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."
