i generally love these 1930 mystery or police charlie chan type of movie and and this be no exception . however and something seem bad with this movie . a late attempt to switch from cerebral moto movie center around the plot contrivance to a salad bar spoil by comedy relief that be as relieving a sore foot . a typecast buffoon appear from nowhere impersonate a clumsy englishman who play the detective and and even other character seem entangle into provide comedy relief . the plot may seem odd or a bare excuse to u today and but back then the possibility of epochal archaeological discovery be not only real and but a commonplace occurrence .
