Olive You to Death by Lynn Cahoon

In the coastal town of South Cove, June is tourist season—and wedding season. Unfortunately, Jill Gardner’s own wedding has been delayed. But that just gives her more time to search for a missing bride—and a killer . . .
Things are looking up for the owner of Coffee, Books, and More—Jill’s finally getting her MBA, and though her wedding to police detective Greg is postponed a few months, she still has plenty to celebrate. A girls’ weekend in Santa Barbara is just the ticket. But back in South Cove, someone else’s big day has become a big problem. Antiques dealer Josh Thomas and Mandy Jensen were planning a small private ceremony under an olive tree on the historic Jensen farm—until Mandy went missing . . .

Is this a case of a runaway bride—or a guilty groom? Greg zeroes in on Josh but finds him so annoying that he quietly asks Jill’s help in keeping his number-one suspect distracted. She knows that Josh is searching for something else besides his fiancée—a bank robber’s buried gold bullion. And when the professor he’d been discussing it with turns up dead, she can’t help wondering if what looked like cold feet was actually cold-blooded murder . . .
