Spring be springing’ as it's wont to do, so the ladies of the Nightmare Cottage wax a little more cottagecore than usual as they gush about their gardens.

Whatever. Nylene follows that up with a bit of history on one of the rare (relatively speaking) English serial killers, John George Haigh… the Acid Bath Killer.
