Intertwined caves

Icy, labyrinthine corridors, walls reflecting torchlight in eerie ways. Three corpses on the floor: Remugle, Mildred (the employee of the month's famous sidekicks) and what looks like the employee of the month, decapitated.

→ Remugle. A cruddy but likable bugbear: stabbed in the back between vertebrae.
→ Mildred. A reckless and stubborn amazon: slit throat.
→ Employee of the month. The head has been neatly cut off, but is nowhere to be found. Same species as the employee of the month, wearing their clothes and equipment. Without closer examination, the hosts may conclude they have found them.
→ Closer examination:

• The clothes look a little tight in some places and are not bloodstained, even around the neck.
• The corpse is a little colder and stiffer than the other two.

Note: If one of the hosts has a positive relationship with the employee of the month, they may remember a physical detail (a tattoo between the shoulder blades, a sixth toe on the left foot, a scar on the abdomen, etc.). It isn't on the body.
