Picture a man named John on vacation with his family along the coast of the Mediterranean. They’ve just finished dinner and are enjoying a casual stroll to their hotel. The air is warm, the breeze is cool, and ocean waves are crashing into the shore. It’s like something from a postcard.
It’s at about that time John notices someone following them. A few steps later, another man appears from a side street up ahead. Now the man in front and the man behind start closing in.
