Following The Railway Children, Lionel Jeffries created this equally magical and much-loved classic. A mysterious and kindly old solicitor called Mr Blunden pays a visit to recently widowed Mrs Allen and her children offering her the position of caretaker at a derelict country mansion. Struggling in their cramped London flat they cannot refuse and soon arrive at their new home. More surprises are in store when the children not only encounter the ghosts of two previous young residents but also find themselves going back in time to help them righta 100-year-old wrong. Tricia's husband Daniel has been missing for seven years. Her younger sister Callie comes to live with her and helps her find the strength to finally declare him legally dead ‘in absentia’. As Tricia tries to move on with her life she is haunted by terrifying visions while her sister finds herself drawn to an ominous tunnel near the house which is linked to other unexplained disappearances. It becomes clear the tunnel holds a dark secret, something lies in the shadows and Daniel may be suffering a fate far worse than death.
