"It means we know roughly when the next murder will occur," Alyssana declared, "though not so much where."  She peered at the marked map with a sigh.  "The murders are spread out across the city, far too large an area to patrol properly."  She stepped back, pacing slowly up and down the length of the room as she thought.  "I really don't think there's much more to be gleaned from what we have in the way of information.  If the note doesn't refer to a place but rather to the cycle of murders and moon phases, well.  I'm not sure what our next step should be."  Alys closed her little notebook and tucked it back in her pocket, along with the pencil she'd used for writing.
