The Linus Schag, NCIS Thrillers

Killers lurk beneath the waves of the western Pacific Ocean. The USS Encinitas, the first attack submarine crewed by both men and women, stalks the Crescent Moon, a renegade Iranian sub armed with nuclear-tipped missiles. But another predator hides aboard the American sub, a murderer who has already left a trail of dead women behind on shore. While the crew of the Encinitas plays a deadly game of hide-and-seek with the Crescent Moon, NCIS Agent Linus Schag must discover the killer's identity before his - or her - blood lust leads to the submarine's total destruction.

Meet William Butcher a.k.a. The Butcher, former Navy SEAL, now a disgraced ex-NCIS agent. Those who stole $9 billion in cash from Iraq want him dead. The cops want him for murder. Butcher's only hope is his former NCIS colleague and closest friend Linus Schag. Together, Schag and Butcher tear away the veil of conspiracy, uncovering a criminal enterprise reaching into the highest levels of government. 

NCIS Special Agent Linus Schag is no stranger to violence and bloodshed, but when he’s sent to Iraq to take custody of two Navy SEALs suspected of murder, he finds himself thrust into a manmade inferno as coalition forces fight to free Northern Iraq from the Islamic extremist group called ISIS.
