“Yes, what’s going on? You had us frightened silly,” Iola joined in. “First Chet gets a threatening phone call, and then suddenly all three of you run out of the house like madmen!”

“Calm down, girls,” Frank said soothingly. “I saw a prowler, and we were looking for him, but all we found was this!” He tossed the gray wig onto a chair in the hall.

Suddenly there was a loud wail from Chet. “My Welsh rabbit! It’s been standing so long it will be ruined!”

Iola began to giggle. “Oh, you men!” she said. “Do you suppose Callie and I would let all that good cheese go to waste? We kept that Welsh rabbit at just the right temperature and it isn’t spoiled at all.”

Chet looked relieved, as he and the others took their places at the table. Although there was a great deal of bantering during the meal, the conversation in the main revolved around Chet’s missing jalopy and the thief who evidently wore hair disguises to suit his fancy.

Frank and Joe asked Chet if they might take along the gray wig and examine it more thoroughly. There might be some kind of mark on it to indicate either the maker or the owner. Chet readily agreed.

But when supper was over, Callie said to Frank with a teasing gleam in her eyes, “Why don’t you hot-shot sleuths examine that wig now? I’d like to watch your super-duper methods.”

“Just for that, I will,” said Frank.

He went to get the wig from the hall chair, and then laid it on the kitchen table. From his pocket he took a small magnifying glass and carefully examined every inch of the lining of the wig.

“Nothing here,” he said presently.
