Roald Dahl's "The Witches"

""Mr Jenkins came striding up to our table with a very purposeful look on his face... He spoke rudely and looked very angry. My grandmother put on her frostiest look, but didn't answer him.
...
"Where is Bruno? If you don't tell me at once I shall summon the police!" cried Mr Jenkins
"Bruno is a mouse," my grandmother said, calm as ever.
"He most certainly is not a mouse!" shouted Mr Jenkins.
"Oh yes I am!" Bruno said, poking his head up out of the handbag.""
