Basil sat in his chair, looking at the fire with the folder on his lap, smoking his pipe. He was almost to a decision of what to do with it and with the thief, Isabelle.

His ears twitched when he heard a click and very light footsteps. His hand casually went to the revolver on his side table and load it. He heard the footsteps stop behind his chair and a small click. He swiftly got up and pointed the gun at his intruder, who was also pointing his gun at him.

"Who are you?" he said, couldn't see the man's face , "Why are you here?"

The man tilted his head and chuckled.

"No wonder Ratigan is always uncomfortable when he see's me." he said.

That comment made Basil pull back in confusion. The intruder just chuckled again and removed his fedora, making Basil gasped out loud.

The intruder looked exactly like him, except his fur was darker then his and his green eyes were...hollow.

"I'm Neil Cassidy." he said, "I'm Isabelle's cousin."

Basil nodded with a sigh.

"You want the folder."

Neil growled and his grip on the gun tightened.

"You damn right I want it! I never want Isabelle to remember that, you have no idea how much this nearly destroyed her."

Basil sighed and looked at Neil with determination.

"She still broke the law." he said, making Neil scoffed.

"Let me ask you something, detective." he said tightly, "What would you have done? If that was your sister or your friend that ugly act was inflicted on and she had no justice, what would you have done?"

Basil was shocked by the question and he tried to say something, but only stammered his words, making Neil smirk.

"You can't answer that, can you? Because the answer is too terrifying, isn't it?"

Neil then sighed and glared at Basil, cocking his gun.

"I'm going to take this to my grave Basil and don't make me put you in yours."

Basil sighed as he put down his gun and picked up the folder. He held it up and suddenly threw it in the fireplace. He then looked at Neil, who just stared at him with wide eyes.

"its out of my jurisdiction anyway." Basil said, "If I'm going to arrest her, it will be here in London."

Neil looked at Basil and then suddenly grinned.

"That's if you could catch us." Neil said, then running out the door, leaving a bemused detective behind. Basil then sat down in his chair, continuing smoking his pipe.

He will catch them sooner or later. But he thinks the choice he made with the this cold case was the right one.

AN: Here we have the conclusion of The Cold Case of Isabelle Cassidy.

Basil and Neil finally meet each other, Basil is freaked out and Neil is just amused. So, here we have our boys have a heart for heart. Basil tries to say she still broke the law, but Neil asks Basil a very good question, what would he have done? The answer is too scary to say, and Neil knows that.

We also see how far Neil will go for his cousin and how he will kill Basil so Isabelle will never find out. He's all about family unity and stuff like that. He also sucks at stealth, that's why he always sends Isabelle to steal stuff.

I was originally going to have Basil just give the folder to Neil, but I thought it will be better if he burned it himself. So, now the Cassidy's have a new found respect for Basil, but that still doesn't mean they are not going to rub their robbery in his face.

Anyway, enjoy, I hope you all liked this story! Comments are loved! I don't own GMD, just Neil and Isabelle!
