Bagless

I had intended to merely eat my bonds, work my way free of the sack, and re-enter it before anyone was the wiser.

It was a dumb plan; once free of the rope, the sack went directly into one of my stomachs.

I'd also been planning to go out the window; that was high against the roof (I could easily leap to it) and had a metal grillwork.

So... door.

I'd had a variety of sticks and stones and herbs, but only the stones had survived my need for biomass, for nutrition. None of them were thin and wiry, the sort of tool one could pick a lock with. I went to fiddle with the lock, only to discover that the keyhole was on the other side.

I knew nobody cared if I screamed, so I did. That had all the effect on the door someone would expect. Probably for the best, though. Even if I unlocked it, the guard or guards on the outside would just kick the door into my face...

Into my face.

The door opened inward.

The hinges were on my side of the door.
