A sharp knock on the shop door jerked Henry out of the reverie Abe's simple comment about Adam's past had thrown him into. His son began to push himself out of his seat; but the Doctor waved him back down, getting up himself to answer it.

He undid the lock and opened the glass door. "Jo?"

"May I come in?"

"Of course!" He stepped aside and waved her in, shutting the door behind her. "How may I help you?"

"What was your theory?"

"Pardon?"

"I don't know what you're keeping secret or what your reasons are for doing so are – but so help me, if you don't tell me what those test results came back with, I'll arrest your for obstruction of justice and tampering with evidence."

He raised his hands in surrender, seeking to calm her frustration and annoyance. "Detective -"

"No. You had a theory – no, not even that: you had the answer – that you refused to share, and I want to know why, if not what." She took a deep breath.

"Then why not confront me at the morgue when I left?" He asked, both to find an answer, and to stall for a few more moments.

"Because I know there is a reason for you feeling you need to hide this, and I don't want to unearth something that will endanger you or Abe or someone else."

"If you are unwilling to endanger another, and trust I have a good reason, then why confront me at all?"

"Because this has to do with the case as well – not just your secret!" Impatiently, she dropped her purse onto a table beside her. "Henry, you can't just keep hiding secrets from me – things about your past or memories are fine; but when it pertains to my case, I should know."

He hesitated, and she sighed.

"Look, Henry – just tell me what shook you up so much. The only time I've seen you that worried was when..." Her voice trailed off and her eyes widened as she made the connection.

He sighed, his shoulders slumping.

Her voice was quiet when she stated: "Adam's back, isn't he."

The Doctor nodded, finally answer her question. "The DNA results came back for a man with antibodies to extinct diseases such as Bubonic Plague, Pertrussian Fever, Cyprian Cough – a multitude of illnesses that a man would have had to be over two thousand years to contract. Perhaps there might be another immortal; but 'tis highly unlikely – especially one that is also as old as he claims to be."

"So when you said that there are some things the world had no answers for..."

"Yes, I did mean immortality." He sighed, continuing with his explanation. "Adam killed Julian – but I knew there was little point in pursuing him as he would only escape us by death, if not cunning; and we would be little better off."

She frowned. "Who else saw the results?"

"Pardon?"

"The results of the DNA test – who else saw them? You work with many doctors that would recognise the age of some of those diseases; is there anything that should be done?"

"No – it will likely be marked up to an error in testing or contamination of the samples: the mind will ignore what it will not accept."

She nodded, and then shook her head with a faint smile. When he tilted his head in confusion, she explained. "The thing about some cold cases is that it's impossible to punish the culprits, but this is one cold case where the killer will outlast the files."

Henry nodded, his smile more sad than hers.

"Henry, who is – hello, Detective."

She smiled, stepping around the Doctor to greet the shop-owner. "Hey, Abe." She frowned at the familiar green book he held in his hands. "What's that?"

He glanced down at it. "It's a record of Auschwitz – of the inmates there. Adam left it here."

"Adam was here, too?" She turned back to Henry with a jerk. "What happened?"

"Nothing happened." Henry frowned. "Adam says he will not harm Abraham due to what they both suffered at the Nazi's hands." He motioned towards the slender book his son held. "The ledger that he gave Abe seems to be some sort of an apology."

"That doesn't change anything about what he did to you, or Julian, or who knows who else throughout his life." She protested.

"No, it doesn't. But the acts of his life also don't negate his apology – twisted though it may be. That he is still willing and able to make amends means there is hope for him yet."

She was silent for a moment before surrendering to Henry's argument – half out of agreement, half out of knowing he was unlikely to change his mind. "Fine – but the moment I'm able to, I'll still arrest him for at least two counts of murder." She gestured towards the ledger. "But a record of Auschwitz's prisoners? I know Abe collects antiques; but why would that serve as an apology to you, Henry?"

Henry hesitated, glancing towards his son for direction. Abe shrugged and explained, joy lighting up his eyes.

"The record...Auschwitz was where my parents were – where I was born. This ledger tells me who they were."

"Oh, Abraham – that's wonderful!" She exclaimed, mentally setting the matter of Adam aside for another day. "I'm glad you were able to find out. Not that they were there, of course – just that you now know who they were, and -"

He interrupted her. "It's fine. I know what you meant. Hey," He hesitated, "Did you want to come?"

"Come? Where?"

Henry reentered the conversation. "Tomorrow, we will go down to the Archives to see if there is anything from his parents there."

"Oh, but I wouldn't want to intrude – I mean, that's personal; and that's your family..."

"Jo. You're family too, remember? Come on – I want you to."

She hesitated, but could hear the sincerity in Abe's voice. With no objection forthcoming from Henry, she agreed. "Fine – but I'll drive. Henry would probably be a sterling example of why horses bolted from automobiles -"

"I take offense at that remark," He protested, taking off his coat.

"Well, deal with it. And you, Abe, will be too distracted to drive safely. I'll at least get us there with minimal casualties."

"Yes, very funny, Detective – I'll have you know I had the best teacher."

"Oh? Did Abigail teach you?"

"No. Experience did."

She laughed, nearly collapsing when she saw the affronted expression on Henry's face. It was nice to see confirmation that this discovery of Abe's wouldn't change anything between the two of them – that Henry would still be Abe's father.

AN: I'm still uncertain as to how this turned out, but cannot make it agree with me on my own. As it is, thank you so much for taking the time to read this! Gramercy, and God bless you!
