Dr. Fletcher took a deep breath before she opened the
envelope. The letter was from Enrique, whom she had not
heard from in two years. "My dearest doctor," the letter
began. "Where do I begin? As you know, we met under the
palms of the Nile on a steamboat called the Emerald
Messenger, at a card table to be exact. I believe the game
was bridge. Do you remember? That night, I gave you a
package, which I hope you haven't opened. You kept asking
me what was in the package, and I kept avoiding the
question. Well, it is time you knew."
