Zara, lawyerly and just a little cynical, teams up with her older—by 11 ½ months—sister Lilly, when a possible Caravaggio sketch and its curator both go missing from a museum. Lilly’s never met a man, or a scam, she didn’t at least wink at, so when the major museum donor who was dating the missing curator turns out to be a handsome, wealthy criminal, Lilly is all in to join the chase. Threaded through this modern-day mystery are flashbacks to a journal kept during World War II by the father of (one of) Lilly’s boyfriends. As the search moves from San Francisco to New York City to Alsace, France, the stories come alive in the old barn where the curator and the Caravaggio may, or may not, be hiding. This book is part of the Zara and Lilly mystery series featuring Zara and Lilly, two mature sleuths whose humor, failings, and wisdom prove endearing and entertaining.
