Traitor's Blade: the swashbuckling start of the Greatcoats Quartet

Book 101 Review

The Three Musketeers meets Joe Abercrombie via Mark Lawrence: 'Guaranteed to increase household swashbuckling by 100%,' says Library Journal
The Greatcoats are travelling magistrates bringing justice to all . . . or at least they were, before they watched the Dukes impale their King's head on a spike. Now the land's heroes are reviled as traitors, their Greatcoats in tatters.
Facio, Kest and Brasti have been reduced to working as mercenaries, but when they find their employer dead - and are forced to watch as the killer plants evidence framing them for the murder - they realise things are about to get even worse.
