"I tell you what we'll do," said Walter, with sudden inspiration. "We'll take some fishing tackle--Grace and I have enough to go round--and go out in the little old _Bargain Rush_ to a place I know of where the fish just come trotting up begging to be caught. How about it, girls? Are you on?"

It seemed that they were, enthusiastically so, and half an hour later Grace was declaring that she was sorry about poor Nan's wrist, of course, but if this wasn't better than playing a hot game of tennis and probably getting beaten, her name wasn't Grace Mason, that's all.

Walter was right about the fish--they seemed to enjoy being caught, and when, almost at noon time, they came back to the hotel with Walter bringing up the rear with the result of the morning's sport proudly displayed, strangers followed them with envious eyes and people they knew stopped them to ask where they had found the fish.

As for Nan, she tried hard to enter into the old round of gaieties with her usual enthusiasm, for she knew that to show how worried she was would only spoil the fun of her friends. But to herself she acknowledged that she would not really be able to enjoy anything again until the mystery of those dangerous papers in her bag was finally cleared up and she was free from espionage once more.

Walter seemed to be the only one who really understood her state of mind and when she pleaded a headache that afternoon and broke an engagement with the girls to go to the cocoanut grove for tea, it was Walter who silenced their protests and took her himself up to her room.

"I'm awfully sorry about this," he said, taking the wrist, which had been rubbed with liniment and neatly bandaged by Mrs. Mason, in one of his sunburned hands and patting it awkwardly. "Does it ache very much now?"

"N-no. It doesn't ache at all," said Nan, adding quickly to cover her confusion as she drew her hand away, "I think you had better go down to the girls now, Walter. They will think you've deserted them."

"Oh, all right," said Walter, and perhaps it was only Nan's imagination that made her think he looked hurt. "Be sure and save the first two dances for me to-night."

He went out quietly, and for a long time after he had gone Nan stood looking at the closed door. Then her glance dropped to her bandaged wrist and she smiled a little.

"Boys are so funny," she murmured--to no one in particular.

There was a big dance that night, and when the time came to dress Nan still further incensed the girls by refusing to dress.

"How would I look in an evening dress and--this thing?" she asked, holding up her bandaged wrist.

"No one ever would look at your wrist when your face is along, Nan Sherwood," said Rhoda, at which Nan laughed but still remained firm.

"Oh, well," said Bess, flouncing over to her closet and taking out a pretty white net and blue satin dress, "I suppose you will have your own way, Nan. But one way or another, that old Mrs. Bragley and her miserable papers have just spoiled our trip. I wish she was in Jericho!"

"It was Guinea last time," Nan laughed at her.

Since Nan refused to dance that night, Walter also refused. Try as she might, Nan could not get him to alter his decision, and finally gave up the attempt in despair.

"Grace and Bess will be furious," she said.

"Let them," he answered recklessly. "There are plenty of other fellows around. See that moon over there? Say, Nan, I have a bully idea."

They were standing in one corner of the veranda of the Royal Poinciana.

The veranda looked strangely deserted that night, the dance being at its height in the ballroom within, and it being still a little early for the inevitable drifting of couples from the heat of the ballroom to the cool breezes of the porch.

"An idea?" asked Nan, feeling adventurous herself. "Tell me."

"Back there somewhere the _Bargain Rush_ is waiting," said Walter, his voice boyishly eager. "Since we can't dance, we might as well 'putt.'

And--it seems too bad to waste that moon."

Nan thought so, too, and a moment later they were running hand in hand through the garden to the spot where the _Bargain Rush_ waited. They scrambled on board, Walter started the engine, and they drifted out into the magic stillness of the night.

"Now tell me," said Walter after a while, his eyes shifting from the moonlit waters of the lake to Nan where she sat curled up in one of the chairs, gazing dreamily out over the shadowy water, "isn't this better than dancing?"

"It's awfully nice," admitted Nan.

"I get so tired of the hot ballroom, and the bright lights," went on the boy, as he bent over the engine, to see that it was running properly.

"Well, I get tired of the lights myself, Walter."

"And those flashing jewels! Why will some of the women load themselves with so much jewelry?"

"I'm sure I don't know. I think too much jewelry is horrid."

"I suppose some folks think that is the one way to let others know that they have money."

Nan drew a deep breath. "Look at the moon, Walter, isn't it simply wonderful?"

"Sure is. And I think----"

Walter came to a sudden stop. Another motor boat had loomed up, running dangerously close to the _Bargain Rush_.

"Hi, keep away from there!" called out the boy.

"They'll run into us!" exclaimed Nan, in sudden alarm.

"Don't get scared, sonny!" sang out a man in the other motor boat and then he suddenly veered out of the way, but with only an inch or two to spare.

"The great big clown!" burst out Walter, in just anger. "He did that just to give us a scare."

"It was no way to do," said Nan. She was not a little shaken by the unexpected happening.

"I hope he runs into a tree, or a rock, or something."

"There he goes, along the other sh.o.r.e of the lake," said Nan, a few seconds later. "See, I think he is trying to scare the folks in that other motor boat."

"He's either crazy or a fool," murmured Walter.

The unknown motorist was evidently amusing himself at the expense of those less daring than himself, and he raced up and down the lake several times. But soon a larger motor boat put out and bore down upon him.

"We've been laying for you," said a man who was evidently an official.

"You'll not try any more of those tricks."

"That's right--place him under arrest," said another man, one who had come close to suffering a collision. "I'll make a charge against him."

"I was only having a little fun," whined the man who had been racing around.

"You can tell your story at the police station," was the answer. And then the fellow was placed under arrest.

Nan and Walter continued their ride in the moonlight, and soon the unpleasant incident was forgotten. They talked of their good times at Palm Beach, and then the youth referred to what Nan proposed to do for Mrs. Bragley.

"Nan, I'm awfully sorry you are so worried about those old property papers," remarked Walter presently. "Why don't you turn them over to my dad?"

"I thought you'd say that, Walter," she returned. "I've been expecting it. Why don't I? Well, to tell the truth, I don't know. I--I guess I am a little headstrong about it."
