Chapter 1:

Six and a half years ago

CSM Kolt Blye was perched on an adjacent rooftop to the dilapidated abandoned warehouse their target MAJ Mike Brody was in. And thanks to the wires that the two UC's were wearing he could hear everything. The task force leader NCIS Assistant Director Owen Granger said we'll give them a little longer. "

Kolt replied tersely as he kept his eye glued to the illuminated reticle of his Nightforce PRECISION BENCHREST 12-42×56, ""We can't move in until we get the signal; Owen."

Granger gritted his teeth as he tried to keep his temper in check. He hated working with the Delta Force sniper. The man was a brusque acerbic, sarcastic and mercurial person and often very infuriating but Granger had to admit Kolt was also one hell of an operator. Kolt stated as he pulled the stock of his 7.62×51mm Lapua Desert Tech Stealth Recon Scout tighter into his shoulder, "If my sister is hurt in any way because of your incompetence then me and you are going to have words."

Granger glared down at the Delta sniper as he stated in a haughty voice, "Watch your tone CSM Blye; remember I outrank you."

Kolt was about to say something when he heard the prearranged signal. He instantly snapped into sniper mode; as Kensi called it and heard Granger give the go order. As soon as the SWAT team made entry he heard gunfire. He was scanning the roofline and other windows when he spotted two tangos run out of the warehouse brandishing 9 mm HK UMPs. He put the illuminated reticle on one of the tangos chest and gently squeezed the trigger and watched as the 175 gr moly-coated boat tailed lapua atomized the hostiles heart, then he transitioned to the other hostile blew his head apart like overripe melon. Granger said, "Good shooting."

Kolt grunted as he rapidly worked the bolt and shot a hostile that had just climbed out on the roof and was looking for targets when he caught movement in his periphery. His blood froze for an instant as he watched a hostile drag a clearly wounded Kensi out of the warehouse and press a .50 AE Magnum Research Desert Eagle to her head.

The instant the hostile put the Desert Eagle to Kensi's head Callen Sam and Deeks all took up defensive positions as did the SWAT team. The hostile yelled, "Lower your guns or I'll blow this bitch away."

Callen said as he and the others lowered their 9mm SIG SAUER P229 DAKs to the ground, "Alright just calm down you don't want to do this."

The hostile bellowed, "Kick 'em away."

They did as instructed as Sam said, "You know you're never going to get out of this alive if you don't release her and give yourself up."

The hostile cuffed Kensi on the side of the head with a resounding blow as he bellowed, "Fuck you man. This bitch and me are gonna have lots of fun. I'm go-"

He never finished his sentence due to the 175 gr moly-coated boat tailed lapua blowing his head apart.

Kolt was packing up his equipment when Granger rounded on him and bellowed, "YOU DID NOT HAVE PERMISSION TO FIRE. YOU COULD HAVE KILLED AGENT BLYE WITH THAT STUPID STUNT."

Kolt ignored Granger and continued with what he was doing. When he was finished he stated in a low menacing growl, "Don't ever raise your voice or speak to me like that again. I knew exactly what I was doing. Now I suggest we go see how badly my baby sister's hurt."

Then his voice took on an icier demeanor, "Don't you agree."

Granger simply nodded. He knew that Kolt was a fraction of an inch from hurting him severely and though he wasn't scared of the mercurial Delta sniper he knew that he couldn't take him in a fight. Kolt nodded as he, "Let's go."

15 minutes later they were all standing in the waiting room of Memorial Park hospital waiting for news on Kensi. Two of the hostiles attacked Kensi while Callen, Sam and Deekks were handling the rest of the gang. She had a broken and dislocated right shoulder, separated and broken ribs on both side, bruised and lacerated liver, lungs and kidneys, a fractured orbital socket, broken, jaw, nose and collarbone, a deeply lacerated and fractured cheekbone and badly swollen and lacerated left eye. Deeks walked up to Kolt and said, "Man; I'm real sorry. Kensi's my partner I should've had her back."

Kolt gave the LAPD Detective a look as he said, "It ain't your fault kid the blame lies with that no account piece of shit empty suit Granger."

Deeks nodded as Callen and Sam joined them. Sam commented, "That was some fine shooting CSM."

