The cab driver spun the cab about in a complete turn and pushed the motor into speed. Within a short time he had traversed the empty street and pulled up in front of the apartment house. Perry Mason ran through the lobby. This time the colored boy was staring at him with eyes that were filled with interest. Mason took the elevator to the third floor, opened the door of the apartment, switched on the light, closed the door behind him, turned the bolt into position so that the door could not be opened from the outside, and then started a swift search of the apartment. He did not look in the drawers of the builtin dresser, nor in the likely places, but prowled around in the dark corners of the closet. It took him but a matter of seconds to find a leather hat box thrust back into a corner of a closet shelf, with clothes piled in front of it so that the hat box was concealed.

Mason pulled out the hat box, snapped back the catch and pulled open the lid.

There was a woman's skirt, a pair of stockings and some white shoes in the hat box. They had been washed and were still damp. The moisture had soaked into the hat box, and it gave forth a steamy smell as the lid was pulled up.

The stockings showed no trace of stain, but there were one or two spots on the skirt which had not been removed, and the shoes showed unmistakable spots of brownish stain.

Perry Mason snapped the lid back on the hat box and left the apartment.

"Does you all live here?" the colored boy at the desk asked.

Perry Mason flipped a round silver dollar across the desk.

"No," he said, "I'm just taking a friend's apartment for the day."

"What's the number of it?" asked the colored boy.

"509," Perry Mason said, and pushed through the outer door of the lobby before there could be any further questions. He gave the hat box to the taxi driver.

"Take me back to the restaurant," he said. "Then go down to the Union Depot, buy a ticket to College City, check this hat box on the ticket, bring me back the ticket and the check, hand them to me where the young lady doesn't see them. Do you get that straight?"

The cab driver nodded.

Perry Mason passed him a twenty dollar bill.

"Step on it," he said.

Mason reentered the restaurant. Thelma Bell looked up from her plate of ham and eggs.

"Did you find it?" she asked.

He nodded.

"Fell out of my pocket," he said, "when I was sitting in the chair. It's a good thing I found it; it was lying right in plain sight. The officers would have picked it up and might have made some trouble because I'd have told them that I hadn't been to your apartment."

The waiter thrust his head through an arched hole in the partition which led to the kitchen and bellowed, "Put on those eggs and finish the ham."

Perry Mason sat down at the counter and stirred the coffee which the waiter placed in front of him.

"Was any one there?" she asked.

"No," he told her, "but they may be at any time."

"You seem to be pretty positive about that."

"I am."

"You know," she said, pausing with a piece of ham half way to her mouth, "no matter what happens, we have got to protect Margy."

Perry Mason said bluntly, "That's what I'm being paid for."

There was an interval of silence. The waiter brought Mason his ham and eggs. He wolfed them down and was finished by the time Thelma Bell was finished.

"All right, sister," he said, "we're going places."

"Can you tell me where?"

"Some place not too far away."

"I've got a couple of appointments tomorrow and the next day to do some modeling work."

"Ditch them."

"I haven't any money."

"You will have," he told her.

He finished the last of his coffee, wiped his lips with a napkin, looked across at her.

"Ready?" he asked.

"Ready," she said.

He took her arm and piloted her to the door of the restaurant. The cab drove up just as they emerged to the sidewalk.

"Here you are, boss," said the driver, holding out his hand palm down.

Perry Mason took the ticket and the check.

"What's that?" asked Thelma Bell suspiciously.

"An errand I had the cab driver do," he told her.

"Have you got enough change to cover the amount of the meter?" Mason asked the cab driver.

"I sure have, and then some," said the cab driver, and added audaciously, "enough to make a mighty nice little tip for me."

Mason stared intently at Thelma Bell.

"Can I trust you?" he asked.

"As long as it's for Margy, yes."

Mason pulled the railroad ticket the cab driver had given him from his vest pocket and handed it to her.

"Here's a oneway ticket to College City," he said. "Go there and register at a hotel. Register under your own name. You're going there to do some modeling work, if any one should start checking up on you tell them that and no more. If it gets serious, get in touch with me and don't say anything until I have given you instructions."

"You mean if the law should come?"

"Yes," he said, "if the law should come."

"Will there be trains running at this time of night?"

He looked at his watch.

"There's one leaves in twenty minutes," he said. "You can make it."

He handed the cab driver the suitcase and assisted Thelma Bell into the cab.

"Good night," he said, "and good luck. Ring up my office or send me a telegram. Leave word the name of the hotel where you're staying, and don't take a powder."

"A powder?" she asked.

"A runout powder," he told her. "I want you where I can put my hand on you."

She extended her hand and smiled at him.

"I'd do anything," she said, "for Margy."

Perry Mason took her hand. The fingertips were cold as ice. The cab driver climbed to the front seat.

"And you don't want me to tell any one about where I was? That is, about George Sanborne?"

Perry Mason shook his head with a fatherly smile.

"No," he said, "we'll save that as a surprise—a big surprise."

The cab motor roared into life. Perry Mason slammed the door, stood on the curb and watched the cab until the pale light rounded the corner. Then he went back to the restaurant.

"Telephone," he said.

The waiter indicated a pay telephone in a corner at the far end of the restaurant.

Perry Mason strode to it, dropped a coin and dialed the number of the Cooperative Investigating Bureau, and when he heard the voice of the operator, said, "Mason talking. Put on Mr. Samuels, if he's still there."

A moment later he heard the voice of Samuels booming with cordiality.

"Mason? We've done just what you wanted. We picked up that party, and she hasn't been out of our sight for a minute."

"Where is she now?" asked Mason.

"Ten minutes ago my men reported by telephone. She left Paul Drake's office about half an hour after you telephoned. She went to the Monmarte Hotel, where she has a room as Vera Cutter, of Detroit, Michigan, but she didn't give any street address when she registered. She took a room in the hotel early last evening. That is, around ninethirty some time, and here's something funny: her baggage is fairly new and has the initials E.L. on it. She's got a rather ornate handbag, with hammered silver in a monogram, and the monogram is E.L. Does that mean anything to you?"

"Not yet it doesn't," Perry Mason said, "but keep her shadowed."

"And you'll ring up for reports?"

"Yes. Be sure that you know who it is before you give out any information. Talk with me for a minute whenever I call, so that you know it isn't some one else using my name, and keep her shadowed every minute. I want to know everything about her. Better put on a couple of extra men, and if any one comes to the hotel to call on her, try and shadow them and find out all about them. Now, how about telephone calls? Can you arrange with the telephone operator at the Monmarte Hotel to let you listen in?"
