Sherlock was glaring at the map of the sewers he had jerryrigged together. While the blueprints were helpful in finding their way around, they failed to mention the various cave ins that had occurred in many of the tunnels, although they seemed to be on the right track, John was starting to lose patience, and despite his love of the game, he knew he would lose if he met the killer by himself.

The man obviously had some sort of fast acting sedative in his arsenal

(how else could he kill so quietly?) and despite the noise John made stomping around the sewers he couldn't ask for better back up (or bait depending on how things went)

John snorted a little in his sleep and Sherlock wondered at how he could even think about sleeping with the matter at hand. Though to, be honest, while the day had been irritating for him, it had been awful for John.

One of the tunnels had left John waist deep in sewage, and while Sherlock had to be careful wading through the filthy water, he had a much easier time of it, and hadn't managed to slip and fall and get completely soaked.

He considered plastering a fourth nicotine patch to his arm (as it was quite possible this was more than a three patch problem) but even he knew that was pushing it.

He was about to reach for the fourth patch when he heard someone fiddling with the door.

Sherlock silently stepped out of the line of sight and held his breath as the last latch clicked open.

The man who stepped inside was wearing a cheap jacket and a baseball hat; the man seemed to hone in on the sleeping John.

Sherlock couldn't see what he was doing to John, but knew that, as a rule, strangers who picked locks rather than knocking on doors rarely had good intentions.

So just as the man pulled out what looked like a knife, Sherlock already had his violins bow in hand, and he proceeded to beat the man about the head with it.

Obviously the stranger hadn't thought he was going to be met with resistance, so he ran off easily, but Sherlock couldn't stop him from taking the map.

"John! Wake up!" He shouted, John managed a drowsy mumble, so Sherlock gave him a hard slap on the face, that managed to at least rouse him partially.

"whassat for?"

"We've just been robbed, now get some clothes on, we got to catch him before he gets away"

Obviously whatever drug the

Man had administered to John had very short term effects, as John was already starting To become fully awake. He winced and held his cheek.

"good lord Sherlock, did you really have to slap me THAT hard?"

"it was the only way. Now hurry, I only managed to frighten him off, but we can still catch up to him if we hurry."

John fumbled with his coats and his boots. He stumbled after Sherlock as he ran down the hall towards the stairs.

At this point John realized something was wrong with his motor functions

"Sherlock, you didn't drug me to prove a point or something did you?"

He rolled his eyes.

"John that was ONE time , and no, our killer did. "
