Dirk Gently is a BBC TV series inspired by the Dirk Gently books written by Douglas Adams, adapted for television by Howard Overman. It stars Stephen Mangan as Dirk Gently, an eccentric detective who operates according to a holistic principle he calls 'the fundamental interconnectedness of all things' -- namely, that since everything is somehow linked together, then anything he does will bring him closer towards solving the mystery, meaning he can theoretically do anything and solve the case -- and get paid for it.
