Death by chocolate chip cupcake

In the fifth Death by Chocolate Mystery by Sarah Graves, Jacobia “Jake” Tiptree and Ellie White, owners of the Chocolate Moose Bakery, are hired to cater a retired film star’s party in what’s rumored to be Eastport, Maine’s most haunted house…
 

Jake and Ellie are taking a break from perfecting their chocolate pizza recipe to cater a housewarming party hosted by movie icon Ingrid Merryfield. Miss Merryfield is famous for her old-Hollywood glamour. Her new home, Cliff House, has a reputation too—for being haunted. But she isn’t concerned, and some of her guests even try to summon a spirit during the party, using a Ouija board. What arrives instead is a freak autumn storm that downs an ancient tree, trapping everyone on the property and setting the stage for a killer’s planned spree.
 
Though Jake and Ellie don’t intend to get stirred into the mix, there’s no avoiding it—especially when they witness one of the guests being shoved over the very precipice that gave Cliff House its forbidding name.
 
Jake and Ellie begin sifting through suspects and motives, a search that takes them from a long-lost family graveyard to a wise old herbalist’s deceptively-sweet cottage and finally to Cliff House’s overgrown gardens. Is there some ghostly presence involved—or a flesh-and-blood villain? And either way, can they ensure that they avoid meeting their very own, very permanent Hollywood ending?
