In mid 1919 Theodor Flynn moved his expecting wife and 10 year old Errol from Holebrook Place to the Imperial Hotel located on Collins Street.
As quoted by Bob Casey, a nurse named Elsie Hinds felt sorry for Errol when he was left alone. She often took him to the wharves to see the ships in port, flying the flags of all nations of the world.
Don Norman wrote, “Elsie remembered Errol standing politely and removing his cap when she stopped to speak with one of her friends.” A maid at the hotel remembered giving Errol money so he could go to the cinema.
It is stated in several publications that Errol had no spending money, was a neglected child but had very good manners. One could take a good guess and see that his pranks most likely have been fueled by being a neglected and abused child and therefore became his way of retaliation.
