The charity ball was in full swing when he walked inside the grand ballroom and stood unobtrusively behind a tall potted palm. The ballroom was spacious and majestic. The parquet dance floor was laid in an intricate sunburst design and colorful murals adorned the ceiling. He spied the mysterious woman, seated with her back to him, with three couples at table six. She appeared to be alone, without an escort. He sidled up to the hotel director in charge of the evening’s event.

“Pardon me,” said Bell with a friendly smile, “but could you tell me the name of the lady in the blue dress at table six?”

The director straightened with a haughty look. “I’m sorry, sir, but we frown on giving information on our guests. Besides, I can’t know everybody who comes to the ball.”

Bell passed him a ten-dollar gold certificate. “Will this jog your memory?”

Without a word, the director held up a thin leather book and ran his eyes over the entries. “The single lady at the table is Miss Rose Manteca, a very wealthy lady from Los Angeles whose family owns a vast ranch. That’s all I can tell you.”

Bell patted the director on the shoulder. “I’m grateful.”

The director grinned. “Good luck.”

An orchestra was playing a medley of ragtime and modern dance tunes. Couples were dancing to a song called “Won’t You Come Over to My House.”

Bell walked up behind Rose Manteca and whispered in her ear. “Would you please consent to dance with me, Miss Manteca?”

She turned from the table and looked up. Golden brown eyes looked into a pair of mesmeric violet eyes. She was smooth, Bell thought, but his sudden appearance in evening dress completely stunned her. She lowered her eyes and recovered quickly, but not before her face blushed red.

“Forgive me, Mr. Bell. I did not expect you so soon.”

“So soon?” he asked. What an odd thing to say, he thought.

She excused herself to the people at the table and stood up. Gently, he took her by the arm and led her to the dance floor. He slipped his arm around her narrow waist, took her hand, and stepped off smartly with the music.

“You’re a very good dancer,” she said after he swept her around the floor.

“Comes from all those years my mother forced me to take lessons so I could impress the debutantes in our city.”

“You also dress very well for a detective.”

“I grew up in a city where the affluent men lived in tuxedos.”

“That would be Boston, would it not?”

For once, in his years of investigation, Bell was at a loss, but he recovered and came back. “And you’re from Los Angeles.”

She was good, he thought. She didn’t bat an eye.

“You’re very knowledgeable,” she said, unable to fathom his eyes.

“Not half as knowledgeable as you. What is your interest? How do you know so much about me? Better yet, I should ask why?”

“I was under the impression you like to solve mysteries.” She tried consciously to look past him over his tall shoulder, but she was drawn into those incredible eyes. This was a sensation, a stirring she had not counted on.

The photographs she had been shown did not do him justice face-to-face. He was far more attractive that she had imagined. He also came off as highly intelligent. This she’d expected, though, and could understand why he was so famous for his intuition. It was as though he was stalking her as she was stalking him.

The music ended and they stood together on the dance floor waiting for the orchestra to begin the next musical arrangement. He stepped back and ran his eyes from her shoes to the top of her beautifully styled hair. “You are a very lovely lady. What prompted your interest in me?”

“You’re an attractive man. I wanted to know you better.”

“You knew my name and where I came from before you met me in the elevator. Our meeting was obviously premeditated.”

Before she could reply, the orchestra began playing “In the Shade of the Old Apple Tree,” and Bell led her around the floor in a foxtrot. He held her against him and gripped her hand tightly in his. Her waist was small, made even smaller by a corset. The top of her head came up even with his chin. He was tempted to press his lips against hers but thought better of it. This was neither the time nor the place. Nor were his thoughts on romance. She was spying on him. That was a given. His mind was trying to formulate a motive. What interest could a total stranger have in him? The only possibilities he could conjure up were that she’d been hired by one of the many criminals he had put behind bars, shot, or seen hanged. A relative or friend out for revenge? She didn’t fit the image of someone who associated with the scum he had apprehended over the last ten years.

The music ended, and she released his hand and stood back. “You’ll have to excuse me, Mr. Bell, but I must return to my friends.”

“Can we meet again?” he asked with a warm smile.

She slightly shook her head. “I don’t think so.”

He ignored her negative reply. “Have dinner with me tomorrow night.”

“Sorry, I’m busy,” she answered, with a haughtiness in her voice. “And even in your fancy tuxedo you couldn’t bluff your way into the Western Bankers’ Ball at the Denver Country Club like you did tonight at the benefit for St. John’s Orphans.” Then she threw out her chin, swept up her long skirt, and walked back to her table.

Once seated, she stole a glance back at Bell, but he was nowhere to be seen among the crowd. He had completely disappeared.

THE FOLLOWING MORNING, BELL WAS THE FIRST ONE in the office, using a skeleton key that could open ninety doors out of a hundred. He was sorting through bank robbery reports at the end of the long table when Arthur Curtis and Glenn Irvine entered the conference room. Bell rose to greet them and shook hands. “Art, Glenn, good to see you both again.”

Curtis stood short and rotund, with a rounded stomach neatly encased in a vest whose buttons were stretched to their limit. He had thinning sandy hair, wide megaphone ears, blue eyes, and a smile that showed a maze of teeth that lit up the room. “We haven’t seen you since we tracked down Big Foot Cussler after he robbed that bank in Golden.”

Irvine placed his hat on a coat stand, revealing a thick head of uncombed brown hair. “As I remember,” he said, standing as tall and as scrawny as a scarecrow, “you led us directly to the cave where he was hiding out.”

“A simple matter of deduction,” Bell said with a tight smile. “I asked a pair of young boys if they knew of a place where they liked to hide out from their folks for a few days. The cave was the only location within twenty miles, close enough to town so Cussler could sneak in for supplies.”
