Alex Gerlis was a BBC journalist for nearly thirty years and is the author of fourteen Second World war espionage thrillers, all published by Canelo.

His first four novels are in the acclaimed Spy Masters series, including the best-selling The Best of Our Spies which is currently being developed as a television series. Prince of Spies was published in March 2020 and was followed by three more in the Prince series. The Wolf Pack novels, which began with Agent in Berlin, first published in November 2021. His most recent series is the Double Agent series, beginning with Every Spy a Traitor.

Alex was born in Lincolnshire and now lives in west London with his wife and two black cats, a breed which makes cameo appearances in all his books. Alex has two daughters and two grandsons and supports Grimsby Town, which he believes helps him cope with the highs and especially the lows of writing a novel. He's frequently asked if he's ever worked for an intelligence agency but always declines to answer the question in the hope that someone may believe he actually has.
