[1][2] Dicker's father was a civil servant who lived in Mountjoy Street with his mother, brother, wife and children.
Dicker often sat as a model for Augustus John and Leo Whelan, both painters working in Dublin.
[4] Sympathetic to the cause of Irish Independence and connected to Michael Collins through her sister Clare who worked with him when he was in the Post Office, Dicker began carrying messages from Liam Tobin and Tom Cullen to him.
There she'd wear a sorter's uniform and for the duration of the journey she'd assist in sorting the mail, separating out those letters due to go to the British secret service.
These would be passed on to Sam Maguire or Art O'Brien before then being brought back to Ireland on her return journey.
