The Mystery of Edwin Drood

One of the most mysterious works of world literature, which is included in the cult American list “100 best detective novels of all time”.
The last novel of Dickens, and the remaining, alas, unfinished. And for almost a century and a half, literary critics and just lovers, researchers of the work of the great English writer, his modern brothers in Peru, and even police detectives are fighting over the question: what should be the end of this novel?
So who killed the rich heir Edwin Drud? Uncle-Haro-Jasper-a regular of the opium chicken coil of the gloomy old woman? Or the main suspect police - Landles who had grown up on Ceylon, who was insanely in love with Edwin Rosa"s bride?
Anyway, was the DRUD, whose bodies were never found, really killed?
