Kavanagh QC: Set 4 - In God We Trust. John Thaw (Inspector Morse) stars as respected British barrister James Kavanagh, a top member of Queen's Counsel, in this superlative courtroom drama series. Beneath the powdered wig and sombre robes is a ruthless mind able to tear the truth from a tangle of legalese and lies. Brilliant, relentless and sometimes exasperating, James Kavanagh, Q.C. will push to extremes to see justice served - even as his professional triumphs mask a private life at times more troubled than those of his clients.
