The Wind Through the Keyhole is a perfect bridge between the fourth and fifth novels in Stephen King's epic masterpiece. A story within a story that features both the younger and older gunslinger, it is also a wonderful introduction to The Dark Tower series.
As Roland Deschain and his ka-tet leave the Emerald City, a ferocious storm halts their progress along the Path of the Beam. While they shelter from the stark blast, Roland tells a story about his younger days, when he was sent by his father to investigate evidence of a murderous shape-changer.
At the scene of the crime he had tried to comfort a terrified young boy called Bill Streeter by reciting a story from The Magic Tales of the Eld that his mother used to read to him at bedtime, 'The Wind through the Keyhole'.
