Born in Scotland, Douglas was brought up in England and became a London based international lawyer, later living and practising in the USA. In tandem, he developed a successful career as an internationally read author of mystery thrillers and non-fiction with a chart-topper, an Amazon Best Book of 2014 (and now 2015) and a WH Smith Paperback of the Week to his credit. After originally adopting the pen-name Cameron Ross, he now writes under his own name. The series of books written under the name Cameron Ross are now going to be available shortly as e-books but under the name of Douglas Stewart. He has also published as Brett Morton. He is married with three children.
