A Lost Letter

Dear Professor Bates,
 
I lent against the door. Three voices – the third wasn't human. One was booming, one smooth and another - screeching. Someone declared, “Ella sal die kaap terug gee aan die Nederlandse!” 
 
 Remember what I taught you, Professor?!
 
 Finally the strange voice spoke. I caught the last word: perfect. How I shivered!
 
I write to you now, John, with every hope that you may receive this. I’m afraid I will not be returning. I trust you know what to do.
 
You have been a better friend to me than I deserved….
 
I love you...
Charlotte
