Burden, who had served in the war, and had considerable experience of death in its violent forms, took a pace forward. He saw at once that Mr. Wynter was beyond mortal aid. Gregory Wynter is shot dead through the window of his dressing room. There is no apparent motive for the crime, and it seems impossible for the murderer to have escaped before the police arrive. The dead man's brother, Austin, enlists the help of Christopher and Vivienne Perrins, a brother-and-sister team of private investigators. In this classic puzzler, the Perrins piece together the complex relationships within the Wynter household and beyond. What they discover leads surprisingly to romance, not to mention the unravelling of an "impossible" murder which also involves a box of poisoned chocolates . . . Murder at Monk's Barn was originally published in 1931. This new edition features an introduction by crime fiction historian Tony Medawar.

"Would it interest you to discover the identity of the man who boarded the bus at Piccadilly Circus with Lola Martinaes at about ten o'clock last Friday evening?" A woman is found sleeping on a London bus-so deeply asleep, in fact, that she cannot be woken. After being taken to hospital, the woman dies. She is identified as Lola Martinaes, a native of Montedoro-a Central American country whose volatile politics might lead to a world war. There is no apparent evidence of foul play in Lola's death. But the story nonetheless catches the attention of Christopher Perrin, private investigator, especially after he makes the acquaintance of Señor Vincente de Lanate, a Montedorian diplomat. Señor Vincente is certain Lola was murdered and asks Perrin to investigate. More suspicious deaths and disappearances ensue, the sinister circumstances suggesting an international conspiracy. Christopher Perrin soon finds himself playing for the highest stake of all - his life. The Figure of Eight was originally published in 1931. This new edition features an introduction by crime fiction historian Tony Medawar. "A complicated plot, well-developed and well-written." Times Literary Supplement

Herr Berndt leant forward in his chair. "Have you ever noticed how if one speaks about a thing, one usually hears about it again within a few days?" Christopher Perrin, investigator, is on the track of Duggie the Locksmith, suspected of being behind a major robbery. When he is caught in Belgium, Perrin is astonished and puzzled to see in the crowd a certain Maurus Kaulin, "one of the most skilful forgers in existence," whose path Perrin has crossed before. Pike confesses to the robbery, but his journey to Belgium remains unexplained. Perrin, with the help of his old friend, Johann Berndt, formerly Vienna's chief of police, starts to trace what looks suspiciously like an international criminal network. An alluring Hungarian countess, an influential financier and a young Englishwoman become swept up in Perrin's remorseless hunt for the truth, which takes him across Europe before discovering the key to the mystery lies closer to home. Two will die, and Christopher Perrin will risk his life-and his heart. The End of the Chase was originally published in 1932. This new edition features an introduction by crime fiction historian Tony Medawar.
