"I hope I haven't kept you waiting," remarked the detective pleasantly.

"No, I arrived only a few minutes ago. May I talk with you?"

"Certainly," replied Mr. Nichols. He turned toward the housekeeper who was loitering in the doorway. "That will be all, Mrs. Masterbrook."

After the woman had gone, Mr. Nichols offered the visitor a chair on the porch. Penny started to go into the house but Mr. Madden indicated that it was unnecessary for her to leave.

"My business isn't of a confidential nature," he said pleasantly. "In fact, I am trying to broadcast my mission here in Kendon."

"If I had known that I should have invited our housekeeper to remain,"

smiled Mr. Nichols. "The town has few secrets unshared by her."

"I came here in search of my business partner, a man by the name of Jay Kline," the visitor went on. "He left Chicago some days ago, coming to Kendon to attend to a private business matter which did not concern the firm. He has not been heard from since."

"Indeed?" inquired Mr. Nichols politely. "You think that he has met with a mishap?"

"Yes, that is my belief," returned Mr. Madden gravely. "Mr. Kline gave me to understand that his mission here was a dangerous one. If something had not gone wrong I know I should have heard of him before this."

"Whom did your friend plan to visit here?"

"I don't know," the visitor admitted. "Mr. Kline was very secretive."

"Have you inquired for him in the village?"

"Yes, no one has heard of the man. It is all very bewildering."

"Are you actually sure that he came to Kendon?" inquired Mr. Nichols.

"I have no proof, but neither have I any reason for thinking that he would go elsewhere. I am convinced that my partner met with foul play."

"You wished to consult me professionally?" Mr. Nichols asked. He wondered who had sent the man to him.

"Professionally?" Mr. Madden questioned in a puzzled tone.

"I am a detective, you know," Mr. Nichols smiled. "On vacation at the present."

"Oh," murmured the visitor in surprise. "No, I wasn't aware of your calling. The grocery store man sent me to you. He told me that you had picked up a stranger in your car several nights ago, and I thought that by some chance the man might have been my missing partner."

"We did give a young man a lift to town," Mr. Nichols said. "But his name was Walter Crocker."

"Then I'll not trouble you further," said the visitor, arising. "Thank you for your time."

He bowed to Penny and her father and drove away in his car.

"He was afraid to tell me any more about the case for fear I'd charge him a fee," chuckled Mr. Nichols. "Very likely by the time Mr. Madden gets back to Chicago his partner will be there too."

"Dad," said Penny thoughtfully, "maybe the man we picked up really was Jay Kline."

"What was that?" Mr. Nichols demanded.

"I said, perhaps the fellow who rode to town with us wasn't Walter Crocker at all but merely told us that name--"

"I can't keep up with your theories," Mr. Nichols laughed. "You have a new one every minute."

"That's because there are so many new developments, Dad. I wonder if it's too late to stop Mr. Madden?"

"He's a mile down the road by this time. And I'm glad of it because I don't want you to make yourself or me look ridiculous. What gave you the idea that Jay Kline and Walter Crocker are one and the same person?"

"I don't know," admitted Penny. "It just came to me all at once.

Walter Crocker mysteriously disappeared--"

"You mean he went back to the city."

"We don't know that at all," Penny argued. "Did anyone except you and me see Walter Crocker? No! He went to talk with his uncle, Herman Crocker, and was seen no more. His automobile mysteriously appears in Crocker's barn--"

"Not so loud!" Mr. Nichols warned. "I think Mrs. Masterbrook is standing by the dining room door."

Penny subsided into hurt silence. She felt that her theories were logical and she did not like to have her father tease her.

"Well, anyway I didn't think up the toy lantern clue!" she muttered under her breath.

"That reminds me, I must telephone Inspector Harris," said Mr. Nichols.

"I hope he thinks more of my theory than you do."

Penny could tell that her father was growing deeply interested in the Kirmenbach robbery case and following his talk with Inspector Harris, he admitted that he had promised to do further work.

"It's likely to be a tough case," he told Penny the next morning.

"Harris thinks we'll have no luck in tracing the toy lantern. I'm driving over to the Kirmenbach place again this morning."

"I believe I'll stay here this time," she replied.

Penny was glad that she elected to remain, for a short time after her father left, Herman Crocker drove into the yard. He greeted her in a more cordial tone than usual.

"Is everything all right here?" he asked.

"Oh, yes, we're getting along very well," Penny answered, glancing shrewdly at the old man. She felt certain that his real purpose in coming to the cottage was not to inquire for their comfort.

"Mrs. Masterbrook at home?" Mr. Crocker questioned casually.

"I saw her walking down toward the road a few minutes ago. Shall I call her?"

"No, I didn't want to see her anyway," he answered quickly. "Just thought I'd take a look around. I have some things stored up in the attic that I'd like to get."

"Just go right in," said Penny. She fell into step with him. "Oh, by the way, do you know Michael Haymond, our new hired man?"

"Never heard of him."

"I thought he might have been to see you."
