Armchair detectives with killer taste, meet your next obsession: can you puzzle out WHO KILLED MARY?

Mary Slater is dead, people. She died in the early hours of today.

The police aren't interested. They are saying no foul play. But let's be clear: Mary was murdered. Do not believe the internet - she was not some unhinged young influencer but a woman needing protection.
