Including Coben and Crais, I've also read all the novels from Michael Connelly, Lee Child, John Sandford, and am currently reading Robert B. Parker's novels (although many of his older novels are quite hard to find around here).

If you're familiar with these authors, it's probably obvious that I enjoy reading the detective/crime fiction genre (especially from authors who feature a series around a specific protagonist [Bolitar, Cole, Bosch, Reacher, etc.]), so I'm wondering if people have suggestions of other authors similar to the ones stated above.

Oh, and I've also read the first few novels from Jeffery Deaver, Jonathan Kellerman and John Connolly, but their novels haven't really tickled my detective bone.
