5 volumes1922–1973Completed
- Christie’s lighter, adventurous pair, who age in real time: they start as broke young friends after the First World War in The Secret Adversary (1922) and are retired grandparents in Postern of Fate (1973), the last novel she wrote.
- The books are spy capers more than puzzles.
- Start with The Secret Adversary, the most read; N or M?, a Second World War spy hunt, rates a little lower.
