Part of the Mavenhill Classics series, this annotated edition of Agatha Christie's The Secret Adversary pairs a fast-paced early thriller with clear, chapter-by-chapter summaries that guide readers through its shifting identities, hidden motives and political intrigue. In postwar London, opportunity is scarce and certainty even scarcer. Tommy Beresford and Prudence “Tuppence” Cowley are young, clever and restless, determined to carve out a future in a society still unsettled by conflict. When a chance encounter draws them into the search for a missing document of national importance, their pursuit of excitement turns into a dangerous game of deception.
