Six levels below the White House lawn, in Annex U36, you lean back in the big red leather chair in the office of J.J. Oscar, director of the Special Intelligence Group. He glares at you through steel-rimmed glasses from behind a massive oak desk.

“Have you ever heard the sounds of the humpback whales?” Oscar asks you. “They’re like organ music – beautiful and eerie.”

“Uh huh,” you reply.

Oscar picks up a letter from his desk. “From Dr. Claude DuMont in Boston to the President of the United States.”

              Dear Mr. President:

While tracking humpback whales near Bermuda last month, we recorded whale songs of a type we have never heard before.

The whales have a secret, and the new whale song is the key. We are analyzing it with our computers. I’ll advise you of our findings as soon as possible.

                                               Respectfully yours,

                                               Claude DuMont
                                               Director, Center for Marine Studies

“If DuMont is correct,” Oscar says, “it's important for us to learn the meaning of the new whale song before anyone else does. For one thing, it will help us find where these whales go when they disappear.”

“What do you mean?” You asked.

Oscar chews on his lip before explaining. “At a time when there should be lots of humpback whales off Greenland, where they migrate to in the summer, they seem to disappear completely. Since they can only stay underwater for 30 minutes, we have a mystery. Where do they go?

“Do you want me to go up to Boston and talk to DuMont?” You ask.

Oscar fastens his eyes upon you as he pauses. “I'm afraid your assignment will be more difficult than that,” he says, “DuMont has been missing for 36 hours. We believe he has been kidnapped by KGB agents led by someone known as “Double-Eye.’”

Oscar pushes a folder across the desk. You pick it up and read a report of how, the day before last, DuMont met with Professor Hans Klein, who agreed to help prepare the computer program that would be used in studying the new whale song. After the meeting, DuMont told Klein he was going straight home. He never made it.

“We've booked you on the next plane to Boston,” Oscar says as you put the report back on the desk. “The helicopter is waiting to take you to the airport. Find DuMont. Find the whale song tape. Your mission is top priority. Your code name is Jonah.”

An hour and 20 minutes later, your 727 Stratojet touches down at Logan International Airport in Boston. You know that Doctor Hans Klein is a key man in the case. Perhaps you should see him first. On the other hand, the scientists at the Center for Marine Studies surely have been following Dumont's work closely. There's a good chance they have important information about the humpback whales.
