paul Drake's face. "Your man picked them up at the railroad depot, Paul?"
"Yes. He found them about ten minutes before train time. He took the same train they did, wired me from a suburban stop. I got busy on the telephone and had operatives board the train at different points to give him reinforcements. We've kept the pair in sight ever since they started."
"I want them kept on the run," Mason said.
"That's what Della Street told me. I wasn't certain I got the message straight. I wanted to find out just what it was you wanted."
Mason said slowly, "I want them hounded, I want them frightened, I want them kept on the move. Every time they go to a place and register under assumed names, I want those names. I want photographic copies of the hotel register."
"You want them to know that detectives are on their trail?"
"Yes, but I want it done cleverly. I don't want them to think detectives are too close on their trail. I want them to think detectives are just blundering around, covering the various hotels with descriptions and that sort of stuff."
The detective smoked silently for several seconds, then blurted out, "I think you're crazy, Perry!"
"Why?"
"It's none of my business," Drake said slowly, "but this man, Pender, must have been on the scene at the time of the murder. He telephoned his sister and admitted that he rang the doorbell of Moxley's apartment at around quarter past two in the morning. He had a motive for killing Moxley. He had undoubtedly been threatening Moxley. Now, if, instead of getting this man on the run, you should have him arrested and turn the newspaper boys on him, he'd make a lot of favorable publicity for Rhoda Montaine."
"Then what?" Mason asked.
"Then the district attorney would be in a spot. You could demand that Pender be arrested. You could demand that the district attorney call him as a witness."
"Then what?"
"Why then," Drake said, "you'd have him before the jury and you could rip him to pieces. You could show that he came here to get money out of Moxley; that he did it by making threats. You could make him either admit that he was on the scene of the murder at about the time it happened, or else you could impeach him by showing the conversation he had with his sister. You could show the way he treated my operative."
Mason smiled. "Yes," he said, "I could do all those things. For a while I'd be sitting pretty. Then we'd go to trial. The D.A. would put Pender on the witness stand, let Pender admit that he called up Moxley and tried to get money out of Moxley, let him admit, if necessary, that he made threats to Moxley. Then he would have Pender testify that he went to Moxley's apartment sometime after two o'clock in the morning, that Moxley had told him he was going to meet Rhoda Montaine at two o'clock and that she would have money for him. Pender went to collect the money. That's only natural. And Pender would testify that he stood in front of the street door which opened on Moxley's stairway and rang the bell repeatedly and didn't get any answer.
"That would tie in with the testimony of the witnesses who lived in the other apartment house, and by the time Rhoda Montaine got on the witness stand and tried to swear that she was the one who was ringing the bell while the murder was being committed, the jury would put her down for a liar. Then the district attorney would start dangling that garage key in front of the jury, and Rhoda Montaine would draw a verdict of firstdegree murder."
Drake nodded thoughtfully. "But," he said, "what's the idea of keeping those people on the run?"
"Sooner or later," Mason said, "the district attorney is going to realize the really vital point in this case. Some one was standing in front of the street door of Moxley's apartment ringing the bell, at the very moment the murder was committed. The testimony of the prosecution's main witnesses will establish that. Now, whoever that person was, he or she must be innocent of the murder, because, obviously, a person can't ring a doorbell on a street door and, at the same time, club a man over the head in an apartment on an upper floor and in the back of the house. On the other hand, the person who was ringing that doorbell isn't going to be anxious to come forward and admit being in the vicinity of the murder at the time it was committed, but when he is once run to earth by the district attorney, he's going to tell his story eagerly enough. Therefore, we have two people who are going to fight over that doorbell. One of them will be the person who actually was standing in front of the door, ringing the doorbell, and the other person will be the one who was murdering Moxley at the time the doorbell was ringing. Both of these people will insist that they were the ones who rang the doorbell.
"Rhoda Montaine has been the first one to advance her claim. It is weakened very materially by the presence of her garage keys in Moxley's apartment, but the jury may believe her, just the same. If, however, the district attorney can find some one who will go on the stand and swear positively that he was the one who was ringing the doorbell, it is going to weaken Rhoda Montaine's case."
