For the first time in weeks, there was something of a lull in the amount of cases coming through the laboratory, which had been good news for the majority of analysts, yet bad news for Sherlock. There were still some contracting from the local police departments, but it seemed as if even they were coming to a standstill, evidence hard to come by though crime was rampant. What cases Sherlock did get were usually easily solved and the reports were written, sent and filed quicker than they could be replaced. To keep himself from beginning to succumb to boredom, Sherlock had taken to various experiments alongside his ongoing attempt to solve the strange case from his dream world, alongside the dream phenomenon itself. One of the walls of his office was taken over by his list of current experiments, another he used for the dreams.
When the knock came at his door, Sherlock had been standing in front of the board regarding his currently tested theories. If he had been given the option, he would have told the person on the other side to turn himself around and speak with the secretary, because Sherlock rarely took any case without an appointment, something everyone in this laboratory knew all too well.
"I assure you, an appointment is needed," Sherlock answered without turning around. The dry erase marker in his hand continued to take down his notes on his ongoing tests, refusing to break his concentration for someone who had invited himself in. With his observations written down, Sherlock capped the pen and dropped it onto the small shelf. "Now what exactly requires my attention?"
Sherlock hoped that it was clear in his tone that he wasn't asking after the actual objects, but more on the case at hand. He could see from the tupperware container what was inside and he took up the object to study the contents after putting on a pair of gloves. The items were unremarkable, but from his brief assessment, he could narrow down the product brands to a much shorter list, though he assumed this man was looking more for the DNA contained within the samples.
