The Wind Through the Keyhole fits into the Dark Tower series between book four and five when Roland and his Ka-tet are forced to take shelter from a storm. While waiting the storm out Roland tells a tale from his past where he and Jamie DeCurry are sent to investigate some murders that involve a shape shifter called a skin-man. During this tale Roland tells the tale of “The Wind Through the Keyhole” to a scared child just as his mother did for him when he was a child. This addition to the Dark Tower series does not affect the story in the other seven books but instead adds a little insight to Roland’s past and Midworld itself. Though not an essential story to the Dark Tower, it is a short fun read for any fan of the Dark Tower series and is also written well enough that readers do not need to read the first four books to enjoy it!
