"Taylor"s has several hundred employees to whom charge plates have been issued."
"You must have a record of every one," Nancy reminded him.
"We have. But the number of this plate has been obliterated. I couldn"t interview all our workers on such slim evidence."
"I know how the checkup could be made without very much work," Nancy said.
"How?"
"By elimination. Ask all your employees to turn in their plates on a pretext of changing them. Naturally the person who lost this one wouldn"t be able to."
Mr. Johnson considered the suggestion.
"You present your case very well, Miss Drew." He smiled. "I"ll do it, even though it does inconvenience us."
Satisfied, Nancy next called at her father"s office. He promptly put aside his work.
"Nothing new to report. Mr. Lightner came in to see me this morning. He"s still worried about those threatened lawsuits. We"re stalling for time. And what"s your news?"
Nancy told him, then said she was going to follow Tombar that noon.
"At a safe distance," Mr. Drew cautioned. "And tell me, what do you hope to find out?"
Nancy explained about seeing Tombar bring a package from the entertainment company the same day the telltale cloak disappeared.
"He shook me off his trail rather pointedly when I followed him," she said. "And he"s perfectly horrid about Linda without any reason. Maybe he"s afraid she"ll find out something."
"Better keep your suspicions to yourself until you have some evidence to back them up."
"I promise, Dad."
Nancy phoned Linda Seeley, who told her that Mr. Tombar had not come in that day.
"And the mysterious torn black cloak has never been returned," Linda reported. "But I have something else to tell you," she said. "Come over at lunchtime, will you?"
At noon the two girls met at a soda counter and sat down side by side. Linda said that everything was going well at the office.
"But I suppose something could happen at any time. Nancy, how would you like to attend a musicale?"
"When?"
"Tomorrow afternoon. At the Elkin home on Kenwood Boulevard. The affair will be very plush. It"s to introduce the French singer Madame De Velleaux."
"Is your company in charge?"
"Yes, and Mr. Lightner says he"ll get you an invitation if you"re interested. I"ll be there."
Nancy decided instantly. She would enjoy the concert and there was the possibility that one of the party thieves might put in an appearance. Tomorrow would be the twenty-first of June, and 621 was one of the dates in the hood.
"Where shall I meet you, Linda?"
"I may have to go early," the other replied. "Tell you what! I"ll send your invitation by messenger. Then if I"m held up, you won"t be kept waiting at the door."
The next day, upon reaching the Elkin home, Nancy presented her invitation to the butler at the front entrance. The hall and living room were richly furnished and held many priceless art objects. She went upstairs and laid her light coat on one of the beds. As far as Nancy could observe, there was not a single plainclothesman on duty.
She went downstairs and lingered near the front door so that she could scrutinize all new arrivals. A few minutes later Nancy caught sight of Peter Tombar. He saw her at the same moment and came over.
"Well, well," he said with false geniality, "so you"re an admirer of Madame De Velleaux?"
"I"ve never heard her sing," Nancy replied. "Is Linda Seeley here?"
"Linda isn"t coming," he said shortly.
"Is she ill?"
"No. She was needed elsewhere. I sent her to another house. I"m taking over here myself."
Nancy remained silent, wondering whether the excuse he had given was really what lay behind Linda"s failure to appear.
"How did you get in?" Tombar asked Nancy abruptly.
"By invitation."
"And where did you get the invitation?" the man growled. "Your name wasn"t on the guest list."
Nancy smiled sweetly. "Perhaps you didn"t look carefully enough."
Deciding not to give the man an opportunity to question her further, Nancy sauntered away. She entered the music room and seated herself in the last row near the door. A few minutes later the concert began.
After sitting there long enough to make it appear that she had come only to hear the singer, Nancy left to start her sleuthing. She tiptoed out and stood in the main hall a moment. The other rooms on the lower floor appeared to be deserted. Meeting one of the maids, she asked her if she knew what had become of the man from the Lightner Entertainment Company.
"No, miss, I don"t," the maid replied. "I"ve been upstairs. The only person up there is the sick lady."
"Someone ill?"
"Yes, miss. One of the guests. Just a few minutes ago she asked me to get her a cup of tea from the kitchen. I"m going for it now."
"Where is the lady?"
"In the bedroom where the guests left their coats."
The maid hastened to the kitchen. Nancy hesitated a moment, mulling over the information. Was the woman really ill? The errand might have been a way to get rid of the maid!
Silently Nancy mounted the stairway to the bedroom and opened the partly closed door. A slim woman stood at the dresser, hurriedly removing jewelry from the top drawer!
In the mirror Nancy caught a fleeting glimpse of a hard, brazen face. She knew instantly that she had seen the woman before. The Hendricks" ball perhaps? Yes, that was it! This was the woman who had worn the Javanese costume!
Now Nancy had caught her red-handed. She must bar the exit and call for help!
