Buckingham Pet Palace may provide services fit for a four-legged king, but there's no use crying over spilled kibble--not unless it leads to murder!   When a break-in at the Pet Palace robs Sue Patrick of more than her beauty sleep, she intends to tidy her ransacked doggy daycare and spa before making any rash decisions. But after Sue abandons her better instincts to rescue a petrified pug stranded at a lighthouse in the Delaware Bay later that morning, she's lured off mainland Lewes long enough for a freshly murdered body to get dumped in her driveway . . .     Aided by Lady Anthea Fitzwalter, her practically royal business partner from across the pond, Sue sniffs out clues about the yappy pug with a complicated history and the old car spotted at both crime scenes in hopes of IDing the culprit. As the investigation leads them back to the bay, the ladies soon find themselves immersed in a case trickier than a canine agility course--and chasing after a well-groomed killer who will do anything to maintain a perfect reputation . . .
