At the hospital, a doctor explained that Kevin had advanced kidney disease, and any severe dehydration could be dangerous. The laxative had pushed him into a crisis. He was stable now, but only because Tiffany had called an ambulance the moment he stopped answering. I sat in the corridor, sick with guilt, while she told me everything in a low, unsteady voice.

Tiffany was Kevin’s half sister. Their father had hidden her existence for decades, and a DNA test had revealed her to Kevin last spring. She had taken the secretary job to get close to him, and she was a perfect donor match. The cologne was their late father’s brand, the hotel meetings were her temporary stay and visits with the transplant team, and the pharmacy bag held the medicine he had asked me to pick up under my name. Kevin had kept it all secret because he could not bear for me to see him weak, and because he feared I would blame his family’s lies on him.

When Kevin woke, I told him about the coffee before anyone else could. He cried, and so did I. He admitted his silence had looked exactly like betrayal, and that he should have trusted me with the truth months ago. I did not excuse what I had done, and he did not excuse what he had hidden. We agreed, quietly, that both of us had failed the other.

The transplant happened that winter, and Tiffany recovered beside him in the next room. We went to counseling together, and slowly learned to talk without secrets. Kevin still keeps the “Best Husband” mug, chipped now, on the kitchen shelf. Every morning I make his coffee with my own hands, and I watch him drink it with nothing hidden between us.
