Jeffrey Archer

After leaving Oxford he was elected to the Greater London Council, and three years later at the age of 29, he became Member of Parliament for Louth. After five years in the Commons and a promising political career ahead of him, he invested heavily in a Canadian company called Aquablast, on the advice of the Bank of Boston. The company went into liquidation, and three directors were later sent to jail for fraud. Left with debts of £427,727, and on the brink of bankruptcy, he resigned from the House of Commons.

Aged 34, determined to repay his creditors in full, he sat down to write his first novel Not a Penny More, Not a Penny Less. Written at the home of his former Oxford Principal, it was taken up by the Literary Agent, Debbie Owen, and sold to 17 countries within a year. It was also made into a successful serial for BBC Radio 4, and was later televised in 1990 by the BBC.
