The first chapter calls to mind the opening scene of an operetta in which the entire chorus rushes onstage brandishing wine jugs. To be fair, Ms. Trinchieri’s characters content themselves with talking rather than singing, but the effect is still a little dizzying ... Ms. Trinchieri plants clues that variously point to the widow, the son and the mistress ... Nico’s own history emerges only in brief references to his deceased wife and his past career. If there is little depth to his character, however, there is charm in his easygoing manner ... The novel’s final revelation is relatively subdued, its force blunted by diversions into details of love affairs, petty feuds and, of course, food. A telltale 'bloodied brooch' adds the requisite touch of melodrama.
