As her father continued his inspection, Penny became a trifle bored. She sat down on the davenport and began idly to play with a toy lantern which had been dropped there. It was a child's toy such as one often saw in candy stores filled with sweets. The red isinglass had been broken in one place and the original string wick had been replaced by a tiny bit of cloth.
"Dad," said Penny presently, "do the Kirmenbachs have any children?"
"They didn't mention any," Mr. Nichols replied absently.
"They probably have grandchildren," Penny went on.
"Does it make any difference?" asked the detective. He was feeling irritated at his failure to find clues.
"Not particularly, Dad. I was just wondering about this toy lantern."
Mr. Nichols turned around and looked quickly at the object in her hand.
"Where did you get that?" he asked sharply.
"Why, it was right here on the davenport, Dad."
Mr. Nichols took the toy from her hand. Penny was surprised by the intent expression of his face as he examined the lantern.
