Steve Ames walked around the objects on the laboratory table. "Nothing deadly looking about these gadgets," he said. "Which goes to show how misleading appearances can be."

The objects included the barber's massage machine, an ancient composition-board suitcase, the gadget from the houseboat, and a TV set with an indoor antenna of the kind known as "rabbit ears."

Parnell Winston admitted, "There is plenty we don't know about them, especially the inside of that TV set. But we'll learn."

Steve smiled at the assembly of faces. In addition to the project team and the boys, Mrs. Brant, Mrs. Morrison, and the two girls were in the group. So was Joe Blake.

Rick regretted that Jerry, Duke, and Cap'n Mike could not be invited. But the matter was still not for discussion with people on the outside. If a story ever could be made public, the Morning Record would be the first to have it, but in all probability the facts would remain buried for some time.

In a large room in the lab basement the four houseboaters and the barber waited under heavy guard for the arrival of a Coast Guard cutter. The barber was there courtesy of Captain Douglas, who had picked him up and delivered him to Spindrift after a call from Joe Blake.

Steve rapped for attention. "We're about to tie up some loose ends, everyone. Let's get seated, because the cutter will be here any moment."

The room was sometimes used for lectures when Hartson Brant got his entire staff together, and there were plenty of chairs. In a moment the audience was seated comfortably and listening to Steve.

"You were all involved," the agent began, "so I want you all to know what has been going on. Some details are not known to us, yet. But we're continuing the investigation. However, the part that involves you is finished, and you'll probably never hear about the rest of it."

Rick knew that was true. Who the houseboaters and the barber really were, who paid them, how they had been tipped off to the project in the first place, and similar details would remain locked in top-secret files somewhere in Washington.
