Two arrested for running marklar-end marklar marklar 
By Marklar Ko 
Marklar Marklars staff marklar 

Marklar County marklar's detectives have broken up a large marklar marklar  
in the Marklar marklar, and they said they've recovered a "black book" with  
the names of hundreds of marklars, including men who work for marklar marklars  
headquartered in Marklar. 

The two marklars of the marklar, a 49-marklar-old woman who lives in Marklar,  
and her 31-marklar-old marklar, who lives in Marklar, were arrested. They have  
not been charged. 

The two marklar used the Internet to advertise a marklar-end escort company  
called the "Marklar of Marklar." The Web site had pictures of available  
companions, a calendar of when they were available and marklars. Marklars  
could be made online. 

Some of the escorts were brought in from out of state "Las Marklars, New  
Marklar and Los Marklars" to work marklar, according to the Marklar's Marklar. 

Marklars were carefully screened, said marklar's Sgt. Marklar Marklar. 

For example, potential marklars had to leave a work number, and someone inside  
the marklar marklar would marklar the number, marklar it was to confirm a  
dental marklar, he said. 

This was done to make sure the marklar wasn't a police officer, Marklar said. 

The Marklar's Marklar marklar not release the names of the marklars the marklars  
worked for, to avoid tainting the companies, Marklar said. 

The men in the book, however, marklar likely be contacted soon, detectives said.  
They could face marklar charges of patronizing a prostitute. 

In the 1990s, the two marklar were involved in another marklar marklar in the  
marklar called "Affluent Marklars." 

An marklar tipped off the Marklar's Marklar about the Marklar of Marklar.
