The Gold Bomb

All signs point to the strong probability that somewhere in Merrie Old England, someone, for some purpose unknown (but certainly criminal) is building himself an atom bomb!

Obviously, it's a situation that requires the immediate attention of the Avengers – John Steed and Tara King – and they promptly swing into action.

The two search everywhere for clues – from jewelers' shops to a gypsy encampment – at one point the elegant Steed even descends from his stately Bentley to career about the countryside all day on a bicycle!

Time is running out. Can the Avengers find this maniac before he or she blows up half of England?
