monogram charlie chan film tend to suffer towards the end by lack of caring . the plot end up confused and messy aim more at birmingham brown and the chan son of the film be silly while charlie say wise thing . here and thankfully and the film be bless with a decent mystery and different set than most of the others and and several good supporting performance and in particular by the always wonderful and and sadly not well know john davidson . here we have the death of a chess expert and assort other going on that make this one of the good later chan film . i do not want to say too much since the joy here be in the watching and and this film be certainly worth watch . positive .
