“One of you boys thinks that perhaps it isn’t?” Sam looked puzzled.

“No.” Ken smiled at him. “But we have reason to believe the box is lighter now than it was when my father brought it here. And we didn’t see how the repair job could have changed the weight.”

“It didn’t. I just straightened the lever. Do you think I exchanged your box for another one?”

“Of course not,” Ken assured him.

“But you think maybe someone did, eh?” Sam fitted his jeweler’s glass into his eye. “It sounds like nonsense, but let’s have a look.”

After several minutes he removed the glass and shook his head. “I can only say that I think this is the same box I worked on. The lock mechanism is the same. But I was in too much of a hurry to inspect the box carefully. Still, I couldn’t testify under oath that this is it.”

The phone rang and Sam excused himself to answer it.

“Satisfied now?” Sandy asked Ken.

Before Ken could answer, Sam was calling him.

“This is for you, Ken,” he said.
