Detective First Grade

Description for DETECTIVE FIRST GRADE by Dan Mahoney:

There's a secret war on the streets of the city. Only a New York cop can win it.

His claim to fame is finding guns on the bad guys, and Detective Second Grade Brian McKenna has just spotted the beard carrying a piece. What he doesn't know is that he's about to shoot his way into a war with a highly disciplined, well-armed enemy so treacherous, not even the NYPD knows they exist.

Exiled from the bright lights of Manhattan for breaking one too many rules, pressured by his girlfriend to quit the job, this is McKenna's last chance to win back his reputation and make the coveted rank of Detective First Grade. But if his moves aren't swift and right, a new breed of criminal-- who has found a leader in an exotically beautiful and ruthless woman-- will own his city.

From the savvy and experience of a cop who gave over 25 years of his life to the NYPD comes a stunning novel of undeniable authenticity and unrelenting suspense.

This is #1 in Brian McKenna and Cisco Sanchez Mystery.
