While Serenely Mounting a Ladder

After a solid many months of slackness, I'm back heavy into the introduce the world to Bob Doss project, and, one of my co-conspirators, the lovely LMW says:

Huh.  That's a weird opening sentence.

I respond:

Huh?

She reads:

Yesterday, while serenely mounting a ladder in the furnace room of the parsonage to change a light fixture...

And then she stops.  And decides it's a good mystery.  And a exceptionally excellent use of the word serenely.

And now I (and you) wonder what might follow...

My guess is that it involves an unexpected animal, hopefully a snake.