Drake nodded. "If," Mason went on, "the district attorney gets hold of Pender, and Pender tells him his story, the district attorney will make him a star witness for the prosecution. I'll have to crossexamine him and try to prove to the jury that he is the murderer instead of the one who was really ringing the doorbell. Obviously, if I'm forced to crossexamine this man along the usual lines of simply trying to prove he's lying, I'm not going to get very far. The district attorney will have coached him and coached him carefully. But, if I can crossexamine him by proving to the jury that he fled over the country, using different aliases, leaving places in the dead of night, slinking about the country from city to city as a common criminal, I can brand his testimony as a lie. Now, that's what I'm doing with Oscar Pender, and, incidentally, with his sister. I'm giving them an opportunity to impeach themselves before a jury. The more places that they go to and leave hurriedly, the more different names they take, the more attempts they make to disguise themselves and to conceal themselves, the more the jury is going to believe that they are the guilty ones. That's more particularly true because Pender will probably forget some of the places he went to and some of the names he used. If I can produce hotel registers to impeach his testimony, I can rip him wide open."
"Then," Drake said, "you intend to let the district attorney discover Oscar Pender eventually."
"At the proper moment," Perry Mason said, "I may let the district attorney get hold of Oscar Pender, but I want to have it in my power to produce him, or not to produce him, just as I see fit."
Drake nodded his head, said slowly, "You say there will be two people who will claim to have been on the scene of the murder, ringing that doorbell. One of them will be the murderer. The other one will be the one who was actually ringing the doorbell. We now have found these two people. One of them is Oscar Pender; the other one is Rhoda Montaine. Therefore, one of these people must be guilty of the murder."
A slow smile twisted Perry Mason's countenance. "Excellent reasoning, Paul," he said, "only it happens that there are three people who claim to have rung that doorbell."
"Three?" the detective asked in surprise. "Who's the other one?"
"I can't tell you, Paul, I can only tell you that he's a person the district attorney knows about. So far, the district attorney hasn't been able to get any admissions from him because this man is trying to protect Rhoda. Sooner or later they'll drag his story from him. That's going to put Rhoda in an awful spot.
"The district attorney will bear down heavy on this doorbell business, and then is when I will produce Oscar Pender. Then is when I will show his guilty conduct. Then is when I will show his motive. Then is when I will mix the whole case up so badly the district attorney won't know what it's all about, and the jury will get so hopelessly confused they'll let the two men fight it out and acquit the woman."
Drake stared thoughtfully at the tip of his cigarette. He half turned and raised his eyes to the lawyer's countenance. "I've stumbled on to something else," he said.
"What?"
"Some one is looking for Pender."
"How do you know?"
"We've had men watching the place where Pender stayed and the apartment that his sister occupied, just in case some other accomplice should show up. Yesterday evening a bunch of detectives came down on the place like flies coming to a syrup jar. They swarmed all over the place and moved heaven and earth, trying to find where Pender and his sister were."
Mason's eyes showed interest. "Police detectives?" he asked.
"No, they were agency detectives, and, for some reason, they seemed anxious to keep their activities from coming to the attention of the police."
"There were lots of them, Paul?"
"I'll say. Some one certainly is spending money on the case."
Perry Mason's eyes narrowed. "C. Phillip Montaine," he said, "is a dangerous antagonist. I think he realizes something of what I have in mind. I don't know how he got on Pender's trail. Perhaps it was the same way you did, Paul."
Drake said slowly, "You think old man Montaine is working up this case independently of the district attorney's office?"
"I'm certain of it."
"Why?"
"Because he wants to keep Rhoda Montaine from being acquitted."
"Why?"
"Because, in the first place," Mason said slowly, "if she is acquitted, she'll be his son's legal wife, and I think we'll find C. Phillip Montaine has some very definite plans for his son's matrimonial future."
The detective stared incredulously at Perry Mason. "That doesn't seem a strong enough motive," he said, "to cause a man to try to get a woman convicted of murder."
Mason's lips twisted in a grin. "That, Paul, is what I thought at the time, when C. Phillip Montaine approached me with a proposition to pay me a handsome fee for representing Rhoda if I would consent to place her in a position where her defense would be materially weakened."
The detective gave a low whistle. After a moment of thoughtful silence, he said, "Perry, where do you suppose Oscar Pender really was at the time Gregory Moxley was being murdered?"
"There's just a chance," Mason said, "that he actually was standing in front of the street door, ringing the bell. That is one of the reasons why I would like to have enough ammunition in my hands when I crossexamine him to rip him wide open."
Drake's stare was steady. "You don't seem to have a great deal of faith in your client's innocence," he said.
Mason grinned, said nothing. Della Street opened the door, slipped into the room, glanced significantly at Paul Drake, and said to Perry Mason, "Mabel Strickland, Doctor Millsap's nurse, is in the outer office. She says she's got to see you at once. She's crying."
"Crying?" Mason asked.
Della Street nodded. "Her eyes are red and tears are streaming down her face. She can't stop them. She's crying so badly she can hardly see."
Mason frowned, jerked his head toward the corridor door.
