It was still foggy when Mason was released from the room. A tall, raw-boned individual with a lazy drawl in his speech, a black sombrero on his head, and a manner of calm unhurried efficiency greeted Mason and said, "I'm the United States Marshal. What were you doing aboard the ship?"
"Visiting."
"Did you have business with Sam Grieb?"
"Yes."
"What was that business?"
"It was business I was handling for a client. I came aboard the ship to see Mr. Grieb. For all I know, he was dead when I got here. I didn't see him alive. I don't know who murdered him, and I'm not making any statement."
The marshal nodded and said, "You know I can take you before the grand jury and make you talk, don't you?"
Mason smiled and said, "You can take me before a grand jury. Whether you can make me talk is a matter of opinion. My personal idea is that you can't."
A slow smile of whimsical humor twisted the lips of the marshal. The sergeant who had been conducting the investigation said belligerently, "Well, we can hold you on suspicion of murder and stick you in a cell and..."
"I'm running this, Sergeant," the marshal interrupted. "That's all, Mr. Mason."
"When can I go ashore?" Mason asked.
"Any time," the marshal said.
"Did you find out anything?" Mason inquired.
The marshal merely smiled.
"Locate the woman in the silver gown?" Mason asked.
The marshal's smile became a grin. "Try reading the papers, Mr. Mason. You'll find a speed boat at the bottom of the landing-stage. Your coat and hat are over there on the table."
Mason struggled into the overcoat, turned up the collar, and silently walked along the hallway, through the deserted bar and casino to the deck.
There was virtually no motion to the ship. The fog had settled like a thick blanket. Moisture slimed the deck, the stairway, and the rope which served as a handhold. A speed boat was waiting at the foot of the landing-stage. Mason was the only passenger, and, so far as he could observe, save for the crew and the officers, no one remained aboard the gambling ship.
He took his seat near the stern of the speed boat, which immediately roared into motion. A moment later the hulk of the gambling ship was swallowed by the gray pall through which the speed boat roared on a compass course toward the shore.
The amusement pier was deserted when Mason landed. Contrary to his expectations, there were no newspaper reporters awaiting him. He found his car, climbed in it, and drove to his office building. He slid the car to a stop at the curb, entered the lobby and rang for the elevator. The night janitor brought up the cage, grinned at Mason, and said, "Pretty late for you to be working so hard, Mr. Mason. Your secretary's up in your office waiting for you."
Mason's face showed surprise. "Been there ever since around eleven o'clock," the janitor said.
Mason thanked him and signed the register while the elevator was shooting upward. His steps echoed down the deserted corridor. He turned a corner and saw lights in his office, transforming the frosted glass of the entrance doorway into a golden oblong, against which appeared in black letters:
PERRY MASON
ATTORNEY AT LAW
Entrance
Mason passed by the door to the entrance room and went to his private office. He opened the plain mahogany door with his key and saw Della Street tilted back in his big swivel chair, her feet propped upon the desk, ankles crossed. She was sound asleep.
She looked up as the latch clicked into place when the door closed. Her eyes, swollen with sleep, blinked in the bright light. "'Lo, Chief," she said sleepily. She lowered her feet from the desk, rubbed her eyes with her knuckles, grinned and said, "I fell asleep after the midnight news broadcast. That's the last one."
She indicated the portable radio which she had placed on the corner of Mason's desk, stretched her arms, yawned, made a little grimace, stamped her feet, and said, "Gosh, my legs have gone to sleep. What time is it?"
"Half past two," he told her. She tried to walk, but swayed on her numb feet. The lawyer caught her in his arms as she staggered. "Steady," he told her, holding her close to him.
She smiled sleepily and said, "I'm all pins and needles from my knees down. Gosh, I've been asleep a long time. That's one of the best sleeping chairs I ever sat in."
He slid an arm around her shoulders while she pillowed her cheek against his coat and closed her eyes.
"Why did you come up here?" he asked.
"There was a news flash on the ten o'clock broadcast that Sam Grieb had been murdered on his gambling ship and that everyone aboard was being held pending a complete investigation, so I thought you might want something, or try to get some message to me, and I figured I could work things better from here than from the apartment house where I hang out."
"Did anything else come in?" Mason asked.
She puckered her forehead into a frown and said, "Gee, Chief, those legs are driving me nuts. Let me walk around."
He circled her waist with his arm. Together, they started walking around the office, Della Street stamping her feet, making little grimaces of pain. "Let me see," she said... "There was some hot stuff in the midnight broadcast. It seems that Perry Mason, the noted attorney, was aboard the ship at the time of the murder, and was detained by authorities for questioning. The police are looking for a mysterious white-haired woman somewhere around fifty or fifty-five years of age, who wore a silver gown, silver slippers, a string of pearls about her neck and had snow-white hair cut in a boyish bob. Everyone described her appearance as striking... Tell me, Chief, why did Mrs. Benson go aboard? Were you to meet her out there?"
"No," he said, "she claims she went out to back me up in case I got into any trouble."
"Then she must have been carrying a gun," Della said.
"How are your legs?" the lawyer inquired.
"Better. I can feel the floor now, but we were talking about a gun. Look here, Chief, are you keeping something from me?"
"Lots of things," he told her.
She looked down at her legs and said, "Regretfully, Chief, I must inform you that my circulation is now restored."
He released her. She danced a swift jig step, perched herself on the corner of the office desk, and said, "Let's get this straight while we have a chance. The landlady out at my apartment house is absolutely okay. She's a friend of mine and perfectly swell. I told her I had some friends coming to see me and I didn't have room to put them up in my apartment, so I wanted to rent the adjoining apartment for a few days. You see, my apartment was once part of a double, but they made it into two singles, and the other single is vacant. I paid her a week's rent and then went out to your place and picked up a suitcase. Gee, Chief, I hope I got everything you need. I didn't have room to put in an extra suit of clothes, but I got socks, shirts, underwear, ties, shaving things, toothbrushes and pajamas. I also put in the pair of bedroom slippers that were under the edge of your bed... I thought you might want to hide out."
"What did you do with the suitcase?" he asked.
