This time, we have Poirot trying to decipher the murder of a Chinese man in China Town. It's a story of betrayal, money, business, Opium and gambling. The Red Dragon Club is very exotic and ticks all the right stereotype boxes. You can see it's one of the older episodes, but it retains everything that's usual quality of the series, so it's amusing and enjoyable, especially with his indispensible team of Hastings, Japp and Miss Lemon.
