The fourth of Allan Ahlberg's mini-masterpieces for early readers. In this thrilling, thunderous (and extra-long) Gaskitt story, Mrs Gaskitt finds a parcel, Mr Gaskitt loses a baby, Horace has mixed feelings about a bird, and the twins' teacher, Mrs Fritter, is - ooer! - not herself. Why? How? When? Why? (again). The children smell a rat!
