This really is the ultimate answer to Life, the Universe and Everything
All five radio series of The Hitchhiker's Guide to the Galaxy collected together for the first time, in a handsome box with magnetic lid.
From the original Primary and Secondary Phases, through to the more recent Tertiary, Quandary and Quintessential Phases, these are the adventures of Arthur Dent, Ford Prefect, Zaphod Beeblebrox and their assorted human, robotic and alien companions.

These full-cast BBC Radio 4 dramas star Simon Jones, Peter Jones, Geoffrey McGivern, Mark Wing-Davey, Stephen Moore and Susan Sheridan, with a stellar guest cast including John le Mesurier, Joanna Lumley, Christian Slater, Jackie Mason, Sandra Dickinson, Rula Lenska, Griff Rhys Jones and Jonathan Pryce.

Also included is an exclusive bonus disc containing two programmes from the BBC Archive: Kaleidoscope from 1980 (going behind the scenes of the second series) and Six Characters in Search of an Answer: Arthur Dent from 2002.
