AN: I've decided that I'm definitely going to try and continue with this now. Apologies if it takes me a while to get the first proper chapter up, I'm a little busy trying to plan out what exactly is going to happen with the whole thing.

Sherlock was growing impatient, pacing the floor and only looking up to occasionally glance at the bits and pieces of evidence that he had pasted on the sitting room mirror. Six people had been killed, poison slipped into their food or drink. They were never alone, though – always in pairs. "Any other leads, Detective Inspector?"

"None at all," replied Lestrade.

The detective let out a low breath, fingers locked beneath his chin. "Three double homicides in the past five days…"

"And not a thing to link them."

"Wrong." Sherlock muttered, stopping in front of the mirror, his grey tinged eyes scanning the information, bright in their revolution.

"What?"

"Wrong! Look at this. These two girls; they were much more that friends. Those men too; every bit of evidence suggests that they were lovers. And this last one, oh, they were only just engaged."

A phone beeped and Lestrade sighed, clearly reluctant to leave when it appeared that they were finally getting somewhere. Eventually he spoke, voice tinged with disappointment. "You work out what to do about the homophobic murderer; I'm needed back at the Yard."

"I need more evidence to single him out - we need to get him back." Sherlock sighed as Greg left, resuming his pacing. After a moment, he lifted his head, brow furrowed in concentration. "John! I need your help!"
