Later in his quarters Hammerhand examined the neural shredder. The only marks on it were from the ordinance blasts.
"No obvious way to disassemble it, ", thought Hammerhand.
"Still a few scans may give me some data before I attempt disassembly. Which I will do cautiously no matter how hard Inquisitor Hawk pressess. No doubt it will be booby trapped unless opened with a specific tool".

With that thought Hammerhand made his way to Sophia's quarters. Crossing the battle scarred streets of Dogbelly Hammerhand saw a few commissars who had arrived with some Chem Dogs. "Some more dogs in Dogbelly" thought Hammerhand. I need to keep a tight grip on my tools and anything else light enought to carry off as the Chem Dogs are notoriously light fingered."

At Sophia's quarters the light were on. Hammerhand could see movement behind the blinds.
Feeling worried Hammerhand knocked on the door and waited. No one barged into an assassins quarters except those with a death wish even if the assassin was known to be dead.

"Yes," Shouted a familiar voice from within." A chill ran down Hammerhands spine. The voice was Sophia's. He turned away and darted around the corner.

Best to speak to Hawk he thought.

At Hawks Headquarters in a private meeting Hammerhand explained that he had acquired a neural shredder as aconsequence of the battle. But despite Sophia disappearing into a melee of Chaos Renegades that had to be stopped with some ordinance she was now once again in her quarters.

"Interesting", remarked Hawk, "Examine the neural shredder as top priority. Keep an eye on Sophia". "I wonder how the guild does it within the Imperial Decrees on cloning?".
"Go now". "By the way the Grey Knights leave tomorrow."
"Ah, that explains the Chem Dogs arrival tonight, will we be deploying our less conventional weapons when the assault renews?", asked Hammerhand.
"Yes", snapped Hawk. "Keep it to yourself at the moment and keep a tight grip on your tools and that neural shredder with the Chem Dogs around."
"Dismissed".
