Toby's Troubles (An Appleton WV Romantic Mystery #4)
Carole Brown

Amy Sanderson who owns the only flower shop in Appleton—Bloomin' Life—is drawn into capturing Toby's “ghost” when her own business is damaged by a destructive intruder. Having loved Toby since a teenager, she's more than willing to join forces with him. But she has no interest in being his best friend or a sister to him. And if she has to resort to schemes of outbidding him at his frequent auction attendences to get his attention, then so be it. She can be just as stubborn as the man who's determined to ignore her love.
In between the break-ins, destruction of property, thefts and personal competitions against each other, Amy and Toby work together to find the thief who seems so determined to find a valuable item, he'll stop at nothing.
