“Just the letters, you say—JW for CS?” Mr. Brewster exclaimed. “Let’s go back to my room. I want to see them for myself.”

The Brewsters and the Mahenilis went up the stairs. As they neared Mr. Brewster’s room, they noticed its door was open.

“Now what can that mean? More trouble? That door was closed.” The question flashed through Biff’s mind, but he did not speak.

The door, it developed, had been left ajar by the maid, but it was what she was doing that upset Thomas Brewster.

They entered the room just in time to see the maid wipe the soap message off the mirror.

Thomas Brewster started to speak, but he realized that she was only doing her job. When the maid left the room, Mr. Brewster questioned his son closely.

“Now this is important, Biff,” he said. “Can you remember exactly how those letters were written? I mean, were they all capitals? Or was one or more of them in lower case?”

“Lower case?” Li looked puzzled.

“He means small letters, Li. Now let’s see, Dad. I’m almost positive that the J and the W were capitals. How about you, Li? Is that how you remember it?”

The Hawaiian lad nodded his head.
