Here's a short story:

CHAPTER XXI 

THE PICTURE IN THE CARDCASE 

"Who is it?" questioned Hans, trying to gain possession of the photograph, but instead of answering Sam started from the cabin. 

"I must show this to Dick and Tom!" he cried. "Come along." 

"Yah, put--" began the German boy, and then stopped, for there was nobody to talk to, Sam being already out of sight. 

"Dick, look what I found," cried the youngest Rover, as he dashed into the pilot house. 

"A fortune?" asked Dick, with a smile. 

"No, a picture. Just look!" 

Dick did as requested and gave a start. 

"You found this on the yacht?" he cried. "Yes. In the pocket of a big coat hanging in one of the lockers. It was in a cardcase." 

"This is certainly queer. It looks exactly like Harold Bird, doesn't it?" 

"It certainly is Harold. I wonder--Oh, look!" 

Sam had turned the picture over. On the back were these words, written in a strong, masculine hand: 

To father, from Harold. Merry Xmas! 

"Why, Harold must have given this to his father," said Dick, thoughtfully.--"And if so--" 

"Do you think the coat belonged to Mr. Bird?" broke in Sam. 

"Perhaps. Did you find anything else?" 

"Ve titn't look," came from Hans, who stood in the doorway. "So dot vos a picture of Harold Pird, alretty! Dot vos kveer!" 

"It is astonishing," said Dick. "Sam, see if you can find anything else." 

Sam went back and Hans with him, and while they were gone Dick, through the speaking tube, acquainted Tom with the discovery made.  (End of story)
