They closed the door on the cabin. There wasn’t room enough for them to stand, so they fell into each other’s arms on the bunk.Sam kissed her and tried not to think that it was for the last time.He was happy. That was the hell of it. He was finally happy. Right here, right now, in this place, with this girl in his arms, he was happy. Was that why he felt the hammer about to fall on him? No, that was crazy. He was happy. Happiness didn’t mean that tragedy was coming around the corner. Did it?
