Question: Call a spade a spade has been used in literary works by what British playwright, novelist, and short story writer who was reportedly the highest-paid author during the 1930s?
Sentence (from "Call a spade a spade"): The idiom originates in the classical Greek of Plutarch's "Apophthegmata Laconica," and was introduced into the English language in 1542 in Nicolas Udall's translation of the "Apophthegmes," where Erasmus had seemingly replaced Plutarch's images of "trough" and "fig" with the more familiar "spade."
