"G-r-r-r...!" by Robert Donald Locke is a short story written in the mid-20th century, known for its comedic and fantastical elements. The plot revolves around a conflict between two monks, Brother Ambrose and Brother Lorenzo, set within a cloistered monastery. The story explores themes of jealousy, revenge, and the consequences of one's actions through the lens of supernatural occurrences. In this tale, Brother Ambrose, filled with loathing for the seemingly pious Brother Lorenzo, discovers an ancient manuscript titled "De Necromantiae", which contains a spell that purportedly allows a man to transform into a werewolf. Driven by his intense hatred, Ambrose seeks to use the spell to exact his revenge. However, in a twist of fate, his poor understanding of the incantation results in his transformation into a flea instead. This inadvertent change leads to a humorous climax when Brother Lorenzo innocently swats him, underlining the futility of Ambrose's vengeful plan and leaving readers amused by the absurdity of the situation.
