Dirk Gently is a detective - well, a sort of detective. There is a long and honourable tradition of great detectives and Dirk Gently does not belong to it. Sherlock Holmes observed that once you have eliminated the impossible, then whatever remains, however improbable, must be the truth. Dirk Gently, however, does not like to eliminate the impossible.In Dirk Gently's Holistic Detective Agency a simple search for a missing cat reveals two ghosts, a dodo, an Electric Monk, the devastating secret that lies behind the whole of human history and threatens to bring it to a premature close, and, finally, the utterly terrifying reason why Richard MacDuff has had a sofa stuck on his stairs for three weeks.As The Long Dark Tea-Time of the Soul opens a passenger check-in desk at Terminal Two, Heathrow Airport, shoots up through the roof engulfed in a ball of orange flame. The usual people try to claim responsibility. However, no rational cause can be found for the explosion - it was simply designated an act of God. But, thinks Dirk Gently, which God? And why? What God would be hanging around Terminal Two of Heathrow Airport trying to catch the 15.37 to Oslo?

What do a dead cat, a computer whizz-kid, an electric monk, quantum mechanics, a chronologit over 200 years old, Samuel Taylor Coleridge, and pizza have in common? Apparently not much, until Dirk Gently begins his investigation.
