The Busy Woman's Guide to Murder — Mary Jane Maffini

When murder gets messy and the clues get cluttered, professional organizer and amateur sleuth Charlotte Adams steps in to restore order. In Mary lane Maffini's latest, Charlotte suspects her 911 operator is the one who's been busy...settling some old scores.

Mona Pringle, the local 911 operator, is calling Charlotte Adams for a change. She's having her own emergency: Serena Redding, one of the "mean girls" in high school who used to torment Mona, is coming back for a reunion. When Mona talks about how good it would feel to kill Serena, Charlotte doesn't believe she means it. But then a woman who looks like Serena is killed in a hit-and-run -- and no one knows where Mona is. After another former mean girl is also run down, Charlotte realizes she needs to look both ways for the missing Mona -- before a murderer strikes again.