Kolt thanked him as he remembered operating with Sam Hanna when he was SCPO Hanna of DEVGRU. Just then Granger came striding in with Hetty by his side. He didn't know what made him do it but he stalked forward and flattened Granger with a wicked right hook. Granger looked up from the floor as Callen, Sam and Deeks tried to restrain the Deltas sniper, "WHO IN THE HELL DO YOU THINK YOU ARE? YOU JUST STRUCK THE ASSISTANT DIRECTOR OF NCIS; you're CO for this op."

Kolt shook himself free and glared atat Granger as he growled in the same voice he used on the roof, "I was just following through on my threat and for the record you ain't my CO dirt bag."

And with that he spun on his heel, entered Kensi's room and talked to her for about fifteen minutes then he disappeared.

Present Day

Kolt was just about to get up when his cell rang. He growled as he grabbed it from his nightstand and gruffly barked, "Go for Blye."

His handler Henrietta "Hetty" Lange said, "Kolt we need your help."

He asked, "With what Hetty? Is Kensi okay?"

She replied, "Yes, Yes she is quite alright."

Then she told him about the hunt for Isaak Sidorov and the 24 suitcase nukes. When she was finished he said, "I'll go to the Navy yard and the meet your team when they arrive."

Hetty said that will be just fine."

And with that he teminated the connection and chuckled as he lightly hopped up off the bed and disappeared into the bathroom. 5 minutes later he emerged and began to get dressed. He was a tall powerfully built man standing at 6′ 5″ tall and weighing 265 lbs. He had long shoulder length raven black hair that he kept pulled back in a low ponytail, ice cold liquid hazel eyes and a lightweight rugged black beard. He wore dark blue jeans, black tooled leather cowboy boots and a tight black t-shirt. He also had stainless steel dog tags around his neck, a black titanium MTM Patriot on his left wrist a .45 ACP black Wilson CQB Tactical LE with a Surefire X300 flashlight in a black Blackhawk SERPA Level 3 Light Bearing Duty Holster on his right hip, his encrypted BlackBerry z30 smartphone on his left hip, a two tone Detonics Combat Master in a black Galco Ankle Glove strapped to his left ankle and a black SOG SE18 Spec-Elite II Folding Knife in right hip pocket. He slid into his black leather Jacket,put on his silver mirrored RAY-BAN Aviators and put a pinch of Skoal in his cheek as he walked out and climbed into red 2017 Ford Regency MOAB and drove away.

Isaak Sidorov glanced at his assembled group of former Spetsnaz Alfa Group, GRU and Vympel operators as he spoke, "You have all heard the rumors about the 24 suitcase nukes in the 24 major US cities?"

At their collective nods he continued, "Well I can assure you it is not a rumor; It is indeed a very real fact."

As he spoke Quinn AKA Michelle Hanna stepped out of the shadows and up to his side. He said, "Aw my beautiful black widow; I'm so glad you could make it."

She replied, "I wouldn't have missed this for the world Isaak."

He nodded as they disappeared behind a heavy back curtain.

Granger and the rest of OSP were sitting in a nondescript dented gray Chevy cargo van listening as Sidorov spoke about the nukes. Granger breathed, I just thought that was a rumor. I can't believe it's true."

Sam asked, "Do you want to pull her out now?"

Granger shot him a look as he said, "We need more Intel Agent Hanna."

When Sam went to protest Callen fixed Granger with a look as he snarled, "Surely there's something you can do to guarantee Michelle's safety."

Granger asked in an exasperated voice, "As long as you've been doing this Agent Callen; have you heard of complete safety for a UC op?"

Callen shot him a withering glare as he replied in a low snarl, "I'm well aware of the fact there are no guarantees in our line of work Granger but I was wondering if there was somebody we could get to back her up?"

Granger was lost in thought as Hetty said over the COMMS, "I have asked Kolt and his team to assist us."

Kensi was overjoyed. She loved working with her older half-brother but she remembered what happened last time they had worked with the mercurial Delta sniper. She cut her eyes at Granger as she stated "You better keep your distance; otherwise you'll get your jaw broken again."

Granger rubbed his jaw as he thought back to that night 6 ½ years ago and remembered quite vividly how Kolt had flattened him with a right hook and broke his jaw in two places then Granger nodded as he said, I'll be fine Agent Blye me and Kolt have worked out our differences."

She just nodded as they headed back to OSP
