“I’ve never seen such an elegant display,” Penny whispered in awe. “Do you suppose that picture is one of the gifts?”

She indicated an oil painting which stood on an easel not far from the table. So many guests had gathered about the picture that she could not see it distinctly. But at her elbow, a woman in rustling silk, said to a companion:

“My dear, a genuine Van Gogh! It must have cost a small fortune!”

When the couple had moved aside, Penny and Salt drew closer to the easel. One glance assured them that the painting had been executed by a master. However, it was the subject of the picture which gave Penny a distinct start.

“Will you look at that!” she whispered to Salt.

“What about it?” he asked carelessly.

“Don’t you notice anything significant?”

“Can’t say I do. It’s just a nice picture of a drawbridge.”

“That’s just the point, Salt!” Penny’s eyes danced with excitement. “A drawbridge!”

The photographer glanced again at the painting, this time with deeper interest.
