During her criminal career, she had amassed 100 convictions in New South Wales, Victoria, Queensland and Western Australia for prostitution, vagrancy, consorting, assaulting police and the public, keeping a brothel, drunkenness, and drunk driving, and was sent to prison on numerous occasions.

[4] Markham had been described variously as 'beautiful platinum blonde', 'innocent face and baby-blue eyes', and 'ravishing figure',[5] and 'tall, curvaceous, slim-ankled, creamy complexioned... glamor girl of the demi-monde, attractive even to a husky voice'.

[6] The Daily Mirror, a former Sydney newspaper, summed up her career in crime thus: "Dulcie Markham saw more violence and death than any other woman in Australia's history".

When picked up for vagrancy by local police,[5] 'Pretty Dulcie' protested that she lived with her current de facto husband, taxi-driver (J)ames Arthur Williams, and that while he gave her money and groceries, she was not involved in the local sex industry at that time, and was not aware of Williams' involvement in the sly-grog or bootleg alcohol distribution networks that flouted wartime beer and spirits rationing mandates.

[23] Markham and Edwin Martin, her current liaison, had visited a boarding house owned by Mrs Hull and had demanded to see her.

[24][4] On 25 September 1951, Markham was shot in the hip at a wild party that turned violent in St Kilda, Victoria.

After this period, little more is known about Markham's subsequent life, until her death in a house fire at her home at 12 Moore Street, Bondi on 20 April 1976.

Markham's funeral was held at St Patrick's Catholic Church, Bondi and the eulogy was given by Detective Frank "Bumper" Farrell.
