"Get in Sherlock."

"Why?"

"It doesn't matter, get in the car."

Silence.

"I see that you have been spending some time with Jim Moriarty."

"That is none of your business."

"It is very much my business when your time spent with him seems to be impacting on your marriage."

"I have no idea what you are talking about."

"Of course you don't which is why it is all the more tedious at I have to be the one to break it to you little brother. For all the deduction skills that you possess you cannot see what is right in front of you."

Silence.

"Six weeks ago you were begging me to try and put some kind of governmental pressure on John's doctors to try and get him discharged early, and now that he is home you're spending all your time with a man who has more than a few dubious contacts. Has he told you what he has been up to since your graduated."

"Yes."

"And how much did you detect was a lie."

The majority."

"And if it was anyone else you would have called them on it. Jim Moriarty has you hooked for some unknown reason and is taking up most of your time; time that could be better spent elsewhere where it is obviously becoming borrowed."
