"I can go you one better!" asserted Green, positively. "Remember, Mr. Forrester, the man's silhouette I saw on the Prentices' lawn that night—the man who—"
"Yes—yes," interrupted Forrester, quickly, fearing that Green was about to mention the girl before Humphrey.
"That looks like the same silhouette!"
"And now," cried Humphrey, "I want to show you something that is even more puzzling. Do you happen to have a magnifying glass, Mr. Forrester?"
"Yes," said Forrester, opening the drawer in the table and taking out a large reading glass.
"Hold the glass over the opening in the tree," instructed Humphrey. "Do you see anything?"
Forrester adjusted the glass to different distances, while he examined this part of the photograph.
"Yes," he agreed, after a time, "there seems to be a thin black object inside the opening. It may be my package."
"No," protested Humphrey. "This looks like a black rod with a bright or white spot near the end. Can you make it out, now that I have explained it?"
"Yes," acknowledged Forrester, "but I cannot even make a guess at what it can be."
