Dead Lions

Expendable and incompetent Secret Service agents eventually wash up at Slough House, where they toil on pointless administrative tasks for a foul-mouthed, grubby boss called Jackson Lamb. Lamb is deliciously politically incorrect, offensive, and drinks and smokes to excess in his pit of an office. However he has a keen mind, is an experienced spy, and not afraid to act decisively to protect his employees and society. In this episode he unravels a nest of sleeper agents after an old Cold-War era colleague is found murdered on a coach. The book is well written and neatly plotted.
