It’s April, 1916. Dublin GAA footballer Frank Shouldice has just won the Croke Cup. It’s a big achievement, but he has other things on his mind. Two weeks after the final whistle he’s on a rooftop in North King Street with a rifle in his hand. His cheekbone is grazed by a bullet smashing into the wall behind him and, according to a confidential military file, Frank Shouldice is killed in action.

Except he is very much alive. His brother Jack commands the barricaded street below. In some of the heaviest fighting of the Easter Rising the South Staffordshire Regiment can’t budge a pocket of Irish Volunteers defiantly holding out. Through the sights of a borrowed pair of binoculars Frank takes aim from the Jameson malthouse high above. The street is soon littered with casualties and the British troops are forced to withdraw.

Pearse’s surrender begins the next chapter of this extraordinary story. In the eventful years that follow, Frank, formerly a civil servant, will spend jail terms in Stafford, Brixton and Wormwood Scrubs. When he gets home to Ballaghaderreen, County Roscommon he is placed under surveillance by MI5, the military and police in Ireland. He is court-martialled in Frongoch internment camp and incarcerated at Usk Prison in Wales, where he leads a daring four-man escape to freedom.

But he didn’t like to talk about it. And when Ireland’s War of Independence descends into Civil War he lays down his gun forever.
