I had never heard this, and it seems extraordinary to me that I hadn't, given how massive the cultural presence of his books has been recently.
I haven't actually read them; I haven't seen the film (films?) either. Just clicked on this Radfem Hub article and it has left me 
. What do you all think? Has it been discussed before? (I searched "larsson rape" but didn't see anything) Do you think it is likely to be true, or (as suggested in comments to the linked post) more likely that he made it up as a convenient PR "angle"? Either way seems horribly exploitative and troubling.
