The aroma of stale coffee hung heavy in the air. John stifled a groan, rubbing the back of his neck. This was a soul-crushing job, sorting through his grandfather's belongings. His head was pounding.

He pulled a file from a battered briefcase. Inside, nestled amongst yellowed memos and faded photographs, was a draft of a letter. The formal language and precise formatting of the letter stood out. It was a resignation letter, his grandfather's decision to leave a company he had dedicated his life to.

John sank into a nearby chair, his muscles aching. He blinked repeatedly, the words on the page blurring. The room began to spin slightly. He wasn't sure how much longer he could continue.
