Well I guess Sherlock Co. is only going to get a 1 star review on Yelp. 

...
Is there a Sherlock Co. on Yelp hold on guys I have to do some investigating. Wow Yelp is down $1 today, that's pretty interesting actually. 
Unfortunately the 'Co.' part of the search term floods me with nice bakerys and antique stores. (I haven't browsed their catalog yet.)
However, the first result is for [url=http://www.yelp.com/biz/sherlock-surveillance-san-jose-2?osq=sherlock+co.]Sherlock Surveillance[/url] which seems like they're taking the Sherlock bit at the opposite angle. 

And apparently the San Francisco police department only has a 2.5 average review score. Do you agree with that, David?
