The aroma of freshly brewed coffee, the morning newspaper spread out before him – it was the perfect start to David's Saturday. He was looking forward to a relaxing day with Susan. He was buoyant and his chest felt light.

A small, inconspicuous envelope sat on the kitchen counter. It had Susan’s name on it. He almost ignored it, but something made him pick it up. He was now feeling curious.

As he scanned the numbers, a wide smile spread across his face. He began to laugh. This was a triumph, a complete game-changer. He was going to have a fantastic day!
