Speaking to the Irish Independent six months after Ms Shanley’s death, Caitríona said: “She was sick before she took on the Six One, but the only people who knew were me and our boss. So she and I were carrying that secret, and you have to have massive respect for someone who does what we do.
“For Keelin, journalism was a vocation and part of who she was. She wanted to work on, and write her book because she didn't want to just be this sick person.
“Everyone deals with these things in their own way. The work was important to her. We are a family in RTÉ and people give out, and they're entitled to their opinions, but we have each other's backs.
"You work incredibly long hours and you're in very difficult situations, so you form really close bonds with people, whatever their job title is.”
