June 1849: Dr William Wilde, passing a wretched hovel in Dublins Liberties, discovers James Clarence Mangan in a state of indescribable misery and squalor. Aged just 46, the man dubbed Irelands National Poet is about to succumb to the cholera epidemic that is gripping famine ravaged Ireland.

August 2008: Writer Bridget Hourican encounters Mangan during a Liberties lock-in with that other great Irish poet, Shane MacGowan, who found inspiration in Mangans poetry.

Alcoholic, opium addict, Romantic, Famine poet, Dublin street character and hero of James Joyce, the mercurial Mangan begins to obsess Bridget. The surviving biographical material - scant, subjective, sometimes falsified - both fascinates and frustrates her and she determines to find him. Who was this Baudelaire of The Liberties this lurker in Irish history whose enigmatic presence helped determine its course?

As the lines between research and real life become blurred, Bridget starts to notice aspects of her life bleeding into Mangans. An obsession becomes a haunting and she realises that the only way to truly reach Mangan is to reckon with her own ghosts.

Finding Mangan resurrects Irelands most enigmatic literary figuring, restoring his rightful place in the national consciousness.

Imaginative and absorbing, at last Mangan has found the perfect biographer. John Banville

I adored the writing. Its fizzing energy. Its spinning clarity. Its openhearted rigour.Alan McMonagle
