The seven young members of the Blue Door Theatre Company are, at long last, professional actors. And they are now proudly in charge of the first commercial theatre in their hometown of Fenchester. But the day-to-day pressures of financing the theatre and choosing box-office attractions are soon eclipsed by an event that threatens to close the theatre almost as soon as it has opened. Following the characters from the classic of children's literature The Swish of the Curtain on an adventure which takes them far from the stage of the Blue Door Theatre, Blue Door Venture is the fourth book in the Blue Door series.

"I wanted to act before I read [The Swish of the Curtain], and afterwards there was no stopping me" - Maggie Smith

"An enchanting book. A must for any child who wants to become an actor" - Eileen Atkins
