The Sixes by Kate White

Author Phoebe Hall is taking some time off from writing, teaching journalism at Lyle College. When a student is found, drowned, in the river after Phoebe had talked to her, Phoebe feels her investigative juices warm up. Secret societies, lies, people missing. All these things seem to be coming together, causing even Phoebe to fear that something evil was about. Lots of darkness, lots of investigating, lots of "I need to talk to you in person" conversations. An ok read.
