It says number 1 on the cover, but there was never a number too. This Lou Cameron novel taunted me for a year before I found a copy that was cheap-enough to justify a "one and done" series. I like Cameron's stuff, in fact one of the first things that ever saw print with my name on it was a review of a "Renegade" adult western in Justin Marriott's fantastic fan-zine "Hot Lead." Lou Cameron was a prolific writer with a lot of books under his belt, westerns, crime, ti-ins, even comics. For books like this he's got a nice professional blue-collar--room style that's pretty fun-loving at times. It's very much a modern (at the time) take on Dick Walker aka Captain Gringo in the Renegade series, it gives you the same thrills, sex and the tongue-in-the-cheek appeal.
The titular "Blaster" is Boomer Green. You can tell he's a demolition expert since both of his nicknames describe explosions. Actually he's never called Blaster, I wonder if Cameron wanted the series to be called "Boomer." They did this multiple nickname bit a lot in 70's Men's adventure books. Boomer is a colorful lead character, sarcastic, eager to bed the ladies, packs a .25 caliber Baby Browning in his shirt pocket, and blow shit up. He's down in Brazil to break up a massive log-jam for a drug-addicted Ex-Nazi, his maybe-Nazi daughter and his drunk son. Boomer finds himself at the estate of the said Nazi's when it becomes clear that all is not right. Forces conspire against him, questions are raised about motives, people try and kill him. But that's all in a days work for Boomer so he takes it in stride. Cameron builds the tension well, Boomer literally planting the bombs as the book builds to explosive climax.
Cameron's an old pro and this is a "good-time" book. It's got a pleasant south-of-the-border adventure vibe with great jungle scenes, a bit of a "plantation novel" vibe with the household and the servants, and the action is handled expertly. The mystery of the forces against Boomer are built up nicely and dispatched nicely. Sorry for the spoiler, but like is the main character going to die in a book with a #1 behind the title? Cameron was a step above a lot paperback writers of the era and it's a shame there wasn't anymore Blasters, I'd read 'em.
