Ghosts of Columbia

Now for the first time in one big volume, two complete novels of Dr. Johan Eschbach, professor at a small college in the northeast and secret agent for the government of Columbia. There is no USA, and Columbia shares the continent with Quebec, New France (Medico), Deseret, and Russia (in Alaska). It is an alternate history, reality shaped by the fact that ghosts are not mere superstitions, but have a literal physical reality - and political implications - because crimes can haunt, and the ghosts of crimes are visible to others.
