Very entertaining. Translated from Swedish.

Don’t let her age fool you. Maud may be nearly ninety, but if you cross her, this elderly lady is more sinister than sweet. 

I’ve never cheered a homicidal lady more. 😀

En route to a luxury vacation in South Africa, Maud recalls half a dozen earlier times when her generally untroubled life was threatened by someone who ended up coming to grief. …

A guidebook to growing old without a single regret for victims who deserved just what they got.
