Selkies are one of my favorite mythical/supernatural creatures, no doubt related to the melancholy nature of the legends told about them. Look, if it’s not absurdly bloody, heart-crushingly sad, or at least suitably bittersweet, it’s no good. And the various selkie legends have got those criteria covered.
If we learn anything from tales like “Bluebeard” and “How the Devil Married Three Sisters,” it’s that the real crime is not disobedience or even murder–it’s lack of caution. After all, the only reason anyone in those stories got caught–both the women and their homicidal husbands–wasn’t stellar detective work, but their own carelessness in tracking blood around or giving people access to their murder-room.
What I like best about this tale–besides, you know, all the killing and trickery it involves–is that there are so many tales featuring murderous suitors brought to justice.
