On North Carolina’s Okracoke Island, Maureen Nash sells exquisite seashells to locals and tourists—with Bonny the shop cat and the ghost of a Welsh pirate for company. And when needed, she steps in to help the police solve a murder…

Dr. Irving Allred is boasting around town that he’s about to get his hands on an authentic haunted sword. But minutes after Maureen hears the story, a woman walks into the Moon Shell, sword in hand. She found it while walking her bulldog on the beach—and its blade is stained with what looks like blood. Looks like it’s time to call the sheriff’s department.

Allred is furious that his prize is now in police custody—and even more agitated that an unknown buyer was trying to outbid him. He’s convinced that the sword will lead him straight to the ghost he’s hunting. He’s not the only one on the Outer Banks who’s been searching for spirits, though. An odd visitor also showed up at Maureen’s shop claiming the ability sense them . . . though somehow she didn’t seem to notice Maureen’s spectral friend hanging about.

When a man who’d been camping nearby is found cut down along the shore, Maureen starts providing some unofficial assistance to Captain Rob Tate by digging into the island’s maritime history. But it’s not the only mystery she’s facing—because the shop’s resident ghost is seeing ghosts himself . . .
