Dirk Gently’s Holistic Detective Agency solves the whole crime and Dirk is on this case involving ghosts, time travel and a mission to save humanity. I’ve been meaning to read this book for awhile since I happen to love The Hitchhiker’s series. This novel does not disappoint. It is thoroughly science fiction comedy and a unique read. Clever, ridiculous, eccentric, in other words, deliciously Douglas Adams.
