Not Worth Dying For — Loretta Giacoletto

What would it take for thirty-something sisters Ellen and Margo Savino to cut short their Italian holiday and return St. Louis? Their mother Toni's connection to the murder of Val Corrigan, that's what. It seems the widow Toni shared Val's affections with her clueless best friend among other women, one who later winds up dead. While attempting to prove their mother's innocence, the sisters' amateur sleuthing leads them to the decade-old renovation of a building located in the former St. Louis Garment District. El and Margo soon discover that greed and corruption within the construction industry resulted in deadly consequences for more than one victim. It's up to the sisters to convince hard-nosed Major Case Squad Detectives Sam Reardan and Guy Winchester who resent the outside interference. If that's not enough, the sister's Nonnie Clarita's long ago WWII teenage lover has traveled from Italy, determined to renew their romance and establish a relationship with Toni, his unacknowledged daughter.
