Holier Than Thou

Constantine Grey is a Canadian-born author and former international banking executive whose life has taken him from boardrooms in New York and London to high-stakes meetings in Moscow and Istanbul. A graduate of Queen’s University and a Chartered Professional Accountant, Grey rose to Vice President at the National Bank of Canada, leading real estate lending across North America. His global career included a year living across from the Kremlin—culminating in a private dinner with President Boris Yeltsin.

Fluent in English, Greek, French, and German, and conversant in Russian and Serbian, Grey brings a rare international depth to his work. His debut book, Holier Than Thou, takes a bold and thoughtful look at the roots of radical Islamist violence. Rather than condemning from the outside, Grey engages from within—challenging extremist ideologies through rigorous thought, moral clarity, and a call for honest dialogue.

Rooted in global experience and driven by a belief in reason over fear, Holier Than Thou is a timely, courageous debut from a writer who has seen the world—and is unafraid to confront its hardest truths.
