Yup I know similar cases where it's gone fatally wrong - there was one in Stockholm a few years back where a man had been doing some s/m play together with a girl he'd seen a few times before. He was submissive and allowed himself to be tied to a chair, hands cuffed behind and then she would Domme him. Probably the idea was humiliation through words and some slight spanking but they were both quite a bit drunk and it spiralled out of control; she fetched two big knives and stabbed him in the chest, and then tried to cover her tracks by arranging a fire in the apartment. She ended up with a lifetime jail sentence for murder.
Also, it's really important to see that what's "possible" in a story is often way beyond what works in reality. In an abduction story a sub can hang by her wrists for days, her mouth stuffed with a gag, and take masses of flogging. Umm, wouldn't work too good in real life...
