Query: Hidden Riches is a gem

Hidden Riches is one of my favorite books, if I'm in the mood for a saucy romantic mystery this is the one I pull off the shelf.The growing romance between Dora Conrad and her anti-social tenant, former police lieutenant Jed Skimmerhorn is flirty, sexy and sweet.The mystery surrounding a purchase from an estate sale and menacing break ins of Dora's antique shop draw them closer and closer together despite themselves. The resolution of the mystery and romance are both satisfying.Nora Roberts' quirky, eccentric and endearing characters pull me into Dora and Jed's adventure every time. Closing the book is bittersweet.
