He was in a good mood and as soon as he finished breakfast he ran down to the sea, leapt over the breakers and swam out. I suppose he wanted to impress me. I watched as he grew more and more distant, beyond the buoys. He’d left the binoculars on the table and I followed him for a while. His strokes were more energetic than Kloster’s and he was splashing a lot as he kicked his feet, but he didn’t seem to be gliding through the water as smoothly as Kloster had. And he looked as if he was getting tired: he was twisting awkwardly when he lifted his head from the water to take a breath, he was losing his rhythm and his strokes were becoming jerky. He stopped and floated on his back for a while, resting. I thought he seemed agitated…exhausted. I don’t think he was half as far out as Kloster had been the day before. Even without the binoculars I could still make out his head and shoulders in the water. He swam back more slowly and when he was close to the shore, to show off or something, he did the butterfly for the last few yards. I think it was intended for the waitress rather than me. When he got out, breathing hard, I suddenly realised what Kloster’s plan was.”

“Swim out really far and pretend to get cramp, making the lifeguard swim out further than he can manage and become exhausted. Drown the lifeguard.”

“Yes, something like that. I assumed he was waiting for a day when the sea was rough. Then when Ramiro had exhausted himself, swimming out, Kloster would duck him under and drown him. If they were far out enough, at that time of day no one would see.”

“Perhaps only you, with the binoculars.”

“That’s what I found most chilling: he wanted to kill Ramiro in front of me. And afterwards it would be his word against mine. It seemed so incredible, so unreal, I couldn’t tell anyone. At that very moment there were people nearby on sun loungers reading Kloster’s latest novel. And while I was imagining all this Kloster was inside, at the bar, quietly having coffee and reading the paper, apparently not even aware of us. A little later he went for a swim, going out as far as the day before. Then he left, without even glancing in our direction.”
