“How’s that?” Jeff wanted to know.

“I used to take one little thing for a start, and make up my mind that whoever did it was the one I must suspect,” Sandy explained. “But that’s like trying to prove a man guilty because I think he may be.”

“That’s so,” Dick began to chuckle. “Pinning clues onto folks is like the clothing salesman who tried to sell a white linen suit to a man who wanted a dark grey one. ‘I’ll give you what you want,’ the salesman said—and he went over and pulled down all the shades!”

“And that-there suit looked dark!” chuckled Jeff.

“Now I mean to listen, and watch, and not suspect anybody, as if I had a dark suit and a light one to sell and I’d wait to see who the different suits fitted!”

Breaking into a hearty laugh, Jeff slapped Sandy on the shoulder.

“That-there’s the ticket,” he said.

“By the way,” Captain Parks turned to his employer. “How about that cruise around New York to see the buildings lighted up that you told me to get the yacht ready for?”

“As I live and breathe!” Mr. Everdail slapped his thigh. “I forgot all about our birthday dinner and cruise for Sandy.”

“Well, the dinner was being got ready when you sent for us,” remarked the captain.
