George Dean had already escaped the gallows once, pardoned after a Royal Commission cast doubt on the poisoning case against his wife, Mary. Then a North Shore chemist named Smith came forward, admitting he had sold Dean arsenic and strychnine after Dean claimed he needed a double dose and two poisons to deal with rats on his property.
On 5 October 1895 detectives approached Dean just as he stepped off his ferry at Sydney's Circular Quay, still dressed in his captain's uniform, and arrested him again. "I wonder how many more times I shall be arrested over this affair," he remarked, before going with the detectives.
Dean subsequently confessed in writing to poisoning his wife. He was convicted of perjury committed to procure his own acquittal and sentenced to fourteen years, while his former lawyer and others faced charges of conspiring to pervert the course of justice.
