Spring 1915: World War One rages across Europe. Amidst this bloodbath of nations, where one man’s flag is another man’s shroud, a British spy is asked to do the impossible: seduce and betray the woman he loves, again. Only this time betrayal is a two-way street.

 

Jack McColl, a spy for His Majesty’s Secret Service, is stationed in India and charged with defending the Empire against Bengali terrorists and their German allies. In England, meanwhile, radical journalist Caitlin Hanley begins rebuilding her life after the execution of her brother—an IRA sympathizer whose terrorist plot was foiled by Caitlin’s own ex-lover, the very same Jack McColl. The war is changing everything and giving fresh impulse to the causes Caitlin has long supported. The threat of a rising in Dublin alarms McColl’s bosses as much as it dazzles Caitlin. If another Irish plot brings them back together, will it be as enemies or lovers?

 

“As a spy thriller, as a love story, and as vibrant historical re-creation, this one hits on all cylinders. Thankfully, the series is still in its early days.”—BOOKLIST, STARRED REVIEW ON ONE MAN'S FLAG
