Cabot Cain is a freelance operative who works almost exclusively for Interpol, Department B7, handling tasks that most others would avoid. These assignments are usually presented to him by his close friend, Colonel Fenrek. It is Fenrek that Cain uses to provide needed background information to discern the good guys from the bad. It is Fenrek that sometimes has to prod Cain into taking an assignment if it doesn't sound interesting enough at the outset. Cabot Cain is a big man. A really big man. He stands 6'7" and weighs in the neighborhood of 230 lbs. He remains in excellent physical shape due to an almost fanatical exercise regimen. And he has the brains to go with the muscle. Holding numerous degrees he prefers to use his mental attributes and physical strength instead of guns to get himself out of the tightest situations. And with each case, those tight situations end up being near brushes with death. The order comes down from Interpol and soon Cabot Cain joins his friend Colonel Fenrek in the frantic search for Major Loveless, a ruthless mercenary soldier notorious for his disregard of human life. Without any clues and with only a vague description of this callous killer, Cain is off on a trail that takes him from the streets of Lisbon to the very depths of the ocean floor, where he will come face to face with his enemy in deadly underwater combat. For getting Loveless is imperative before he has a chance to unleash a deadly nerve agent upon an unsuspecting city if ransoms are not paid.
