When the body of "how-to" book writer Terry Holiday is found by Aster Paterson in her flower garden, the townspeople of Haven are shocked. But they're even more surprised when the beloved bookshop owner insists that the spirit of her late husband Peter Paterson led her to the grim discovery. Only Aster seems unsurprised--she's been baking his favorite shortbread cookies every day, hoping to lure his ghost back home . . .

Even Maureen is a little skeptical--until Peter's ghost appears in the bookshop window for all to see. Haven's hard-headed realist cop Frank Hubbard is determined to unveil whatever trickery led to the apparition, as he suspects the answer to who killed Terry Holiday may be connected to the illusion.

If Maureen's learned anything since she moved from New England and inherited her haunted inn, it's that 1) ghosts are real (at least some of them), and 2) so are murderers. She doesn't need a how-to manual to solve a murder; she's done it before. But with suspects ranging from a mystery writers group to a ghostwriter who just checked in at the inn, she will need a little help from her spirited sleuths . . .
