Bulldog Drummond and the Havana Vendetta

When British war hero–turned-adventurer Hugh "Bulldog" Drummond sails to Havana to answer an anonymous summons, he expects a routine intelligence errand. Instead, a Royal Navy officer is gunned down on the pier before Drummond can even disembark—clutching a sealed envelope marked STRICTLY CONFIDENTIAL – CALYPSO FILE. From the smoky bars of Old Havana to sugar-refinery ruins, from high-stakes casino tables to jungle strongholds near Santiago, Drummond and the sharp-witted Lucía Ramos follow a trail of assassins, coded ledgers and sabotaged freighters. At the centre of the web lurks Mathilde Vianne — the legendary Crimson Widow, a master spy once thought dead, now orchestrating an arms-smuggling conspiracy designed to fracture the British Empire from within. Facing ambushes on the Malecón, a brutal trap in a derelict theatre, and traitors in London's own corridors of power, Drummond must survive a vendetta that spans oceans—before "Operation Calypso" sparks a war the world isn't ready for. A 30-chapter international thriller steeped in 1930s atmosphere — perfect for fans of classic Bulldog Drummond adventures, high-stakes espionage and noir-tinted historical intrigue.
