Invitation to a Killer — G.M. Malliet

Crime writer-turned-amateur sleuth, Augusta Hawke finds herself drawn into her second mystery when a celebrity doctor is found dead at a party she is attending!

Callie Morgan is no ordinary aspiring writer. Notorious wife of a Washington lobbyist, Callie believes no publicity is bad publicity and that publishing her scandalous memoirs will help her achieve her heart's desire: a diplomatic posting. She just needs crime novelist Augusta Hawke to be her ghostwriter.

It's hard to say no to Callie, but Augusta does agree to attend her dinner party. The guest list is impressive, and it's Augusta's chance to meet celebrity doctor Doc Burke. But before Augusta really gets a chance to chat with the famous humanitarian, the evening ends in his untimely death.

Signs point to a heart-attack, but Augusta isn't convinced. Especially when his niece tells Augusta about the mystery woman who claimed the doctor's remains.

Augusta decides to host a writer's retreat and invite all the suspects, most of whom are connected in some way with writing. Isn't that what Agatha Christie would do? But the remote lodge soon becomes snowed in and the group starts to crack when it becomes clear the killer may not be finished killing. Can Augusta flush out the culprit before anyone else gets hurt?
