An atrocity in 1980s El Salvador, when the first Taser hit the streets, building the Delhi metro, exploring Arabia's Empty Quarter and the battle to reclaim a Klimt masterpiece

The woman who risked her life to reveal that the army, not left-wing rebels, were responsible for the murder of six Jesuit priests in 1980s El Salvador; the moment when the Taser first hit the streets; the long legal fight to reclaim Klimt's masterpiece Woman in Gold; the man who got the Delhi metro built; and travels in Arabia with Wilfred Thesiger.
