Anything I can think of to recommend, you can already borrow from me. Hmmm...

Fiction, non-fiction, genre, light vs heavy, series v standalone, etc?

"Thump, Quack, Moo". Definitely.

"Stories", the new short story anthology edited by Neil Gaiman is looking good. Out mid June.

If you want to try something really off the wall, there's The Third Policeman by Flann O'Brien - short, funny and as weird as it gets.

In that case, can I recomment his comic journalism under the Myles na gCopaleen name? The selection I have is just called The Best of Myles and is good stuff, although it's a cheapie photo-reproduction of an old edition so rather hard to read in places.

Alternatively, Carter Beats the Devil by Glen David Gold is a terrific book, lots of fun.

The Automatic Detective by A. Lee Martinez.

Checking your list of 100 bEst BEach Books for what you haven't read, I'd recommend "Life of Pi, by Yann Martel".

Yes, that's unfortunate. I found it very entertaining and engaging, and never got the mixed reactions many people had to it.

I know this is all very late but all I could think of was crime noir. Almost anything by Walter Mosley.

Or try 'Pimp: The Story of My Life' by the wonderfully named Iceberg Slim. Or 'Mr. Blue: Memoirs of a Renegade' by Edward Bunker. Both are 'autobiographies' which slightly glamorises the life of crime and qualifies them as crime fiction I think :p
