‘“Poor Amy,” she said. “Poor, poor Amy. She had been looking forward to the bathing here so much. And she was a good swimmer too. I can’t understand it. What do you think it can have been, doctor?”

‘“Possibly cramp. Will you tell me exactly what happened?”

‘“We had both been swimming about for some time—twenty minutes, I should say. Then I thought I would go in, but Amy said she was going to swim out once more. She did so, and suddenly I heard her call and realized she was crying for help. I swam out as fast as I could. She was still afloat when I got to her, but she clutched at me wildly and we both went under. If it hadn’t been for that man coming out with his boat I should have been drowned too.”

‘“That has happened fairly often,” I said. “To save anyone from drowning is not an easy affair.”

‘“It seems so awful,” continued Miss Barton. “We only arrived yesterday, and were so delighting in the sunshine and our little holiday. And now this—this terrible tragedy occurs.”

‘I asked her then for particulars about the dead woman, explaining that I would do everything I could for her, but that the Spanish authorities would require full information. This she gave me readily enough.

‘The dead woman, Miss Amy Durrant, was her companion and had come to her about five months previously. They had got on very well together, but Miss Durrant had spoken very little about her people. She had been left an orphan at an early age and had been brought up by an uncle and had earned her own living since she was twenty-one.

‘And so that was that,’ went on the doctor. He paused and said again, but this time with a certain finality in his voice, ‘And so that was that.’

‘I don’t understand,’ said Jane Helier. ‘Is that all? I mean, it’s very tragic, I suppose, but it isn’t—well, it isn’t what I call creepy.’

‘I think there’s more to follow,’ said Sir Henry.
