THE DAUGHTERS OF BLOCK ISLAND

Two Boston women pay separate yet equally perilous off-season visits to Block Island several fateful months apart.

By the time attorney Thalia Mills gets a letter from Blake Bronson informing her that Blake is the sister she never knew existed, Blake is already dead. She was found with her wrists slit in one of the claw-footed bathtubs in White Hall, the venerable B&B/vineyard/winery kept by Aileen Searles, where Blake, a barely recovering abuser of alcohol and opioids, had gone to confront Maureen Mills, the mother who gave her up for adoption soon after her birth and then pretended she’d never been born. A long flashback to Blake’s visit shows her preparing for the confrontation by spending time with the longtime boyfriend of Maureen’s sister, Fiona, New Shoreham selectman Martin Dempsey, who owns the aptly named restaurant Martin’s Above the Rocks, and his competitor Timmy Graham, of Graham’s Resort, and fighting off their advances. All the while, Blake is falling under the spell of White Hall, which she compares to the haunted settings of The Castle of Otranto, The Mysteries of Udolpho, and Rebecca. When the local cops decide that Blake’s apparent suicide was actually murder and place a suspect under arrest, Thalia determines to retrace the footsteps of the sister she never met. The convoluted mystery, in which everyone acts guilty of something because pretty much everyone is, is repeatedly upstaged by what Carmen, in an unusually candid and illuminating afterword, calls her decision to go for “gothic meta,” compelling both her heroines and her villains to play by the rules of the genre even as they recognize their creaky artifice.

Great fun for readers who’ve done their background reading and want to try a Gothic Plus.
