A new transparency report links Rakhat Aliyev, the former son-in-law of Kazakhstan’s dictator, to a famed Baker Street address in London. Jagshemash, the game’s afoot. The home of the world’s most famous fictional detective may be owned by the deceased No. 2 secret policeman of Kazakhstan. A new deep-dive investigation conducted by the London-based transparency watchdog Global Witness suggests that Rakhat Aliyev, along with his alive and highly influential son Nurali, may be the ultimate legal owners of Sherlock Holmes’s celebrated house at 221b Baker Street—or rather, the site where the house would have been had it existed. (There’s a Sherlock museum carrying that exact address located in the wrong place, a few doors down.)
