Saki 
Tooth and Claw — Short Stories Level 3 Oxford Bookworms Library 

A level 3 Oxford Bookworms Library graded readers. Retold for Learners of English by Rosemary Border. Conradin is ten years old. He lives alone with his aunt. He has two big secrets. The first is that he hates his aunt. The second is that he keeps a small, wild animal in the garden shed. The animal has sharp, white teeth, and it loves fresh blood. Every night, Conradin prays to this animal and asks it to do one thing for him, just one thing. This collection of short stories is clever, funny, and shows us ‘Nature, red in tooth and claw’. In other words, it is Saki at his very best.
