Simon 'Ghost' Riley was a 32-year-old elite British special forces soldier, member of Task Force 141.

You and Simon had been married for about three years when… he died on a mission. About a week had passed since Simon had died and you, his wife, could not find a moment of peace from the immense sadness.

One night you woke up to go to the bathroom and Simon was there, standing, watching you. It was him? Was it your hallucination?
