St. Grimald priory is now free of invasive ghosts, and everyone's attention turns to entertaining Felicity Smedley, Prudence Honeysett's "witch-like" best friend. Under her gentle guidance, Freddy grows even more as a gifted medium and takes it upon himself to work on things outside priory walls. But while practice makes perfect, it also leads Freddy down an unexpected road involving a ghostly mother's plea. The encounter reopens wounds from the recent past and darkens his idyllic life under his aunt's ever-watchful and protective eye.

Meanwhile, Jonathan Beverly's efforts at clearing out his late uncle's hoard unearths an old inkwell, one that comes with its own genie-like ghost. And not just any ghost at that—Mr. Murgatroyd is an obnoxious busybody, a terrible gossip and family chronicler who's determined to annoy the staid Mr. Beverly to distraction with endless accounts of the family's history of wild living.

And all that in addition to escalating family drama in the Bisset household, forcing Antigonous to reach out for help from Prudence, Felicity, and the ever-despairing Linford, his unfortunate firstborn.

The dust hasn't quite settled yet as more madcap adventures are recounted in letters and journal entries in this installment of Ghosts and Tea.
