French Quarter Clues

Apparently, Marie Laveau can reach beyond the grave...
When Ellen and Sue discover that a demon is attached to Tanya, the three friends fly to New Orleans to enlist the help of a Voodoo high priestess. Soon they learn that Tanya's life depends on them finding and consecrating the remains of a "Devil Child," cared for by Delphine LaLaurie and Marie Laveau.
The key to finding the remains is hidden in a secret diary buried somewhere in a vacant Creole mansion in the French Quarter. It's time for the three friends to renovate and solve another mystery and hopefully live to tell the tale.
