Edward St Aubyn’s ‘Patrick Melrose’ novels were loosely autobiographical renderings of the author’s harrowing, rarefied, drug-sozzled existence. Despite their subject matter, they managed to be uplifting through the beauty in which they expressed their melancholy sentiments. After At Last, the final novel of the pentalogy, St Aubyn published Lost for Words, a prickly satire on the literary prize culture that seemed narrowly parochial for such a classy novelist.
