Penelope Wicket is a character who thinks she is always right and correct and she has no problem with telling people how they should live. She is also not afraid to take action to make things match her world view or to mete out justice. For better or for worse.
In The Sinner's Wealth, a short story, Penelope visits her only living relative, a cousin, in a nursing home in Denver. While there, she learns about a thief on the staff as well as the personal wealth of her cousin.
While she does profit from the events that result from her own little twist to this knowledge, they are not really her fault. She can't be expected to control other people's larcenous behaviors, now can she?
