Upstairs, Downstairs

Word of Honour (3x7)

:

Acting on a tip from a friend, Richard quadruples his stock market investment in a matter of weeks. When it turns out that the company he invested in just landed a government contract, he's accused of insider trading. Richard denies learning about it in Parliament, but refuses to divulge the name of his friend, and when Hazel and Hudson go behind his back to determine his friend's identity, Richard is furious.
