Well, actually it's five stars for the beautiful and long (65 pages!) introduction wrote by the same author 20 years later.
Those pages are an ode to creativity, irony, wit, romanticism, all.
In comparison the short stories are not that good. Not that original, I have to say, similar to some things written by Giorgio Bassani.
Delfini chose Modena (M*** for him), while Bassani chose Ferrara.
Anyway, this writer has to be re-discovered as his books are kind of impossible to find and not printed anymore. Yet I have the impression he could have written better things and maybe he did and I don't know about their existence. Will check it better.
