There are far too many good crime and thriller writers out there to mention .
Have a look here
http://www.fantasticfiction.co.uk/
It gives you all the latest books an authors with a brief synopsis .
I have read all the Rankins and Reichs to date and they are a good read .Not keen on James Patterson though.
Reichs is far better than Patricia Cornwell whose last couple of books were awful .
If you like historical stuff with murder and mayhem thrown in try C.J. Sansoms Shardlake series ..brilliant .
On the other hand you can't beat good old Agatha Christie or Dorothy L Sayers .
Christopher Fowler is good and very underrated ...crime with a comic twist .I've read his Bryant and May series and they too are brilliant
Lee Childs ..Jack Reacher series is great ..there are loads of his fans on AB !
Peter Robinson has also written a good series .Inspector Banks .
Donna Leon has written a good series set In Venice the Guido Brunetti series
Hope you find something you like .
