Talbot is killed in the Falklands Campaign leaving her with her adored step-son Eric, a student at Cambridge. Then Eric dies in Paris of a drug-overdose, and when Sarah seeks to uncover the mysterious circumstances surrounding his death she finds all official roads to justice are blocked. If she wants satisfaction she must take matters into her own hands. And Sarah is determined: someone must pay.When she meets enigmatic young former SAS sergeant Sean Egan, an eloquent lone gun and the ultimate soldier, she knows she has the weapon she needs. A study in contradictions, Egan is a careful, thoughtful man, but a man to whom killing is as natural as breathing.Together they embark on a quest for revenge that will lead them from London to Paris, to Sicily and Northern Ireland, then back to London and a shattering climax on the dark, brooding wharves of the river Thames. Together Sean and Sarah will plumb the depths of the underworld, a world in which man’s capacity for destruction is almost beyond belief, a world in which revenge truly is a “season in hell."
