The secret of three quarters

"Rare talent to be incredibly unpredictable - this is what unites Sophie and Agatha Christie. Both are able to show how the impossible becomes possible.
- Sunday Telegraph
"Hannah and Christie is a truly union imprisoned in heaven."
- The Times
The most beloved detective of the world, Erkul Poirot, returns to the stylish, devilishly twisted detective Sophie Hannah - the pride of modern British prose.
Returning after the pleasant lunch, Poirot collided at his doors with an extremely angry woman. She received a letter from him with an accusation of the murder of an unknown man named Barnabas Pandi. This name is completely unfamiliar and the detective himself, who, of course, did not write anything like that. But it was strongly impossible to explain this angry fury. After she left for the house, another displeased visitor burst, who received the exact same indictment. And the next day, another showed up ... How many letters did the false Poirot sent? And who is this mysterious Monsieur Pandy, of whose death an impostor accuses people to the right and left?
