'Dirty Harry' Callahan is back. The Magnum maverick from Homicide. Who blows away the rules when the rules get in his way. And blows away the opposition like a .44 force in his own heavy calibre campaign of war on the most wanted.
__Dirty Harry's back, blasting his way from the mean streets of San Francisco to the blazing byways of San Antonio. His target—a crime boss who's got the whole town under his thumb, cops included.
__Harry's all alone now with nothing except his hand-held enforcer, a stash of dirty tricks up his sleeve and a deeply held belief that the best way to a man's heart is clean through the ribcage.

Dirty Harry's back and it's a labor of love when he busts a Labor racketeer. Especially when the Union boss is Matt Braxton, the biggest deal on the docks. Corrupt enough to be cosy with the Mob, rich enough to afford the price of friends in high places, ruthless enough to wipe out anyone who stands in his way.
__And starnding in his way right now is Dirty Harry. Who negotiates from strength and knows that any enemy will see the point when he's hit smack between the eyes.

There's trouble on campus. But these days the students at Berkeley, across the Bay from San Francisco, aren't protesting, rioting or dropping out. Instead they're being taken out. Vanishing. Not seeking the hippie dream but driven into white slavery. Drugged, beaten, tortured, Californian beauties turned into brutalised sex slaves. Killed if they resist.
__Dirty Harry's no academic. But he does know how to drive home a lesson and set up a final examination. With a bullet.

Dirty Harry's all at sea: an ocean fishing trip on a millionaire's yacht down Mexico way. But the Big Game he hopes to net are heroin smuggling pirates and Harry's boat is the bait. Unlike their victims, they're hard to get hooked and harder still to land.
__Still, when Harry starts to shoot up he scores a lot of hits and terminates a lot of lifetime habits as the blue Pacific waters are bloodied red by a Force Ten storm of lead.

And this time he's on the East coast—for the first time in ten years. Visiting relations in Boston. But this is no quiet domestic reunion—not with a knife-wielding rapist cutting a swathe of bloody terror through the rain-sodden streets. Not with Dirty Harry dragged into the hunt and dispensing his own particular brand of instant justice.
NEL 0450-05650-3, Jan 1984, 192pp, £1.50.
Winos brutally slaughtered on San Francisco's skid row. Beautiful young women butchered in the act of sex by a perverted killer. Or killers? For this psychopathic rampage seems almost too much for one man to carry out. But one thing is sure, one man is going to find out. Dirty Harry. Who will chase and wade through the sexual sewers of the city's underworld, struggling through the depraved flotsam that drifts with night-time currents. For this is a manhunt that will leave only one survivor.The series was continued by Warner Books for a further six titles which were not reprinted in the UK.
