Wallace consistently denied having anything to do with the crime, but was charged with murder and stood trial at Liverpool Assizes. After conducting a secret mock-trial in London, which unanimously found Wallace not guilty, The Prudential Staff Union — in a unique act — sponsored his defence.[1] Despite the evidence against him being purely circumstantial, and the statement of a local milk delivery boy — who was certain he had spoken to Julia Wallace only minutes before her husband would have had to leave to catch his tram — Wallace was found guilty after an hour's deliberation by the Liverpool jury, and sentenced to death.
