Recruited as a codebreaker of enemy ciphers, ex-dubante Osla Kendall spends her days translating Axis military messages and her nights reading mystery novels. When Osla gets her hand on Agatha Christie's most recent work, N or M?, a mysterious signal within its pages catches her eye, and she and her eccentric book club get in touch with the famous but reclusive writer. Osla's outreach is a welcome distraction for Agatha, who feels restless and underestimated toiling away in a London pharmacy while men like her husband can contribute to the war effort from the frontlines.
