Zeropoulos

In the novel Death in the Clouds, Zeropoulos is a Greek antique dealer who owns a shop on the Rue St Honoré in Paris. He is described as a "short, stout little man with beady black eyes". He talks "volubly and at great length".

Zeropoulos says that he sells a little of everything, although his speciality is items from Persia. He buys articles from sailors, usually at a low price. He has no fixed price for the items, and if a customer expresses interest in a particular item, he makes an estimate and asks a price.

Zeropoulos tells M. Fournier and Poirot that he sold a blowpipe and darts to an American man. After he read about the murder of Madame Giselle in the papers, he wondered if the blowpipe used was the one he had sold, and communicated with the police.

Zeropoulos describes the blowpipe and darts that he sold, including the fact that the darts a had fluff of red silk on them. This differs from the dart found in the Prometheus, which had a fluff of yellow and black silk.
