‘Just for curiosity, as I went out that evening I glanced at the hotel register. I found the names easily enough. Miss Mary Barton and Miss Amy Durrant of Little Paddocks, Caughton Weir, Bucks. I little thought then how soon I was to encounter the owners of those names again—and under what tragic circumstances.

‘The following day I had arranged to go for a picnic with some friends. We were to motor across the island, taking our lunch, to a place called (as far as I remember—it is so long ago) Las Nieves, a well-sheltered bay where we could bathe if we felt inclined. This programme we duly carried out, except that we were somewhat late in starting, so that we stopped on the way and picnicked, going on to Las Nieves afterwards for a bathe before tea.

‘As we approached the beach, we were at once aware of a tremendous commotion. The whole population of the small village seemed to be gathered on the shore. As soon as they saw us they rushed towards the car and began explaining excitedly. Our Spanish not being very good, it took me a few minutes to understand, but at last I got it.

‘Two of the mad English ladies had gone in to bathe, and one had swum out too far and got into difficulties. The other had gone after her and had tried to bring her in, but her strength in turn had failed and she too would have drowned had not a man rowed out in a boat and brought in rescuer and rescued—the latter beyond help.

‘As soon as I got the hang of things I pushed the crowd aside and hurried down the beach. I did not at first recognize the two women. The plump figure in the black stockinet costume and the tight green rubber bathing cap awoke no chord of recognition as she looked up anxiously. She was kneeling beside the body of her friend, making somewhat amateurish attempts at artificial respiration. When I told her that I was a doctor she gave a sigh of relief, and I ordered her off at once to one of the cottages for a rub down and dry clothing. One of the ladies in my party went with her. I myself worked unavailingly on the body of the drowned woman in vain. Life was only too clearly extinct, and in the end I had reluctantly to give in.

‘I rejoined the others in the small fisherman’s cottage and there I had to break the sad news. The survivor was attired now in her own clothes, and I immediately recognized her as one of the two arrivals of the night before. She received the sad news fairly calmly, and it was evidently the horror of the whole thing that struck her more than any great personal feeling.
