Try the Chris Ewan series: The Good Thief's Guide to Amsterdam [1]. There is also Paris and Las Vegas, although I am not sure of their numerical order. There might be other titles, but those are the 3 that I have. I have read the 1st, and it is quite good.

This is an older series, by Lawrence Block. There are at least 10 titles; the first one is: Burglars Can't Be Choosers. I haven't read any of them, so I can't really comment on the writing.

Try Prince of Thieves by Chuck Hogan. The movie "The Town" directed by and starring Ben Affleck was based on this novel.

Arthur Conan Doyles brother-in-law E.W. Hornung wrote a series of novels and stories about a safe breaking gentleman thief, Raffles. There is also a laundry list of books penned by Marcel Allain following the exploits of the evil genius Fantômas.

On the fantasy thread there is also redemption of althulus by david eddings, although his other series also include a thief as part of his band of merry men!

Try Among Thieves by Douglas Hulick. It's Locke Lamora a la Brent Weeks.
