From the award-winning author-illustrator of The Black Rabbit, comes the story of Clemmie - a brave, fearsome cat who knows exactly how to catch a mouse. And she would prove it, too, except that she's never actually seen a mouse. Perhaps, she thinks, they're all afraid of her. But wait ... is that a pink tail, or a dangling ribbon? A whiskery nose, or a spider's legs? Kids will love spotting the mischievous mouse dressed up in disguise throughout this adorable picture book, and will root for Clemmie to discover the mouse right under her nose once and for all!
