It's a Wonderful Death (Holiday Novella in the Ghosts of Landover Mystery series)

Oh what fun it is to die…

Agnes Dundle died in 1993 after being poisoned at an office Christmas party. All her ghost wants for Christmas today is to know who did it. So she's come to medium detective Carly Taylor for help.

To find the murderer, Carly channels to every 90s moment from the party, but when she visits the aging suspects in the present day, she gets an unexpected surprise. Everyone has used Agnes' death to become a better person, and that makes finding this Christmas spirit's murderer a little hard to do at Christmas.

It’s beginning to look a lot like murder, and you can’t always keep quiet about it, not even when everyone involved would prefer a silent night.
