A guest list fit for Agatha Christie is invited to the grand seaside hotel as All Hallows' Eve ushers in the most surprising of birthday events....

It looks like a perfect Cornish autumn, with Maisie Clark still finding creative inspiration for her writing while working as a maid at the historic Penmarrow Hotel. Between the staff of quirky co-workers, glamorous and unusual guests — and her growing friendship with the charming but mysterious Sidney Daniels – Maisie is living out adventures instead of just penning them in the pages of her would-be Gothic novel's growing number of chapters.

But even Maisie's imagination can't conjure the unusual event this Halloween brings to the Penmarrow: an eccentric earl's lavish birthday celebration that includes a pretty (and perceptive) young psychic whose predictions seem to have everyone on edge — and, to Maisie's delight, the elusive novelist Alistair Davies is rumored to be part of the guest list! But with the earl's bickering relatives and illustrious friends on hand— and more than one ghost of the past waiting to be revealed — it's anyone's guess what the festivities will bring before the party is over.

Will the psychic foretell doom for the earl's gathering—and is her 'gift' as genuine as it seems? Will Maisie finally meet her favorite author face to face? And, more importantly, what about the romantic sparks that fly between Maisie and Sidney as he introduces her to the village's version of a Cornish Halloween?
