Some secrets are just too dangerous to know... Step back in time with this gripping World War II tale with soaring Spitfires and daring liars, from master middle grade storyteller Helen Peters - perfect for 9+ readers!

When Sidney’s school is evacuated to a huge stately home in the countryside, she thinks she’ll be bored. At least her brother must be having fun, flying his Spitfire all over France!

But in the dead of night she sees something being smuggled into the stables. The Earl is having clandestine meetings. And the house is full of secret passageways...

Something sinister is going on, and it’s up to Sidney and her reluctant ally, housemaid Nancy, to uncover the perilous plot. The course of history itself depends on it.

About Helen Peters:

Helen grew up on an old-fashioned farm in Sussex, surrounded by family, animals and mud. She spent most of her childhood reading stories and putting on plays in a tumbledown shed that she and her friends turned into a theatre. After university, she became an English and Drama teacher. Helen lives in Brighton with her two children, two cats, two guinea pigs and one husband.

She writes the Jasmine Green series for young animal lovers, and her other books include Anna at War and The Secret Hen House Theatre, which was shortlisted for the  Waterstones Children’s Book Prize. You can find her on Twitter at @FarmGirlWriter.
