Detective Brian McKenna

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.

NYPD Detective Brian McKenna is back where he belongs-hunting down a mysterious killer who preys upon the city's most forgotten members. At first blush, it seems as if these homeless men have frozen to death on the city streets. But this succession of deaths seems too suspicious for McKenna to ignore. McKenna makes some curious findings: all the victims were HIV-positive, and all were seen taking their last drink from a bottle of wine given them by a gaunt, black-clad man who goes by the name "Hyde." Who is this sinister figure-and why is he killing harmless men who are already at death's door? A hell-bent McKenna must chase the murderer from the streets of Manhattan through Europe and finally to Costa Rica to uncover the astounding answer. With first-hand experience and masterful storytelling skills, former NYPD Capitan Dan Mahoney presents his most thrilling work to date.

A girl missing in New York. A political bombing in Iceland. No ordinary cop would see a connection. But Detective First Grade Brian McKenna didn't earn his reputation by being ordinary. In Once In, Never Out, McKenna travels the globe in pursuit of his darkest foe yet-a terrorist bomber whose next target could be New York's St. Patrick's Day Parade. Along the way he finds a good friend and cunning ally in Thor Erikson, Iceland's sole homicide detective. This is a case that brings McKenna to the edge of his abilities, and puts both his detecting and survival skills to the ultimate test.

In a secluded New York City park, a double homicide draws two detectives named McKenna. One is a legend; the other is a brilliant young investigator. Together, they are entering a case that will grow more bizarre and more horrifying with each new piece of shocking evidence... One of the victims was tied to a tree and slowly tortured to death. Veteran detective Tommy McKenna realizes that he has seen this killer's work before- eighteen years earlier... Tommy will get a second crack at his killer. Brian McKenna gets to work with a legend. And, both men are setting in motion an investigation that will take them to California, Arizona, a Costa Rican mountaintop, and all the way to the Fare East. The two McKennas are on the trail of two human monsters who have been killing for two decades-and murder isn't even the worst of their crimes...

In the mountainous north of Spain, on a quiet Sunday morning, a Basque terrorist group kidnaps the country's wealthiest woman after a violent ambush along a winding country road. At the same time, in New York City, a murderous shootout alongside Central Park leaves two dead and Spain's ambassador to the United Nations held hostage. NYPD Detective First Grade Brian McKenna and his partner Cisco Sanchez (the self-described world's greatest detective) are assigned to the Joint Terrorist Task Force. The task force is focused on locating the ambassador, but for McKenna, the investigation becomes urgent when he learns that the kidnapped woman is Carmen de la Cruz, a personal friend. The search begins for two dangerous cells, one in New York, the other in Spain. McKenna and Sanchez work with the FBI, ATF, and state troopers to comb the city and eventually the state, but in Spain the investigation is stalled-until the two detectives negotiate an unprecedented role in a foreign police matter. When they arrive in Madrid, McKenna and Sanchez are caught in the crossfire of a war between Basque nationalists and the Spanish police themselves. Intercepted cellphone calls lead the partners to resort area of Gibraltar, and a complex of caves beneath the famous rock that might conceal Carmen and her kidnappers. Combining terrific suspense, only-in-New York characters, and firsthand knowledge about how an international terrorist incident is investigated, The Protectors is Dan Mahoney at his best.
