Battle between assassins

The moment Fade stepped foot on the best position he found to use his rifle he heard a very faint sound of something similar to an alarm. 

'Oh, a trap,' Fade smiled under his mask as he changed his position. 

...

Catherine Walker was on the top floor of her recently acquired high-rise building when she suddenly received a message from the assassin that she and the others hired. 

"Hide in your panic room, Fade's target is you." 

The moment she saw this message she quickly called her guards to escort her to the panic room. 

...

After he was done sending his message John got into position as he held his beloved rifle the Scorpion and looked through the scope of his rifle. The area where the alarm rang was now empty but John knew that even if Fade was a martial artist he shouldn't have gone too far. It was also hard to find any other area to kill Catherine Walker.
