Some streets have their own personality - Beale Street in Memphis, Bourbon Street in New Orleans - and in Welllington, that haven of Bohemians, Aro Street. A mystery about mathematics, labyrinths, giants and reality is how Danyl McLauchlan describes his latest novel, Mysterious Mysteries of the Aro Valley. Three years ago Danyl published Unspeakable Secrets of the Aro Valley - which also blends mystery and comedy in a characterful Wellington suburb.
