"When the Beresfords obtain an old house and its contents, Tuppence discovers a series of underlinings in a copy of The Black Arrow. When she writes down the letters, they spell out a very disturbing message: "Mary Jordan did not die naturally." After sixty years, Mary Jordan's enemies are still ready to kill"--

Set during the dark days of World War II, Agatha Christie’s N or M? puts two most unlikely espionage agents, Tommy and Tuppence Beresford, on the trail of a pair of Nazi spies who have murdered Britain’s top agent. World War II is raging, and while the RAF struggles to keep the Luftwaffe at bay, Britain faces a sinister threat from “the enemy within”—Nazis posing as ordinary citizens. With pressure mounting, the intelligence service appoints two improbable spies, Tommy and Tuppence Beresford. Their mission: to seek out a man and a woman from among the colorful guests at Sans Souci, a seaside hotel. But this assignment is far from an easy stroll along the promenade—N and M have just murdered Britain’s finest agent and no one can be trusted.

The complete eBook collection of all five Tommy & Tuppence mysteries by the Queen of Mystery herself, Agatha Christie, including The Secret Adversary, Partners in Crime, N or M?, By the Pricking of My Thumbs, and Postern of Fate.

A classic Agatha Christie short story, available individually for the first time as an ebook.

Doctor Haydock, the resident GP of St. Mary Mead, hopes to cheer up Miss Marple as she recovers from the flu with a little story. The tale revolves around the return of the prodigal son of Major Laxton, the devilishly handsome Harry Laxton. Harry, after leading a life of childish indiscretions and falling head over heels for the village tobacconist’s daughter, has made good and returned to lay claim to his tumbling childhood home and introduce the village to his beautiful new wife. But, the villagers are prone to gossip about young Harry’s past, and one person in particular cannot forgive him for tearing down the old house. Will Miss Marple’s acumen be up to the task of solving the story?
