skullduggery

Due to lack of transport, v ar and old-fashioned skullduggery, Manchuria's whole export trade was in bad shape.

战争，运输工具短缺，尔虞我弊，一洲整个出口贸易陷入绝境。

His defense, which seems credible on the evidence so far, is that the bank masked its skullduggery so completely that no regulator anywhere in the world could get a handle on it.

他辩词(根据目前证据似乎可信)是：银行把它偷天换日做法遮掩得天衣无逢，全世界任何地方监管人员都无法掌握。
