Frogs?!

     I goggled. "Doing what?"

    "Strewing frogs. In Constable Dobbs's boudoir. The Vicar suggested it."

    "The Vicar?"

    "I mean it was he who gave Corky the idea. She had been brooding a lot, poor girl, on Dobbs's high-handed behaviour in connection with her dog, and last night the Vicar happened to speak of Pharaoh and all those Plagues he got when he wouldn't let the Children of Israel go. You probably recall the incident? His words started a train of thought. It occurred to Corky that if Dobbs were visited by a Plague of Frogs, it might quite possibly change his heart and make him let Sam Goldwyn go. So she asked me to look in at his cottage and attend to the matter. She said it would please her and be good for Dobbs and would only take a few minutes of my time. She felt that the Plague of Lice might be even more effective, but she is a practical, clear-thinking girl and realized that lice are had to come by, whereas you can find frogs in any hedgerow."
