Chimera wall borer

Do you ever dread case-less hotel pillows, and sheet-less hotel beds? The cleaning lady took the old ones yesterday, but did not replace with the new. So, last night, through microscopic bug bites to the head and legs I felt connected to the walls of the building like an instrument through an amplifier. Every goings-on in Sheriff hall was passed through me, as if I were the new night shift. Hums, drums, groans and moans--with the occasional cautious routing about of a mouse--kept me aware of the twilight about me.

Eventually, I started dreaming I was a bug, and could bore through walls at such a speed that I was able to accumulate enough information about wall structures, and probability, that I was then able to see through walls with X-ray precision. Kind of like a character in a childhood book who could see through the very first thing that met his eyes, and everything beyond stood clearly.

I don't remember the title that book, but I think it involved a boy or anthropomorphic pig, a magical phone booth, and some kind of eternal Time Keeper who may have been a talking frog.
