Appropriately enough, this two-hour tour begins at Whitechapel's Blind Beggar pub, a favourite haunt of the infamous Kray brothers and their gangster cohorts. And even more appropriately, it's led by onscreen hardman Stephen Marcus, best known for his role as Nick the Greek in Guy Richie's modern-day gangster flick 'Lock, Stock and Two Smoking Barrels'. As well as leading participants to various Kray-related sites in the area, Marcus will also relate accounts of other London gangsters and take part in a a Q&A, photo and autograph session.
