A real dagger - not a prop - Is used against the director of a medieval theater troupe.

Actor and stage director Renan Thomas is stabbed when he is playing in The Legend of Knights, a medieval spectacle in Provins. Karine Demarle and her son are witnesses of this intent of murder committed by a disguised person. By chance the help comes soon and Renan's life is saved. Patrick Robin and his ex-wife Karine Demarle will be in charge of this case of criminal investigation.—zutterjp48
