So, after Dipper's "Fruitful Recipe", we have Hypnos's "Fruitless Effort". Can we now expect puzzles with titles such as "Fruit Cocktail", "Fruit Machine", "Fruit Salad", and "Fruitcakes"? If not,there are some challenges for setters.
I was a bit of a caterpiller (in the BRB's archaic definition) when it came to completing this one, but the solution emerged when I finally "spotted" the beautiful Nabokovian finish. Although, like Dead-eye, I was expecting another [perhaps less totally thematic] form.
I disagree with those who think that the inclusion of proper names is [bordering on] unfair. In a good Listener puzzle one can expect about half of the lights to be rare or uncommon words, of which a regular solver may not have heard of about a half until looking them up in the BRB. [D S MacNutt, in "Ximenes on the Art of the Crossword" recommended that there should be equal numbers of common and rare words in a barred puzzle.] Some will also have to look up unfamiliar quotations in the ODQ or elsewhere. There is therefore no reason why one shouldn't have to use other reference books to find proper names that are equally unfamiliar.
