Redheaded John’s room was full of rats: he used to catch them in big gins, and then let them go for Tabby to despatch. Once the cat was so impatient he seized trap and all and caterwauled off into the night banging it on the stones and sending up showers of sparks. Again he returned in a few days, very sleek and pleased: but John never saw his trap again. Another plague of his were the bats, which also infested his room in hundreds. Mr. Bas-Thornton could crack a stockwhip, and used to kill a bat on the wing with it most neatly. But the din this made in that little box of a room at midnight was infernal: earsplitting cracks, and the air already full of the tiny penetrating squeaks of the vermin.
