For twenty-five years I ran my own anti-money laundering consultancy, which gave me almost limitless opportunity to write about my very favourite subject: money laundering. And the obsession with understanding the mechanics and motivations of financial crime has only grown.

I have spent years haunting the streets of Regency London, in the company of magistrates' constable Sam Plank. He is the narrator of my series of seven historical financial crime novels set in consecutive years in the 1820s - just before Victoria came to the throne, and in the policing period after the Bow Street Runners and before the Metropolitan Police.

The fourth Sam Plank novel - "Portraits of Pretence" - was given the "Book of the Year 2017" award by influential book review website Discovering Diamonds. And the fifth - "Faith, Hope and Trickery" - was shortlisted for the Selfies Award 2019.

And I have just published the first in a new series of five books set in Cambridge in the 1820s, narrated by a university constable called Gregory Hardiman.
