What is the author's style in The Long Dark Tea-time of the Soul by Douglas Adams?

The book is divided into thirty-five short chapters. In general, every other chapter focuses on what is happening to either Dirk or Kate. One chapter will be about Kate, and just when the reader is wondering what comes next, there is a chapter about Dirk. The chapters often end cliff-hanger style, by hinting that some momentous event is about to begin but not telling what that life-changing event will be. This increases the sense of trying to solve a mystery, little by little, and it also makes the reader wonder what amazing thing the main character has just remembered.
