Las interioridades would roughly translate to Interiors, and it is the title of the first of six short stories or tales which incorporate fantastic elements in otherwise common lives. Palma's style is a little bit flowery, but I think his word choices are key to making this collection stand out. He often comes up with very unusual images and metaphors. I'm very picky about metaphors and similes since they are so often misused and make no sense, but these are perfect.
The stories are not only well-written, but also intriguing and entertaining. I was glued to the book. As in every collection, some stories are better than others, but the good ones are so good they compensate the others. In short, I'm not disappointed by this early volume, but I expect a more depurated style in his later work, more similar to the Victorian Trilogy.
Because it is such a short collection, I'm going to go a little bit more in-depth with each story and there will be spoilers. I have tried to translate the titles, so bear with me.
