The Rialto Fish Market in Venice and the adjacent vegetable market was the scene this morning of a disturbing, hackle-raising crime. A large cernia or Dusky Grouper, was caught red-handed, er, red-lipped with the goods, a string of pre-season pomodorini clearly in the process of being consumed. He is being held on boxes in the market and ordered to pose for tourist pictures. His attorney is appealing the sentence as being too harsh. He’d rather be sauteed, according to a close source.
