Dr Mark Vincent is an accomplished and confident speaker whose work focuses on Russian true crime from the 18th century to the present. He has a book on criminal gangs in the Stalinist Gulag which will be published by Bloomsbury in late 2019. There is a link to the pre-order and more info here:
More of Mark's writing is available at https://cultoftheurka.wordpress.com/. This site has some short pieces about Russian bandits, super-thieves & famous court cases, some of which I'll be talking about in my upcoming Funzing events.
For any further information, he is @VincentCriminal on Twitter or you can get hold of him through the blog site.
