Nikita Hand won a civil judgment against Conor McGregor after the jury found he had committed sexual assault at the South County Hotel on December 9, 2018. Devon Marable does not treat it as a coda. He treats it as the fact the rest of the career now has to be read through. The career itself is short and enormous. Conor Anthony McGregor grew up in Crumlin, a working-class neighbourhood of southwest Dublin, apprenticed as a plumber under Brendan Egan, and signed on for unemployment benefits at twenty. He made his professional debut in mixed martial arts in 2008, trained at Straight Blast Gym Ireland under John Kavanagh, took the Cage Warriors featherweight title, and signed to the UFC in February 2013. He won the featherweight belt with a thirteen-second knockout of José Aldo at UFC 194 on December 12, 2015, and the lightweight belt with a second-round knockout of Eddie Alvarez at UFC 205 on November 12, 2016, becoming the first UFC fighter to hold titles in two weight classes at the same time. On August 26, 2017 he boxed Floyd Mayweather Jr., lost by tenth-round technical knockout, and earned an estimated $100 million. Marable follows the whole line: the Lourdes Celtic GAA years, the Aldo knockout, the featherweight-and-lightweight reign, the UFC 229 loss to Khabib Nurmagomedov in October 2018 and the brawl that followed it, the retirement-and-comeback cycles, the first-round knockout of Donald Cerrone in 2020, the leg-break against Dustin Poirier in 2021, the 2022 sale of Proper Twelve Whiskey to Proximo Spirits, and the political flirtation that included a lunch with Donald Trump in September 2024. What emerges is a portrait of a Crumlin plumbing apprentice whose ten years in the UFC remade what a combat-sports athlete could earn, and of a verdict his sport will spend the next decade absorbing. ## Contents 1.

The title never carries the subject's name: it names one concrete thing out of the life — in this case The Crumlin Plumber — and the name goes on the line underneath. **Is this an authorised biography?** No. No subject, estate, label or foundation had approval over the text, and none paid for a word of it. The cost of that independence is that no new interviews were conducted for the book; it is built from the public record, and it says on the page where a scene is reconstructed rather than documented. **Can I read some of it before buying?** Yes — the whole opening chapter and the writer's foreword, free and in full, with no email address and no account. That is 5,401 words of the book. **How long is it?** About 60,000 words, 19 chapters, 196 pages in the paperback. ## The writer Devon Marable spent a decade as a reporter for ESPN The Magazine before turning his attention to book-length biography. His writing focuses on the complex personal realities of athletes whose public careers dominated headlines while their private struggles and triumphs remained largely unrecorded by the daily press. Through meticulous archival research and deep interviewing, he reconstructs the quiet, human moments behind monumental sports histories. His published titles include The Chicago Compound, The Akron Origin, The Crumlin Plumber, and The Stolen Bicycle. He lives in Brooklyn, New York, where he spends his free time restoring vintage road bicycles and volunteering at a local youth community center.
