The UK has produced a lot more world-renowned serial killers than France has. And they make just as good a tourist attraction as royals. (The jobs have sometimes been combined, but Dennis Nilsen was a lot easier on the public purse than Henry VIII).

Jack the Ripper already has themed tours, but think of the other possibilities. Parades of white vans on Robert Black Day. Community garden- and cellar-digging parties to commemorate the Wests. A new dance introduced by celebrity singers for Bible John.
