Irish Detectives

I'm thinking about starting a detection novel (mystery or thriller) based in Ireland.

Are there any already out there (fictional detectives based in Ireland)?

Google has come up with:

Peter Tremayne - The Sister Fidelma series
True Believer by Tony Higgins
The Midnight Choir by Gene Kerrigan

Like Barack O'Bama?

I now have:

Ken Bruen (Jack Taylor series)
Benjamin Black
