Murder by Boojum

A brutal serial killer stalks members of the Southern California branch of The American Lewis Carroll Society, targeting members of a mysterious and highly secretive Snark Club within the Society that meets once a year in San Diego's fabled Hotel del Coronado to celebrate and appreciate Carroll's epic nonsense poem, "The Hunting of the Snark". After the first few murders, the killer, who intentionally leaves Snarkian clues, is tagged by the media as "The Boojum", since the monster's victims, collectors of rare editions of Carroll's classic nonsense work, figuratively "vanish" when the killer strikes. Who is the Boojum? What is the Boojum's motive? Will all ten hapless members of this strange group die before the police can stop this Snarkian reign of terror? Is it even safe for anyone in the Society to own more than one copy of Carroll's darkest work?
