With that the woman put her apron over her head and moved away, muttering strange words.

"Ian, what is this mystery?"

It was Ynys who spoke now, for on Alan's face was a shadow, and in his eyes a deep gloom. She, too, was white, and had fear in her eyes.

"How am I for knowing, Ynys-nighean-Lhois? It is all a darkness to me also. But I will find out."

That, however, was easier for Ian to say than to do. Meanwhile, the brown cobble tacked back to Borosay, and the fishermen sailed away to the Barra coasts, and Alan and Ynys were left solitary in their wild and remote home.

But in that very solitude they found healing. From what Giorsal hinted, they came to believe that the fishermen had experienced one of those strange dream-waves which, in remote isles, occur at times, when whole communities will be wrought by the selfsame fantasy. When day by day went past, and no one came nigh them, at first they were puzzled and even resentful, but this passed and soon they were glad to be alone. Only, Ian knew that there was another cause for the inexplicable aversion that had been shown. But he was silent, and he kept a patient watch for the hour that the future held in its dim shroud. As for Giorsal, she was dumb; but no more looked at Alan askance.

And so the weeks went. Occasionally, a fishing smack came with the provisions for the weekly despatch of which Alan had arranged at Loch Boisdale, and sometimes the Barra men put in at the haven, though they would never stay long, and always avoided Alan as much as was possible.

In that time Alan and Ynys came to know and love their strangely beautiful island home. Hours and hours at a time they spent exploring the dim, green winding sea galleries, till at last they knew the main corridors thoroughly. They had even ventured into some of the narrow snake-like passages, but never for long, because of the awe and dread these held, silent estuaries of the grave.

There, too, they forgot all the sorrow that had been theirs, forgot the shadow of death which lay between them. They buried all in the deep sea of love that was about the rock of their passion. For, as of another Alan and another woman, the mirdhei was upon them: the dream-spell of love.
