In the final episode of the series, Paul heads off in search of the fascinating and unanticipated, discovering Kent's tales of the unexpected.  And his first stop is a real escape into the unknown where he encounters most extraordinary sight – the Red Sand Sea Forts.  Built 13 miles out to sea in the Thames Estuary, these eerie looking WWII anti-aircraft towers proved a great success helping to deter and report incoming German air raids.  Now a rusty relic to the war, Paul is bowled over by this unique monument to Kent's brave history he never knew existed before.
