Hello - thought you might like this long read piece by the excellent Louise Perry in Standpoint mag. She's covered what we've found on these (now 50) cases of men claiming "sex game gone wrong" in the death of a woman or girl at We Can't Consent To This. She's also spoken with legal experts on this like Susan Edwards, as well as the BDSM campaigners at The Spanner Trust.

And
to all of you mumsnetters who helped me find these women's stories.
