“Any address on it?” inquired Dorothy.

“Not the slightest bit of writing. If there is any, it’s underneath this outside wrapping.”

Mr. Dixon came out of the house carrying a pail of water, which he brought down to the lawn, where they were waiting.

“Drop that package into the water,” he ordered Bill. “A good soaking will take the sting out of any explosive.”

Dorothy burst out laughing.

“Maybe—but not in this case, Dad. Look, the thing floats!”

She snatched up the package and ripped off the outside paper, disclosing a white cork box, similar to those used for carrying the contraband.

Bill took a knife from his pocket and opened a blade that proved to be a small screwdriver. He took the box from Dorothy and removed the screws from the lid.

“Gee, do you think they’ve sent us a diamond?” she asked jokingly.

“Not a chance. This is a message of some kind, I’ll bet!”
