I had a lot of fun taking part in a virtual head-to-head with the historical crime writer Michael Gregorio over on the Crimeculture website. Actually, it was a head-to-head-to-head, because Michael Gregorio is actually two people, the husband and wife writing team of Michael Jacob and Daniela de Gregorio. My thanks to Kate Horsley at Crimeculture and thanks also to Jenn Ashworth, who made it happen.
