Italy to Die For by Loretta Giacoletto
From The Savino Sisters Mystery Series. Too much togetherness spells disaster for these thirty-something sisters vacationing in Italy.
When glamorous Margo opts for a steamy romance in Florence, plain-Jane Ellen travels alone to their next destination, a charming hillside villa at La Spezia. The owner Lorenzo, a mysterious widower, insists on showing Ellen around Cinque Terre, five picturesque villages overlooking the Ligurian Sea. Ellen is determined to experience the local culture but instead encounters intrigue in Monterosso el Mare where gypsies are turning up dead faster than Lorenzo can show her the sights. Then Margo arrives, and soon discovers her own life is in danger.
