The Pericles Commission

The first book of what seems to be intended as a series, THE PERICLES COMMISSION starts out with potential.  I can't remember any other book of this style that I've read that combines series, with a real sense of humour.  It's making Ancient Athens seem like a real place.

From the Blurb:

Athens, 461BC.  A dead man falls from the sky, landing at the feet of a surprised Nicolaos.

It doesn't normally rain corpses.  This one is the politician Ephialtes, who only days before had turned Athens into a democracy.
