The Dinsmead family - pompous father, worn-down mother, and their 3 grown children - moved to a lonely country home rather abruptly upon Mr. Dinsmead's retirement from the building trade. Johnnie is suffering a series of running battles with his father, since he prefers chemistry to building, while his sisters are unhappy at being isolated in a house they think is haunted. Then a stranger (parapsychologist Mortimer Cleveland), stranded for the night by a flat tire, finds a mysterious message written in the dusk beside his bed.
