Inspector Delmar Hubert of Brussels Homicide is well accustomed to unusual cases. In fact his speciality is delving into the dark arts, the occult and the twilight zones of hard to explain phenomena when solving crimes but this case, where people appear to be literally walking out from the long ago past to rid the world of corporate executives and lobbyists, tops them all.

Henne's List is a rollicking tale that traverses time and continents with regularity as Delmar and his unusual Interpol sidekick, Henne Forren, begin to discover worlds that force them to confront not only the wild actors that these parrallel universes present to them but to confront their own ideas about who they themselves really are.
