You gingerly pick at the clothes, fearing that the substance may be acidic. As you pick up the topmost item of clothing, your brain helpfully supplies that the liquid is blood, and that it isn't harmful unless you ingest it. You find this odd, as the substance is brown or possibly a very dirty dark red. That's not how you remember blood. Examining the pile you note something interesting. The clothes have not been folded, but are lying in a pile. There is still some sort of order in the pile. Topmost is a lab coat, shirt still inside it. Underneath that there is a pair of pants with underwear still inside. At the bottom of the heap lies a pair of shoes, with socks inside them. The white lab coat is stained with brown "blood", but the tan clothes underneath are as pristine as your own, and smell of the same lemon conditioner. The clothes feel quite warm, as if they had been recently worn.
The clothes definitely belong to a petite female and are several sizes too small for you. This realisation sends a pang of anguish up your spine, as you realize that these are the sort of clothes you could wear too if you weren't stuck in this grotesque body.
Rifling through the pockets you find a key card and an identity card. The identity card is simple, containing only a picture of a smiling woman and a bar code. More worrying is what you find beside the pile of clothes, obscured by the lab coat. It appears to be a sharp instrument of some sort, slightly similar to a scalpel. The blade is mottled with dark brown. This weapon has recently been used.
Unsettled by this and lacking anywhere to put these items, you pick up the cards with one hand, and the knife with the other. You carefully approach the door numbered 8, and peer in through it.
The room is the same size as yours, and the walls appear to be made of the same material. Whoever lived here really didn't like them though, in many places the spongy material has been ripped out or torn to pieces, exposing white tiles behind it. Close to the door, a small shape lies in a crumpled heap. The shape is lying in a large puddle of brown "blood", some of which has been slowly running towards the door.
What now?
