A Chinese man arrives at a London hotel; he has with him the map to a long-considered "lost" mine, and he has agreed to sell the map to an English bank. But the next day he doesn't turn up at the time of the meeting; in fact, after a few hours, he turns up dead. The president of the bank asks Hercule Poirot for help.
Apart from the Oriental flavor (it's partly shot in London's Chinatown), and a brief look at Scotland Yard's methods in the 1930's, this is for the most part a rather trivial episode of the Poirot series. But it is saved at the end by the startling revelation of the killer's identity. Up until then, it's a ** out of 4, but the last 5 minutes make it a ***. One of the clues is so obvious in retrospect that you may feel like hitting your head on the wall if you miss it (and I did....miss it , I mean).
