"It's from Selena Davis." She blurted out loud, then proceeded reading aloud what the note contained. "One of these days, a jealous wife would be tired of your bullshit and pull a trigger to your head. I have prepared your coffin in advance. Thank me later when we see each other again."

Reeling with shock, the nurse collapsed on the nearby chair while still clutching the note in her trembling fingers.

"World war three has just begun." She said rather dramatically. If it weren't for the graveness of the situation, I would have laughed at her over the top reaction. 

"Selena Lewis?" I repeated the name she mentioned, trying to remember if we're acquainted. But with my condition, nothing came to my mind. I certainly don't know her. If I do, I still won't remember. Amnesia erased my memories.

"It's not Lewis but Selena Davis." The nurse rectified. Her smooth tone remained polite.

"Who is she?" I blurted out aloud.
