I don't remember exactly when my Italian mother-in-law told me that her grandfather was murdered. I've known my husband's mother for almost 30 years, so it must have been during the early part of my romance with her Florentine son that she mentioned that her grandfather had been beaten to death in the family barn. What I do remember however, was how surprised I was by her casual attitude towards the killing. With a shrug and a ‘boh!' (Italian for ‘who knows?'), she told me that the murder had never been reported to the police, had never been investigated and that no one had any idea who would kill her grandfather or why.
