Buck accepts, then adds a condition of his own: that they prove their skill by operating on unfamiliar machines by switching planes (having learned of his plane's sabotage). The foreign pilot quickly backs down.

- Played for Drama in Judge Dee. The judge is facing a crime that he cannot prove (examinations of the body show no poison and no wounds), so a young woman tells him offhandedly about wives married to abusive husbands, sitting in their rooms repairing their shoes with a hammer and tiny nails, and how easy it is to drive the nail into the skull of a sleeping man... The judge has the body reexamined, finds the nail, and has the victim's wife arrested. The young woman who told him commits suicide to prevent the judge agonizing between his conscience and his duty (she admitted to murdering her husband in front of him, but had every reason to).
- Miriam Allen deFord's short story "Walking Alone". A man calls into work and lies, saying he can't come in that day due to his bad back. He then goes out to the country for a walk.

The girl's body is found and a man is accused of the murder. The protagonist knows that it's the wrong man since he saw the real one, but he still doesn't come forward. The falsely accused man is tried, convicted and executed for the crime, and the protagonist goes mad with guilt.
- In PartnerShip, the five Royal Brats that Nancia ferried to their remote postings in the Nyota system are all planning to use their positions for various kinds of corrupt practices (they even have a bet going; the one who makes the most shady money in five years gets a cut of the others' operations).

- The Judge Dee Fan Sequel "The Chinese judge's survival guide" sees the judge looking for the head of a vast conspiracy to send troublemakers and criminals to an out-of-the-way town when a shopkeeper reports Tao Gan's shoplifting to the local judge. This turns out to be a mistake, since Dee deduces that if the shopkeeper caught Tao (a very good thief), he must be a professional himself. And if he can go and report it without caring that this automatically marks him as a criminal as well, then there is a very good chance the man he's looking for is in the town. He's right.

- The RPG version of Legend of the Five Rings includes several skills that are classified as "Low Skills" such as Forgery, Sleight of Hand, and Temptation, which if you ever exhibit or imply knowledge of, will lead to dishonor.
