And will it ever end?

Too much is at stake and the players far too committed for there to be an easy solution. Tracks must be covered at any price but there are always traces. John Adamson and Anna find the way to the heart of an organisation intent on spreading mayhem and destruction. For them there can be no compromise with the past - or a future without justice.

In the end even Anna is surprised by what she brings into the light of day. The impact reaches far beyond her original personal mission and for once there is not just a fatal sting in the tail from this Scorpio, quite the reverse.
