The King's Man. The Zero Enigma, #7

The City of Shallot is on the verge of revolution.  The Great Houses are mustering their forces, readying themselves for a shift in the balance of power.  The poor have found a new leader and are - finally - demanding their rights.  Shadowy figures and old ghosts are prowling the streets.  It is only a matter of time before the unease and unrest explodes into violence, as the wealthy and powerful seek to secure themselves in a changing world.  And dark forces are laying plans to take advantage of the chaos ...
A newly-graduated student, the son of a proudly independent merchant, Adam Mortimer is recruited into the Kingsmen and charged with helping to track down the anarchists and terrorists before they trigger an explosion.  But, as he delves into the mystery, he finds himself caught between the scars of his childhood and his hopes for the future, loyalties tested as he finds himself caught between old friends and new.
And, as infernal devices begin to terrorise the city, Adam must risk everything to save the people he loves ...
