When four intrepid children and their faithful dog visit an aunt in Hampshire for the holidays, they are expecting a quiet time wandering the hills and observing the locals. Little do they know they are about to get embroiled in mystery-solving, crime-fighting and doing down some dastardly wrong’uns.

Can they save the day, fuelled only by a hamper of sausage rolls, cheese sandwiches and lashings of ginger beer. Join us to find out.
