Vera: No cartridge firearm (and Vera is obviously one) needs "air around her" to fire. Every cartridge has everything it needs right inside it. Guns can be fired in vacuum, and even underwater. It's been tried and proven. This was just a case of writers not knowing shit about something.
Saffron: Dynamite bod, butterface, IMHO. I know I'm almost alone in this.
The Reviews: I agree with everything Mal wrote above. I'm reading the prose paragraphs and skimming over all the pointless stats.
What does butterface mean?
Old Male Chauvenist Pig saying: "She has a nice body, but her face
ain't that great." The whole sentence shortened to just the code word "butterface."
IMHO, of course.
