The Parchment (The Memory of Blood)

Is it possible to cross the
centuries? Documents that certify it appeared in the US. But those who manage to have them
in hand die a violent death.

Ex-police lieutenant Porkelevitch went
on the trail of the killers and transferred the case to the French police for
further investigation on their territory.

The detective agency Mystie Larousse,
whose enrollment has been enriched by a crazy ghost and a pompous vampire,
undertake the investigation. Especially since one of them appeared to star in
the documents.
