I am surprised that some reviewers saw humor in this book, I did not, not at all
The " Cleaner" seemed dangerous due to her delusions about the people she cleaned up after.
Her psychosis could very well, In real life, have turned deadly
Spraying someones ciggeretts with disinfectant or mixing laxatives into someone's powdered protein borders on homicidal.
Nowhere in the book does anyone call her out on her actions or offer to help.
I found the book boring, disturbing and unrealistic
