Olive Bright

Though war rages across mainland Europe and London is strafed by German aircraft, the little village of Pipley in Hertfordshire bustles along much as it always has. Adrift since her best friend, George, joined the Royal Air Force, 22-year-old Olive Bright fills her days by helping at her father's veterinary practice and tending to her beloved racing pigeons. Desperate to do her bit, Olive hopes that the National Pigeon Service will enlist Bright Lofts' expertise and use their highly trained birds to deliver critical, coded messages for His Majesty's Forces.

Returning to Pipley following her FANY (First Aid Nursing Yeomanry) training, Olive is eager to step up her involvement in the war effort. Her pigeons are being conscripted to aid the Belgian resistance, and it’s up to Olive to choose the best birds for the mission. To protect the secrecy of their work, she must also continue the ruse of being romantically involved with her superior. But perhaps the greatest challenge of all comes when an instructor at Station XVII, the top-secret training school housed at Brickendonbury Manor, is found dead in Balls Wood by a troop of Girl Guides.

As the weather turns bitterly cold in the dark days of November 1941, fewer pigeons are being conscripted for missions into occupied Europe and Olive fears her covert program may be dropped altogether. In fact, the new CO of the Baker Street intelligence operation at Brickendonbury Manor, Major Blighty, has expressed his doubts regarding her birds—not to mention Olive herself—and assigned her to a far more insignificant role: escort to a visiting officer of the Royal Navy Intelligence Special Branch.
