One benefit of being part of the President's staff was that he had excellent personal security when he wanted it, and the best technical security services as a matter of course.  The Secret Service and other government agencies worked very hard and very regularly to make sure that his phone lines were secure.  The FBI would have to clear any tap with them, and would also have to get a court order first, neither of which had been done.  Cutter called a WATS line number-with a toll-free 800 prefix - and spoke a few words.  Had anyone recorded the conversation he would have had a problem explaining it, but then so would the listener.  Each word he spoke was the first word on a dictionary page, and the number of each page had three digits.  The old paperback dictionary had been given him before he left the house in Panama, and he would soon discard it.  The code was as simple and easy to use as it was effective, and the few words he spoke indicated pages whose numbers combined to indicate map coordinates for a few locations in Colombia.  The man on the other end of the line repeated them back and hung up.  The WATS-line call would not show up on Cutter's phone bill as a longdistance call.  The WATS account would be terminated the next day.  His final move was to take the small computer disk from his pocket.  Like many people he had magnets holding messages to his refrigerator door.  Now he waved one of them over the disk a few times to destroy the data on it.  The disk itself was the last existing record of the soldiers of Operation SHOWBOAT.  It was also the last means of reopening the satellite radio link to them.  It went into the trash.  SHOWBOAT had never happened.
