Early in the morning, while the Moodey Building sleeps, a man is shouting at the caretaker. He thinks no else will hear him - but he hasn’t reckoned with Hazel Green! She can hardly believe the awful things she hears - or who is saying them.

‘Yakov,’ announced Hazel to the Yak, ‘we have to teach him a lesson. I’ve got the perfect plan, and I’m giving you the chance to help.’

But Hazel’s plan isn’t perfect. When it backfires, Hazel finds that she’s the villain! It will take all her courage and determination, as well as some help from the Yak, to prove what really happened.

Hazel Green is at her irrepressible best in another funny, captivating story from acclaimed author Odo Hirsch.
