One of the guys that works for me is a huge fan of SH (and I loved his books as a youth.) I don’t read detective novels much any more, but would like to find a series that have the same “feel” as SH did to pass along to him. Are there any such?
There is a positive mania today for writing pastiches of Sherlock Holmes. A pastiche is a novel in the style of, using Holmes himself or one of the subsidiary characters. Some star Mycroft Holmes or Irene Adler, for example. Most of these are serious in intent, although some are comical. Parodies are a different animal, mocking Holmes or Holmesiana in some way.
Hundreds of these novels now exist. I loathe them myself (though I’m a parody fiend), so I can’t point you to any. But I have found some lists.

These just scratch the surface. Any Borders or B&N probably has a whole section of “new” Holmes books.
There was a PBS series in the late 70s called The Rivals of Sherlock Holmes about all the also-ran contemporaries cashing in on the Holmes craze in the 1890s. I don’t remember a one of them, though.
Maybe Fantomas or Spring-Heeled Jack for villains of the same era?
I misread the OP and thought he meant contemporaries of Sherlock Holmes. Still, here’s a quote from the IMDB about The Rivals of Herlock Holmes for those interested:
Try any of the Lincoln Rhyme series of books by Jeffery Deaver. *The Coffin Dancer * and *The Bone Collector * are very good. They are about a brilliant forensic detective who is crippled in an accident on the job and analyzes cases from his apartment. Its well written detective fiction.

Check out who’s on the cover of Sherlock magazine. I was going to say Gil Grissholm of CBS’s CSI…but this affirms it. 
My two all-time favorite detectives are Sherlock Holmes and Nero Wolfe. Both series have similarities: a super humanly smart but eccentric detective, an assistant who narrates the stories but doesn’t really know what’s going on, a bumbling police chief/foil. The Nero Wolfe stories are set in contemporary New York (they begin in the 1930’s and end in the 1970’s although the characters don’t age that much) and are really entertaining. Archie Goodwin, Nero Wolfe’s assisant, is a bit more of a smart-ass than Watson tho’. The Nero Wolfe series is written by Rex Stout.
If we’re allowed to mention TV shows, I’ll say Det. Goren from Law and Order: Criminal Intent. The guys knows everything there is to know and doesn’t miss the tiniest clue. He has that Sherlock Holmes arrogance as well.
In the wake of the PBS series The Rivals of Sherlock Holmes they published three paperbacks containing the original stories. They were:
The Rivals of Sherlock Holmes
More Rivals of Sherlock Holmes
Cosmopolitan Crimes: The Foreign Rivals of Sherlock Holmes
You might be able to dig these up on-line, at a used crime bookshop, or at a mystery con.
Of the Sherlock Holmes imitators, I have to give my vote to the stories collected as The Exploits of Sherlock Holmes, written by Adrian Conan Doyle (Sir Arthur’ son) and John Dickson Carr. More tha any other imitation, I feel these best capture the “feel” of Doyle’s originals. (Others disagree, I know)
You might also look up other Doyle collections, if you really want the feel of the original – Doyle wrote other mysteries besides the Holmes stories, and they have been variously anthologized. In fact, some mention an un-named detective (who might be Holmes. Or, some suggest, Watson), and these stories have beenb called “the Apocrypha”.
There are some Japanese manga and anime homages to Sherlock Holmes as well. A manga series called The Kindaichi Case Files is aimed at a younger audience (I guess closer to Encyclopedia Brown than Sherlock Holmes) and is really pretty entertaining.
In anime, there’s a long-running series called Detective Conan, named after Arthur Conan Doyle. It’s currently running on the Cartoon Network as “Case Closed.” Again, it’s aimed at a younger audience.
Probably not what you’re looking for, but they’re entertaining.
The List of 7 is an entertaining Holmes pastiche. Not what the OP was asking for, though; the thread seems to have veered off-course a bit.
The thing that made Sherlock so great in his day, was the fact that he knew almost every person in England. You could name somebody and not only would he tell you about the person’s occupation but also give you a brief geneology of his family. If he didn’t know the name, surely he had it in his “files”.
That kind of personal information is not something one could use in todays scenarios. My vote for the closest has to be Grissom as well.
I read the List of 7 and its sequel The Six Messiahs. They weren’t bad, but not up to the original, IMO.
Just to elaborate, the protagonist of The List of 7 and The 6 Messiahs (by Mark Frost, co-creator of the Twin Peaks television show) is Arthur Conan Doyle (playing on the myth that the Holmes stories were semi-autobiographical). I loved those books (and am disappointed that Frost has yet to continue the series) but I wouldn’t consider them very Holmes-like.
I also recommend the Sherlockian.Net website (which Exapno Mapcase has already mentioned) as a good place to look for other works of mystery.
Anyhoo…
The movie version of The Name of the Rose was very deliberately Holmesian. I can only assume the original book by Umberto Eco was similar.
Johnatan Creek seems to be sort of cunningly clever in that way too.
I too would suggest Nero Wolf as the closest contemporary fictional detective to Holmes.
I’m with Lisa. I beleive that Det. Goran on Law and Order: Criminal Intent is modeled on Holmes. He’s amazingly smart, has devoted his intelligence in its totality to learning how to fight crime, is eccentric and at least a bit arrogant, and tends to solve crimes in progress rather than puzzling them out after the fact. The one person able to defeat him was an attractive young woman who he underestimated because she was attractive and female. All nice parallels to Holmes.
Of course there is Baring-Gould’s theory that Wolfe was Holmes’s son…
Indeed, even the creators of the show describe Goren as a modern-day Sherlock Holmes.
(No cite – you’ll just have to trust me when I say I read this in an old issue of TV Guide.)
Yes it was, and much better than the movie too.
