Hello all, I currently have a lot of work so I might not be able to update regularly. But anyway, I hope you'll enjoy this chapter. And don't hesitate to review, I always appreciate them. :)

Thankfully, the rest of the morning went much better for Sherlock. First, Lestrade had called him to have a look at possible first attempts. As he said to John the day before, the detective knew that there wasn't anything to be found, yet, it did provide him with a distraction from the fidgety mood he'd been on since he'd received Molly's text. So, he sat at Scotland Yard with the detective, reviewing the cases the man had excavated to see if anything matched. Unfortunately for the policeman, Sherlock was easily bored and as Lestrade was reading aloud yet another report, the detective blurted:

"There hasn't been a first attempt."

Greg froze. Did the git said what he thought he'd said?

"What do you mean there wasn't a first attempt?" he asked inquiringly.

"There wasn't. It was the first time for the aggressor." Replied Sherlock. At the look on Lestrade's face he found himself justifying it. "Well, if you had listened to Molly Hooper, you would have find out. It was clearly the work of an amateur that hadn't cut anyone before."

"You bloody git! Do you know how much time we spent in trying to gather all those old cases?"

"Well, from your rumpled clothes, the blood injected eyes of your men as well as the overwhelming scent of badly brewed coffee. And yes, before I forget, Donovan didn't even manage a look of disgust when I arrived, no she even looked relieved. Well, obviously, you and your squad stayed the whole night?" deduced Sherlock.

At the murdering glances he received from the men and women in the office, Sherlock had a sudden inkling that maybe this was a bit not good. However, when he thought that some of them were considering clubbing him to death, Donovan arrived with some files and just cut the tension:

"We received a new tox report. This one by Molly, much better than the dumbass' that did the first. Oh, and she sent some other tests too. Ones we didn't request." Said the curly haired woman matter-of-factly.

"I did." Said Sherlock, refusing to air the sigh of relief at the interruption of Donovan. He gingerly took one of the files from the young sergeant's hands and browsed its contents rapidly. He then took another and kept up until he had perused all the files. Entranced as he was by the results, he didn't see Lestrade glaring at him with a look of utter disbelief before glancing at Donovan. The woman just hunched her shoulders back at him and sat on the chair at her desk. Finally, after some time, Sherlock turned to Lestrade and said:

"Ah, finally, there might be some clue on where the first part of the crime occurred." He said, before looking around him. The men that had been there earlier were all gone, only leaving him, Lestrade and Donovan in the room.

Donovan, who had somewhat rested her head on her crossed arms, managed a groan before replying grumpily:

"Not possible. Molly told me she couldn't find anything relevant. Please don't send us in one of your merry chases now." Her tone was almost pleading.

"Are you sure of yourself Sherlock?" also doubtfully asked Lestrade.

"Lestrade, sometimes I wonder how you manage to actually catch criminals without me… The clue is the absence of clue! What do we have? Nothing! No cement dirt, nor any more common variety, no shards of wood, no trace of fabric or vegetal. Nothing, the victim was killed in an almost sterile environment! Not that many isolated locations that would have such qualities. So, of course, we can dismiss abandoned buildings and such as they're certainly not be in pristine conditions. So we're looking for a tiled room – much easier to clean – in a building that is not abandoned but obviously condemned for some reasons. Not restaurants – populated areas, not really the most discreet way to murder someone. So, of course a slaughterhouse or something akin closed by sanitary inspection – any remnants of blood that the killer couldn't wash would be attributed to a much more mundane cause. So, now we know what to look for!" Sherlock was almost giddy with the revelation.

However, apart from a doubtful look shared by the two officers of the law, Sherlock couldn't elicit as vivid reactions as he expected. Damn, how inconvenient that John had to work today. He was always such the fervent admirer. Lestrade and Donovan, on the other hand, not so much. They sighed heavily as they both stood up from their chairs. At that Sherlock stilled:

"What now?" he asked almost pouting at their lack of reaction to this new turn in the investigation.

"Now, we go get some rest." Replied Lestrade dismissively. Before Sherlock could even open the mouth, the DI cut tin "We're toast with Sally and the first crime scene isn't going anywhere, so now, we're going to sleep." He finished with a voice that didn't allow for argument.

As he and Donovan exited the room, he finally tossed back "And don't tell me that you don't want to go and have a look for yourself without us."

Sherlock, first taken aback, finally smiled. Lestrade's deduction skills seemed to eventually improve with time. So he stayed behind and made good use of the police database to look for what he wanted. Nobody interrupted him nor questioned his presence in the otherwise empty office. However, nothing in the database gave away any building that matched the description he gave Lestrade and Donovan. He almost sighed at the uselessness of the Met's tools. He'll have to rely on his network of course. Before getting up, he sent a few messages to the individuals he found were the best qualified for the task. For a few seconds, he hesitated to pull Wiggins from his current task of watching Dr Hooper. After all, she was already followed by his brother's agents. But finally decided against it. With that, he got up and smiled when his phone beeped with an incoming text. It was John and finally, the doctor seemed to have taken an interest in the case as he proposed to join him for the afternoon. And the fact that he proposed to meet up at Bart's was neither displeasing. Sherlock would have time to check in on his current experiments while waiting for news from his irregulars.

So, any thought about what he'll face when he'll be at Bart's?
