Sophie Swift Goes Out on a Limb

We did it, y'all. Me and my merry band of misfit friends solved a murder and managed to NOT get ourselves killed in the process. Barely. Sure, it was all a little more "Scooby-Doo" meets "The Three Stooges" than "CSI" meets "Sex in the City", but we'd succeeded. And now, it's back to business, living a normal life filled with boring office meetings and training interns. Huzzah!
But when one of the new interns gets an all expense paid trip to the Pearly Gates courtesy of a homicidal maniac, what choice do we have except to dust off our magnifying glasses and figure out who killed her?

(None. The answer is none.)
