Dumb Witness = Безмолвный свидетель

A book for reading in English.
In the house of a blind teacher, a secretary sent from the bureau finds a corpse. A passing employee of the Foreign Intelligence Service, on his official business, becomes embroiled in the investigation of this... murder. For some reason, there are many more clocks at the crime scene than there were before. What are the extra hours for? Who was killed and why? And most importantly, who? What does the secretary have to do with it? How did an unknown corpse end up in the house? Scotland Yard cannot find answers to these questions, the intelligence service is powerless, and the bored Hercule Poirot, who is reading classic detective stories in his spare time, hardly leaving the house, finds the murderers, traces the fate of a large inheritance, uncovers a spy network, and ties all the loose ends together. The simple language, tightly woven plot, elegant resolution, glossary, and comments will provide detective enthusiasts with unadapted English a few pleasant hours in the company of the most famous Belgian.
