Brian Jessel, a civil servant in the Cabinet Office, is asked to investigate the mysterious death of the civil servant Stephen Summerchild twenty years earlier. Summerchild was working on a Cabinet project, under the Oxford philosophy don Elizabeth Serafin, to find the "quality of life" in Britain. Jessel finds a box of audio tapes from the project containing all the discussions up to the time Summerchild fell off the Admiralty Building.
