I'm currently reading Murder in the Piazza by Jen Collins Moore. This book is the first in the Maggie White Mystery series.
Quickly bored with the leisurely expat lifestyle, Maggie White is excited to have a meaningful job in Rome. Managing a tour company that teaches painting to tourists would be wonderful, if not for her boss, the odious owner. When Maggie finds the man shot dead, she wonders if she'll become a suspect. She's disappointed when the police seem disinterested in investigating. What are the odds it's a robbery gone bad when nothing was taken? Maggie intends to help the police, whether they like it or not, but what happens when she truly becomes a suspect?
