La calle de los espías

What happens when an old spy like David Cartwright loses his mind? Does anyone deal with those agents who hoard classified information, but do not remember what it is? These are some of the questions that his grandson River, a member of the team of Jackson Lamb and his "slow horses", the outlaws of the British secret service, wants to answer now that his grandfather, a Cold War myth and legendary MI5 figure He begins to forget things. For a time, Jackson Lamb worked with the former agent and knows that this is not some helpless octogenarian, but the one responsible for many deaths by omission, sacrifice or direct liquidation. And it is Lamb who is called to identify the lifeless body discovered at David Cartwright's house, while a bomb has exploded in a shopping center and the slow horses of the House of the Swamp must act before everything gets worse.