Drake slid over the arm of the chair, got to his feet and said, "Be seeing you later, Perry."
When the door closed on the detective, Mason nodded to Della Street. "Show her in," he said.
Della Street opened the door, said, "Come in, Miss Strickland," then stood to one side so the lawyer could see the sobbing woman grope toward the doorway. Della Street piloted her into the office, guided her to a chair.
"What is it?" asked Perry Mason. The nurse tried to speak, but failed, holding a handkerchief to her nose. Perry Mason glanced at Della Street, who slipped unobtrusively from the office. "What's happened?" Mason inquired. "You can talk frankly to me. We're alone."
"You put Doctor Millsap on the spot," she sobbed.
"What happened to him?" Mason asked.
"He was kidnapped."
"Kidnapped?"
"Yes."
"Tell me about it," the lawyer said, his eyes wary and watchful.
"We had been working late at the office last night," she said, "almost until midnight. He was going to drive me home. We were driving along in the car when another car crowded us in to the curb. There were two men in it. I'd never seen either one of them before. They had guns. They told Doctor Millsap to get in the car with them and then they drove off."
"What kind of a car?" Mason asked.
"A Buick sedan."
"Did you get the license number?"
"No."
"What color was it?"
"Black."
"Did the men say anything to you?"
"No."
"Had they made any demands on you?"
"No."
"Did you report the affair to the police?"
"Yes."
"What happened?"
"The police came out and talked with me and went out to the place where our car had been stopped. They looked around but couldn't find anything. Then they made a report to headquarters, and then, apparently, the district attorney thought you had done it."
"Thought I had done what?" Mason asked.
"Grabbed Doctor Millsap so that he couldn't testify against your client at the trial."
"Was he going to testify against her?"
"I don't know anything about it. All I know is what the district attorney thought."
"How do you know what he thought?"
"Because of the questions he asked me."
"You were frightened?" asked Perry Mason.
"Yes, of course."
"What kind of a gun did the men have?"
"Automatics. Big black automatics."
Perry Mason got up from the desk, walked to the doors, made certain that they were closed, started pacing the office. "Look here," he said slowly, "Doctor Millsap didn't want to testify."
"Didn't he?"
"You know he didn't."
"Do I?"
"I think you do."
"Well, that's got nothing to do with his being kidnapped, has it?"
"I don't know," Perry Mason said thoughtfully. "I told him to take a sea trip for his health."
"But he couldn't. The district attorney served some papers on him."
Mason nodded. He strode up and down the office, watching the girl's quivering shoulders. Abruptly, he reached forward and snatched the handkerchief out of her hand. He raised it to his nostrils, took a deep inhalation.
She jumped to her feet, grabbed at his hand, missed it, clutched his arm, groped along the arm until she found his hand and tugged at the handkerchief. Mason held to the tearsodden bit of linen. She got one corner of it and tugged frantically. There was the sound of tearing cloth, and then a corner of the handkerchief ripped loose in her hands. Mason retained the biggest portion of the handkerchief.
The lawyer brushed the back of his hand across his eyes and laughed grimly. There were tears in his own eyes, tears that commenced to trickle down his cheeks. "So that's it, is it?" he said. "You dropped a little teargas into your handkerchief before you came into my office."
She said nothing. "Did you," Mason asked, staring at her with tearstreaked eyes, "drop some teargas in your handkerchief when you talked with the police?"
"I didn't have to then," she said, her voice catching in a sob, "they fffrightened me so that I didn't have to."
"Did the police fall for this story?" Mason inquired.
"I think so, because they thought the men might have been detectives you'd employed. They're tracing all of the Buick cars in the city to see if any of them are owned by detectives who might be working for Paul Drake."
Mason stood staring at her. "Damn this teargas," he said; "it blurs my eyes."
"I got an awful dose of it," she confided.
"Was there any automobile?" he asked.
"What do you mean?"
"Did any two men crowd you in to the curb in an automobile the way you said?"
"No. Doctor Millsap just went away. He wanted you to know that he wouldn't be a witness at the trial."
"If anything important develops," said Perry Mason, slowly, "could you reach him?"
"If anything important develops, you could telephone me," she said, "but be sure you talk plainly so I can recognize your voice, because otherwise I wouldn't believe it was you."
Perry Mason laughed, groped for a button on his desk and pressed it. Della slipped through the doorway from the outer office. "Della," said Perry Mason, "guide Mabel Strickland down to a taxicab."
Della Street gave a gasp. "My heavens, chief," she said, "you're crying!!!"
Perry Mason laughed. "It's contagious," he told her.
