I have suddenly remembered with a painstaking level of detail a supernatural short story I have read in the late '90s or early '00s, most likely in Italian or - less likely - in English in a school anthology book, but my search engine skills have failed me badly and I can't identify it.
The protagonist is an artist that, after being struck by inspiration, draws a corpulent man under trial, in the defendant seat, nervously crumpling his hat among his hands and looking very disconcerted. Content with his drawing, the protagonist then goes to the city for a walk and sees a gravestone with his own name and the current date in front of a shop.
The owner of the shop - the sculptor - turns out to be the man he drew in his cartoon. Finding out about this incredible coincidence, they decide to have dinner together, after which the protagonist starts writing something in his diary about hearing the sculptor preparing his tools for something.
The story ended there, but the implication (never stated explicitly) was that the sculptor murdered him - effectively making the gravestone predicting his death and the cartoon predicting the trial that would have ensued.
I have tried several combinations of "suspense short story drawing trial sculptor gravestone" and other combinations of related words, but nothing turned out.
Any ideas on what that might be?
