Counterspy - The Case of the Insidious Impersonation

Counterspy Agent David Harding is receiving a message from Agent Ferguson in Washington. Ferguson says "Urgent, reference Confidential File R33X". Harding says "Go ahead, Ferguson". Ferguson says "The State Department requests that you personally meet the ocean liner S.S. Tregania, which is scheduled to arrive at 10:00 A.M. in New York, Pier 33". Harding says "All right Ferguson, notify the party's concerned that I'll board the Tregania at the Ambrose lighthouse". Ferguson says "Yes sir, will do". Harding then makes another call to Agent Peters. He says "Peters, notify Spalding that I'm putting him in charge of our present operation here on the west coast until you and I get back. Now, after you talk to Spaulding, call the airport and order the jet to be ready for a take-off within an hour. We're making an emergency flight to New York, Peters. I'll give you the details on the way". Later, while on the flight, Peters asks "Well, Mr. Harding, how about those details?" Harding says "Peters, we are flying to New York in regards to Confidential File R33X. That's the code number for a special mission to Washington by Mr. Ramon Sierra". Peters asks "The Philippine Statesman?". Harding says "Yes, Mr. Sierra and his aide, Colonel Manuel Quinto are scheduled to arrive in New York tomorrow morning". Peters says "I don't get it, David, why New York?" Harding says "Well, Mr. Sierra is ostensibly taking a long ocean voyage for his health". Peter asks "Is this a cover-up for his business here?" Harding says "Exactly, very careful plans were made not to arouse the suspicions of espionage agents in the Philippines. The secret conference in Washington will deal with a defense plan for the islands in case of a surprise attack, like what happened in Korea".
