The collaborative media outlet svobodnoslovo.com writes [bg] about a new book by Lyubomir Levchev [bg], who mentions Lyudmila Jivkova's death 30 years ago. It has always been reported that Jivkova, the daughter of Bulgaria's last communist dictator, died in a car accident. Levchev explains, however, that she might have been poisoned: he writes about a ring with a turquoise stone Jivkova used to wear that had started whitening a few months before she died. This property has been known [fr] since the Antiquity as a sign of poison in the body.
