I was born in Dublin, Ireland in 1968 and have, at various points in his life, worked as a journalist, a barman, a local government official, a waiter and a "gofer" at Harrods department store in London. I studied English in Trinity College, Dublin and journalism at Dublin City University, subsequently spending five years working as a freelance journalist for The Irish Times newspaper, to which I continue to contribute, although not as often as I would like. I still try to interview a few authors every year, mainly writers whose work I like, although I've occasionally interviewed people for the paper simply because I thought they might be quirky or interesting. All of those interviews have been posted to my website, http://www.johnconnollybooks.com.

I was working as a journalist when I began work on my first novel. Like a lot of journalists, I think I entered the trade because I loved to write, and it was one of the few ways I thought I could be paid to do what I loved. But there is a difference between being a writer and a journalist, and I was certainly a poorer journalist than I am a writer (and I make no great claims for myself in either field.) I got quite frustrated with journalism, which probably gave me the impetus to start work on the novel. That book, Every Dead Thing, took about five years to write and was eventually published in 1999. It introduced the character of Charlie Parker, a former policeman hunting the killer of his wife and daughter. Dark Hollow, the second Parker novel, followed in 2000. The third Parker novel, The Killing Kind, was published in 2001, with The White Road following in 2002. In 2003, I published my fifth novel - and first stand-alone book - Bad Men. In 2004, Nocturnes, a collection of novellas and short stories, was added to the list, and 2005 marked the publication of the fifth Charlie Parker novel, The Black Angel. In 2006, The Book of Lost Things, my first non-mystery novel, was published.

Charlie Parker has since appeared in five additional novels: The Unquiet, The Reapers (where he plays a secondary role to his associates, Louis and Angel), The Lovers, The Whisperers, and The Burning Soul. The eleventh Charlie Parker novel, The Wrath of Angels, will be available in the UK in August 2012 and in the US in January 2013.

The Gates launched the Samuel Johnson series for younger readers in 2009, followed by Hell's Bells (UK)/The Infernals (US) in 2011. A third Samuel Johnson novel should be finished in 2013.

I am also the co-editor, with fellow author Declan Burke, of Books to Die For, an anthology of essays from the world's top crime writers in response to the question, "Which book should all lovers of crime fiction read before they die?" Books to Die For is available in the UK as of August 2012, and will be available in the US in October 2012.

I am based in Dublin but divide my time between my native city and the United States, where each of my novels has been set.
