Catherine Suttor attended the Bathurst 'Ladies College'. She married her cousin, Allan Suttor of 'Wallerwaugh', the sheep station where the hundred-weight of gold was discovered in the 1850s by an Indigenous employee.
During a particularly dire season for stock owners, Suttor decided to take up writing to earn additional revenue. She sent in a story to the Mudgee Western Post, one of the oldest country papers in New South Wales at that time. Her story, entitled 'The Whisper of Satan' was published in the Post's Christmas issue for 1896, under the pseudonym of 'Harold King'. Acting on the advice of several editors, Suttor abandoned the pen name.
Catherine Suttor also wrote for several other leading country papers, including the Coonamble Times, Grafton Mercury, Wellington Gazette, Hay Standard, Grafton Times and the Orange Advocate. Having gained some success with these papers, she then tried some of the Sydney and Melbourne papers, receiving acceptances from the Austral Light, Co-operator, Sydney Mail, Australian Journal, and Cosmos Magazine.
