The TV version is described as a “post-pandemic” contemporary retelling of one of The Night Manager author John le Carré’s most popular novels. The Constant Gardener follows Justin Quayle, a British diplomat and avid horticulturalist who meets an Amnesty International activist in London called Tessa. After striking up a romance, they head on a journey that weaves together a brutal murder, government corruption and corporate malfeasance in a plot which unravels across Kenya, the UK and mainland Europe.
