A Key Outcome

I geared up for a major expedition. Gathered a tote bag for knife, torch, gaffer tape and should have had a breathing mask. Yes I was going under the house. Go back two days though, to our bathroom where I took a towel off the door knob which flicked the door key out of the lock and pirouetted it neatly through the bars in the floor grill. The key entered at speed and came to rest two metres down the tube.  Underneath, after winding through a maze of tubes, wires and cables I reached the target.  Slicing through at the lowest point, there was a flood of dirt, lathen plaster rubble and debris. This had been lying in there and wafting dust upward with the warm air for years but I did get the key out.

Now this key has two locks
