Today he's only a footnote in a shameful period in America's history.

But in the 1950s and 1960s Harvey Matusow was known as "America's most notorious liar".

Constructed with the help of The University Of Sussex's extensive Matusow archive, Robert Cohen brought this complex man to life as a likeable wisecracking loudmouth from The Bronx.

A former Communist Party member, Matusow's infamy came when he began denouncing his former comrades to the authorities during the McCarthy era - often through false evidence.

Only a few years later he bit the hand that had fed him with a confessional autobiography, which revealed the extent of his lies and earned him a five-year stretch in jail.

This one-man show was set during the time he spent in the UK, with Matusow telling his story over the course of seven years, while at the same time venturing into the world of experimental music, with his fifth wife (or sixth, he had problems remembering himself).

He expressed his longing to be forgiven in his homeland, and tried to justify ratting out his friends on both sides of the fence as a crusader trying to expose the scandal of paid testimony - while seemingly choosing never to acknowledge the damage he had done to people's lives.

It was a fascinating story of both the man and the paranoid country desperately looking for enemies within.

With so much material available it was easy to see why the piece lasted 90 minutes, although the nine different scenes ensured that it didn't feel like a marathon for the audience.
