A man, a woman, and a young girl. ...all three dead.
...but all three still very much alive.

Jude ... who has renamed himself Justice, after the job he has ... is a half-rotted and highly radioactive corpse. He has encyclopedic knowledge, but no memory of who he was.
From her last dead body, Rita transfers to a freshly murdered woman and has to deal with the killer. But she has no control over to whom, to where, or when it happens.
Germaine is a ghost who can only be solid within six feet of Justice or Rita.
Together, they work for a common cause. ...bringing the monsters ... the real monsters ... to answer for their crimes.
While the Horsemen of the Apocalypse are the ax, Rita and Justice ... the Horseless Horsemen ... are the scalpel.
