Rory Cowan has begun writing a new lockdown book - a crime novel based in 1970s Ireland.
The former Mrs Brown's Boys star got the writing bug last year when he wrote his best-selling autobiography.
During lockdown, he found himself stuck alone at home and decided the time was right to let his imagination run wild.
He admitted he was going mad on his own over the past 12 weeks, and in a bid to stop snacking he started writing.
Before long, he came up with an Irish thriller, which he hopes can become his second publishing hit.
"I've put on a bit of weight because I've been snacking," he said. "Every time I put on the kettle, there has to be a snack or a biscuit. I'm dreadful. I'm eating biscuits and cakes and I'm diabetic.
"I'd go out for a walk for something to do, because being stuck in the house I would have gone mad.
"So I went to the supermarket every day and then I started to write another book. I haven't finished it, but I'm working on it now."
Rory's fictional story surrounds a mysterious death in 1970s Ireland, which becomes a dark secret for one family.
"It's not a dark book, but it is about solving a crime that you didn't know was a crime and all the evidence comes from dreams," he said.
"It goes back to a time I love, so the crime happens in the Seventies and the only evidence of the death comes from these dreams in the present day, which are all true events.
"It's set in a small town and has one main dysfunctional family who have been torn apart by this event.
"I have loads of ideas. I'm 60 years of age, and if I can get this one published, I would be over the moon.
"At least it stopped me snacking."
Aside from writing, Rory is hopeful he will be going back to work in Fair City over the coming weeks.
He said that only for RTE's health and safety practices, he would probably not be returning to Carrigstown.
"It's in RTE, and when they decide they're going to restart filming, I would be confident it will be safe to go back to work," he said.
"That's fine, and I don't mind waiting. I'm lucky that I'm in that position workwise and I don't have to take chances.
"Another broadcaster could be cutting corners when it came to social distancing with crew, but RTE won't be.
"I'm very happy with that. So, when they say it's time to go back, we can all go to work if we're being looked after properly.
"A lot of people may think RTE wastes a lot of money, but not on things like health and safety, so if I was working for other TV stations, you'd never know.
"With RTE, they'll be so strict on health and safety."
