Roll up, roll up for the Season Four closer — as we take a trip to the circus!

At Trapped History, we look at lives and stories which have been forgotten or ignored, and there is one community in Britain which is still shrouded in mystery even in the 21st century: that of the circus people. So who better to lift the curtain than the King of the Ring himself, Zippo the Clown — or just plain Martin Burton to us.

Not only does Martin shine a light on the lure of the circus but he also joins us on a journey back in time, when America was in thrall to the greatest showman of all — Frank Bostock, the Animal King from Darlington. Frank's is an astonishing story and an amazing life, which tells us so much about the glory years at the turn of the 20th century when technology, travel and theatre collided to create the magical potion of 'Spectacle'.
