JakeElwood, if you liked Lawrence Block (obviously!) you would also like Michael Connolly and to a lesser degree, Stuart Woods.
You're right about Michael Connelly, I've read 'The Poet', 'The Narrows', 'Blood Work' and 'Void Moon'.
I read 'Chiefs' by Stuart Woods a good 10 years ago, but I don't remember seeing much else by him in UK libraries or book stores. What do you think are his best books?
I also like reading George Pelecanos, James Sallis, Jeffery Deaver, Don Winslow, James Lee Burke, Robert Crais, Walter Mosley, James Ellroy, John Sandford, Tim Dorsey, Harlan Coben, Daniel Woodrell, Elmore Leonard, Edward Bunker, etc.
Plus old crime classics by Dashiell Hammett, Raymond Chandler, James M. Cain, Jim Thompson, Mickey Spillane and Patricia Highsmith.
