The year 1790 & England is on the cusp of war with Revolutionary France. The night-time Channel is the scene of intense smuggling activity & the passage of spies from one coast to another. Lieutenant James Hayter has achieved his heart's desire
- his first independent command His Majesty's ' Hawk' cutter 10 guns. She is swift enough to out sail even the fastest of the French contraband runners & she is Hayter's pride & joy. But his happiness is tempered by the knowledge that his former captain & friend William Rennie has been left on the beach after the failure of the Rabhet expedition the previous year. But it is not long before spymaster Sir Robert Greer disturbs Rennie's imposed retirement with a sinister & irrefutable offer that will see Rennie hastening to join his former subordinate in Portsmouth. Together they will have to tackle one of the most sensitive & dangerous missions of the phoney war to intercept a contraband runner the cutter ' Lark' & capture her captain a disgraced Navy lieutenant. But as with all matters orchestrated by Greer the mission is about a lot more than capturing a few barrels of brandy & a wanted criminal. In fact it is soon evident that the very security of the nation depends on Rennie & Hayter's success.
