In 1875, beautiful, vivacious widow Florence Ricardo married Charles Bravo, a dashing barrister. The marriage seemed to be a happy one, although society gossips whispered that Bravo had married Florence for her fortune. Behind his charming public persona, Bravo was a brutal, vindictive man who dismissed his wife's devoted companion Mrs. Cox and regularly subjected Florence to violent abuse. Four months after the wedding, Bravo collapsed and for fifty-five hours - with some of London's most distinguished physicians in attendance - suffered a slow and agonising death. All the doctors agreed - he had been poisoned. The police were called in and everyone in the Priory, the house in South London in which he and Florence had lived, was under suspicion. The investigation was detailed and sensational and such was the public interest that it even eclipsed the coverage of the Prime Minister's negotiations with Egypt and the Prince of Wales' tour of India. The suspects included Mrs. Cox; George Griffiths, a coachman with a grudge against Bravo and at Florence Bravo herself. This is the recreation of the case with new evidence to conclusively prove who did kill Charles Bravo.
