William, Mary and Alice Constant have come to spend Christmas with their uncle as their parents are working abroad. Little by little, they discover that things in this remote old house are not quite what they seem. There are powerful forces at work, calling to the children from across the centuries; forces that pull them up the hidden steps in the chimney to the secret room where the magician lives.
