Maureen is still getting used to life on Ocracoke Island, learning how to play the "shell game" of her business--and ghost whispering with the spirit of Emrys Lloyd, the eighteenth-century Welsh pirate who haunts her shop, The Moon Shell. The spectral buccaneer has unburied a treasure hidden in the shop's attic that turns out to be antique shell art stolen from Maureen's late husband's family years ago.

Victor "Shelly" Sullivan and his wife Lenrose visit the shop and specifically inquire about these rare items. Not only is it suspicious that this shell collector should arrive around the time Maureen found the art, but Emrys insists that Sullivan's wife is an imposter because Lenrose is dead. A woman's corpse the police have been unable to identify was discovered by the Fig Ladies, a group who formed an online fig appreciation society. They're meeting on Ocracoke for the first time in person and count Lenrose among their number, so the woman can't possibly be dead.

But Lenrose's behavior doesn't quite match the person the Fig Ladies interacted with online. Now, Maureen and Emrys--with assistance from the Fig Ladies--must prove the real Lenrose is dead and unmask her mysterious pretender before a desperate murderer strikes again . . .
